Description

Extraction method of pressure jump

More particularly, the present invention relates to a method of extracting a barometric pressure jump, more specifically, a barometric pressure data of a 1-minute interval observed through a weather observation device is averaged at intervals of 10 minutes, The present invention relates to a pressure jump extraction method for extracting a pressure jump by determining that a pressure jump occurs when the difference in pressure is equal to or greater than a constant pressure difference.

Generally, the Meteo-tsunami phenomenon refers to the phenomenon that the resonance is formed when the moving speed of the mobile low pressure and the sea wave move at the same speed, so that the wave height increases at the coast. Generally, It is inferred that the deep sea waves and low pressure occur when they move side by side at similar speeds and directions.

In other words, the above-described weather tsunami inferred that the atmospheric pressure jumping phenomenon occurred in the frontmost part as the low pressure passed, causing the sea surface to change and causing the tsunami to reach the shore due to the long-range and resonance of the ocean.

The above-mentioned weather tsunami increases the level of water level due to the resonance phenomenon when the energy propagated from the shore or the shore where the water depth becomes shallow is amplified or the disturbance is externally similar to the natural period (subduction) An accident occurs because the digging suddenly increases.

For example, when a person's footsteps in a coffee cup coincides with the period of vibration of the coffee, coffee can be said to flutter. If the period of the ripples coincides with the moving speed and direction of the atmospheric pressure, a weather tsunami can occur even if there is no strong external force due to summer typhoon, strong wind or earthquake.

In fact, on Sunday, May 4, 2008, nine people were killed and 15 others were injured in a sudden surge of waves on the Jukdo pavement in Nampo-myeon, Boryeong, Chungcheong Province. Also, on March 31, 2007, there was a sudden high wave on the coastal residential area of Yeonggwang-gun, Yeonggwang-gun, Jeollanam-do, and the houses were flooded and the ship was overturned. Such a tsunami occurred in Hwangpo, Hanlim-myeon in February 2005 as well.

As described above, the weather tsunami, which has no clear cause, is occurring worldwide in Asia, Europe, and South America, and studies are being actively conducted. Especially in Japan, Spain, Croatia, the United Kingdom and Argentina, there has been a long history of damages to ports, ships, and people due to atmospheric disturbances, atmospheric pressure jumps and weather events due to weather conditions.

On the other hand, in order to reduce the damage caused by the above-mentioned weather tsunami, various researches and efforts have been made in our country as well as all over the world. However, research has shown that atmospheric disturbances, atmospheric pressure jumps, and weather factors play a major role in AWS and radar observations located in coastal and inland areas as the cause of the weather.

In addition, the range of pressure jumps proposed through various studies and efforts to reduce the damage caused by the above-mentioned weather tidal wave can be found in the literature from 1 to 6 hPa (K. Tanaka (2101), IVICA VILIBIC et al. ). This is based on the fact that damage occurred when the pressure jump range of 1 to 6 hPa resulted from research efforts on weather tsunamis.

However, as described above, atmospheric pressure disturbance, atmospheric pressure jump and meteorological factors are mainly attributed to the cause of the weather tsunami, but there is no report on a more objective and reasonable measurement method of the pressure jump.

Therefore, as mentioned above, considering the fact that the occurrence of atmospheric pressure jumps can cause damage to people's property and property in the coastal area, forecasting of weather tsunamis is expected through prediction of weather tsunami and real-time observation through it .

FIG. 1 is a flow chart showing a process of a pressure jump extraction method according to the present invention. FIG.
FIG. 2 is a flow chart showing another embodiment of a method for extracting atmospheric pressure jump according to the present invention. FIG.

Hereinafter, the atmospheric pressure jump extraction method according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a process of a pressure jump extracting method according to the present invention.

First, in the technical construction relating to the pressure jump extraction method according to the present invention, when the atmospheric pressure jumping occurrence is judged based on the pressure fluctuation width of 1.5 hPa, Based on the fact that the damage occurred at a pressure fluctuation of 1.5 hPa or more, the pressure fluctuation range was 1.5 hPa when determining the pressure jump occurrence.

As shown in FIG. 1, the process of extracting the atmospheric pressure jump according to the present invention includes: (a) collecting barometric pressure data at intervals of one minute for a plurality of marine areas in real time (S100); (b) The average value of the sea surface pressure of the time series collected in step S100 is calculated at intervals of 10 minutes and the mean value of the sea surface pressure is calculated from the average value of 10 minutes interval calculated in step (b) (S110) (S120), (d) a step of analyzing whether the difference of the sea surface pressure is 1.5 hPa or more over the data calculated through the step (c) (S120) The time when the difference of the sea surface pressure becomes 1.5 hPa or more for one hour when the difference of the sea surface pressure is 1.5 hPa or more for one hour through the step (S130) and the step (d) (S140). ≪ / RTI >

In other words, the extraction of the atmospheric pressure jump according to the present invention extracts the sea surface pressure data (raw data) for the waters of the meteorological observing equipment installation point from each weather observation equipment installed on the coast of the country as in the step (a) (S100). At this time, the sea surface pressure data collected from the meteorological observation equipment is the sea surface pressure data of 1 minute interval.

Next, as described above, the barometric pressure data at intervals of one minute are collected in real time through a step (a) (S100), and then the sea surface pressure of the time series collected in the step (b) The data are averaged at intervals of 10 minutes (S110). At this time, in order to quantitatively analyze the time of occurrence of the atmospheric pressure jump, in the present invention, the time at which a magnitude of a certain energy or more appears on the basis of energy is presented as a time of arrival. For this, time series data are shown as time and period energy changes using the wavelet technique as shown in Table 1 and Table 2.

Table 1 and Table 2 show the results of the survey on March 31, 2007 at 00: 49 ~ 01: 30, 2007 when the sudden high waves hit the coastal residential area at Yeonggwang- The sea surface pressure data collected from the Boryeong and Seosan meteorological instruments collected at 1 minute intervals are shown in time series as the change of energy according to time and period. At this time, the red waveform on the graph is the data of the principle data, and the blue waveform is the data of the 10 minute average.

Meanwhile, in the case of Tables 1 and 2 as described above, in order to show whether or not the hypothesis of the pressure jump extraction process according to the present invention is correct, The examples in Tables 1 and 2 show a case where a pressure difference of 1.5 hPa or more, which is the baseline of the pressure jump, occurred, and a pressure jump occurred at an air pressure difference of 3 hPa or more.

Of course, as in the cases shown in Table 1 and Table 2, when the difference in sea level pressure is 3 hPa or more, in addition to the case where the atmospheric pressure jump has occurred, the case in which the atmospheric pressure jump phenomenon occurred from the time point when the difference in sea level pressure is 1.5 hPa, This case was taken as an example because it was judged that the case occurred at Yonggwang-gun, Yeonggwang-gun, Chonnam on March 31, is the most suitable to explain the atmospheric pressure jump phenomenon.

That is, the graphs of Tables 1 and 2 as described above can be used as a representative example of the weather tsunami, which is observed at Boryung and Seosan between 00: 49 and 01:45 on March 31, 2007, (3 days of sea level pressure data including the occurrence of the tsunami) from the meteorological office to indicate the sea level pressure data of the time series in terms of energy change with time and period, And it is an example for verifying whether the hypothesis of the pressure jump extraction process according to the present invention is correct.

In the example of Table 1 and Table 2 as described above, in the movement range calculation data of the lower portion of the graph, the red horizon line shows a time point of at least 3 hPa at which the atmospheric pressure jump occurred in the air pressure difference of 1.5 hPa or more, which is the baseline of the air pressure jump .

Next, as described above, the barometric pressure data of the time series collected through the step (b) (S110) are averaged at intervals of 10 minutes, and then the calculated 10-minute intervals The moving range of the one-hour interval with respect to the sea surface pressure is calculated through the average value (S120).

If the moving range of the one-hour interval with respect to the sea surface pressure is calculated through the calculated average value of the 10-minute interval calculated by calculating the moving range of the one-hour interval with respect to the sea surface pressure through the average value of 10 minutes interval calculated as described above, As shown in Table 1 and Table 2, a waveform graph can be obtained for each time.

Next, as described above, the moving range of the one-hour interval with respect to the sea surface pressure is calculated through the average value of the 10-minute intervals calculated through the process (S120) in the step (c) (S130) whether or not the difference in sea surface pressure is 1.5 hPa or more for one hour.

In other words, as shown in Table 1 and Table 2, it is determined whether the difference of the sea surface pressure is 1.5 hPa or more for 1 hour among the sea surface pressure data for 3 days including the weather tsunami occurrence period, Analyze. As shown in Table 1, it can be seen that the fluctuation width of the large waveform at 00:49 on March 31 is not less than 4 hPa, and the fluctuation width of the large waveform at 00:10 on March 31 is not less than 3 hPa as shown in Table 2.

In fact, there has been a record of a number of hours of westerly tsunami occurring on the West Coast from 00:40 on March 31, 2007. In other words, at 1:10 am on March 31, 2007 houses, vehicles and vessels of truth and fines were buried in Buan-gun, Jeollabuk-do, Jeollanam-do, and at 1:30 the vessels that were moored at Myeolsan-myeon, . At 1:50 pm, one person died and a commercial vessel and a ship were flooded in the vicinity of Yeonggwang Nuclear Power Station discharge facility in Yeonggwang-gun, Jeollanam-do, Hongseong-myeon Pohang, Hongongnong, Baekwu and Hwaseong in Jeollanam-do. In 2:00 pm, House, ship and casualties occurred. At this time, the atmospheric pressure jump occurred in 2007 at an average speed of 68.7km / h.

Of course, as mentioned above, there is a difference between the time of occurrence of the atmospheric pressure jump and the time of occurrence of the damage in the west coast, but this is due to the difference in the distance from the sea area where the atmospheric pressure jump first occurred to the west sea coast .

Meanwhile, when the difference of the sea surface pressure is less than 1.5 hPa for one hour in the process of analyzing whether the sea surface pressure difference is 1.5 hPa or more during the one hour of the step (d) (S130) as described above, It is determined that the atmospheric pressure jump extraction process is to be performed (S160).

Next, when the difference of the sea surface pressure is 1.5 hPa or more for one hour through the step (d) (S130) as described above, the time when the sea surface pressure difference becomes 1.5 hPa or more for one hour as in the step (e) It is determined that the atmospheric pressure jump has occurred (S140).

In other words, as in the above-described step (e) (S140), when the difference of the sea surface pressure is 1.5 hPa or more for one hour, the time when the sea surface air pressure difference becomes 1.5 hPa or more is determined as the atmospheric pressure jump occurrence time When there are a plurality of times when the difference of the sea surface pressure is 1.5 hPa or more for one hour, the first time shown is determined as the atmospheric pressure jump occurrence time.

On the other hand, in the case of the case shown in Table 1 described above, the time point when the sea surface pressure difference is equal to or more than 3 hPa for 1 hour from 0:00 to 1:00 is described as the time of occurrence of the atmospheric pressure jump, On the 31st, there was no damage incident on the waterfront due to the atmospheric pressure jump occurred in the sea surface pressure difference of 1.5 hPa or more before 0 o'clock.

However, assuming that the case of Table 1 and Table 2 is the current point, assuming that there is a time when the sea surface pressure difference is 1.5 hPa or more during 1 hour before March 31 on March 31, The time when the sea surface pressure difference is 1.5 hPa or more is determined as the atmospheric pressure jump occurrence time.

Next, after the atmospheric pressure jump occurrence time is extracted from the sea surface pressure data collected in real time through the above-described step (a) from step S100 to step (e) step S140, An alarm according to the occurrence of the atmospheric pressure jump is issued (S150) to the coastal area where the atmospheric pressure jump occurs, so that the damage to the person and the property can be prevented.

On the other hand, the atmospheric pressure jump generated as described above can be divided into classes. That is, the generated pressure jump is classified into a first-stage grade of 1.5 hPa or more to less than 2.0 hPa, a second-stage grade of 2.0 hPa to 2.5 hPa, a third-stage grade of 2.5 hPa to 3.0 hPa And 3.0 hPa, which is the 4th grade of the highest strength.

As described above, the atmospheric pressure jump zone divided into the classes can be alerted according to the grade at the time of issuing the alarm according to the occurrence of the atmospheric pressure jump as in the step (f) (S150) have.

As described above, the atmospheric pressure jump extraction technique according to the present invention can collectively calculate the time of occurrence of the atmospheric pressure jump, and it can be said that it is very objectively and rationally based on the occurrence of the difference of 1.5 hPa or more.

Meanwhile, in order to obtain more accurate and good results in the process of extracting the atmospheric pressure jump according to the present invention as described above, it is necessary to collect the sea surface pressure data collected in the step (a) (S100) It would be better to do it. Currently, there are more than 15 coastal disaster prevention observation systems installed on the coast, including the west coast of Korea, and it is known that the sea surface pressure can be observed.

Therefore, in case of a pressure jump phenomenon in a sea area in the west coast, the time difference will be observed in the weather observation equipment installed in the west coast region, but the barometric pressure is observed in each weather observation device in 1 minute interval.

Meanwhile, in order to improve the accuracy of the technique for extracting the atmospheric pressure jumping occurrence according to the present invention as described above, the distance between the installation points of the weather observation equipment should be better than 10 to 100 km.

As described above, the technique relating to the atmospheric pressure jump extraction according to the present invention is characterized in that the barometric pressure data collected at one minute interval (S100) is collected in real time (S100) and the barometric pressure data of the collected time series is collected for 10 minutes (S110). Then, the moving range of the one-hour interval with respect to the sea surface pressure is calculated through the calculated average value of the intervals of 10 minutes (S120).

Subsequently, it is analyzed (S130) whether or not the difference of the sea surface pressure is 1.5 hPa or more for 1 hour through the data calculated as described above. Then, when the sea surface pressure difference is 1.5 hPa or more for 1 hour, It is determined that the atmospheric pressure jump has occurred (S140).

By extracting the occurrence of atmospheric pressure jump through the above-described process, the present invention can be applied to a forecasting system for preventing damages to the coastal area due to occurrence of weather tsunamis.

FIG. 2 is a flow chart showing another embodiment of a method for extracting a barometric pressure jump according to the present invention.

2 is a view showing another embodiment of a method of extracting atmospheric pressure jump according to the present invention. FIG. 2 is a flowchart illustrating a method of extracting atmospheric pressure data of a plurality of marine areas at intervals of one minute in operation S200, (A) and (b), the mean value of the sea surface pressure data collected during the process of step (S210) and the step (B) A step S230 of analyzing whether the sea surface pressure difference is 1.5 hPa or more for one hour through the data calculated in the step (S220), (D) and (C) (D), it is determined whether the difference of the sea surface pressure is 1.5 (1) through the process (S240) and the step (E) of analyzing whether there are three or more places where the sea surface pressure difference is 1.5 hPa or more for 1 hour. If there are more than 3 places in hPa and more than 1.5hPa difference Determining the time of the pressure jump occurrence time and comprises a configuration including the step (S250) determines that the pressure jump occurred.

In the atmospheric pressure jump extraction process according to another embodiment of the present invention as shown in FIG. 2, step (A) from step S200 to step (D) (S100), and the barometric pressure data of the collected time series is averaged at intervals of 10 minutes (S110).

However, only the process from step S240 to step G260 of the atmospheric pressure jump extraction process according to another embodiment of the present invention will be described.

As described above, whether or not the difference in sea surface pressure is greater than or equal to 1.5 hPa for one hour is analyzed through step (D) (S230), and the data of the sea surface atmospheric pressure difference for one hour is 1.5 hPa or more. (S240) whether or not there are three or more places where the difference in sea surface pressure is 1.5 hPa or more for one hour as in FIG.

As described above, in the process of extracting the atmospheric pressure jump of another embodiment according to the present invention, it is analyzed (S240) whether there are three or more places where the sea surface pressure difference is 1.5 hPa or more for one hour as in the step (E) The accuracy of extraction can be further improved. In other words, it is analyzed whether data of sea surface pressure difference of 1.5 hPa or more for one hour is observed in three or more meteorological observation equipments.

Next, as described above, it is analyzed through step (E) (S240) whether or not there are three or more places where the difference in sea surface pressure is 1.5 hPa or more for one hour, When the difference of the sea surface pressure is more than 1.5 hPa, the first time when the difference of the sea surface pressure becomes 1.5 hPa or more is determined as the atmospheric pressure jump occurrence time and it is judged that the atmospheric pressure jump occurs (S250).

Meanwhile, when the difference of the sea surface pressure is 1.5 hPa or more for one hour as in the above step (F) (S250), the case where the difference of the sea surface pressure is 1.5 hPa or more for three hours or more is analyzed, The time at which the difference of the sea surface pressure is 1.5 hPa or more for the first hour is determined as the atmospheric pressure jump occurrence time.

Next, the atmospheric pressure jump occurrence time is extracted from the sea surface pressure data collected in real time through the above-described step (A) (S200) to step (F) (S250), and then, An alarm in accordance with the occurrence of the atmospheric pressure jump is issued (S260) in the coastal area where the atmospheric pressure jump occurs, thereby preventing damage to the person and the property.

The atmospheric pressure jump generated as described above can be divided into classes. That is, the generated pressure jump is classified into a first-stage grade of 1.5 hPa or more to less than 2.0 hPa, a second-stage grade of 2.0 hPa to 2.5 hPa, a third-stage grade of 2.5 hPa to 3.0 hPa And 3.0 hPa, which is the 4th grade of the highest strength.

Accordingly, as described above, the atmospheric pressure jump zone divided into the classes can be alerted according to the grade at the time of issuing the alarm according to the occurrence of the atmospheric pressure jump as in the step (F) (S250) I can do it.

As described above, the atmospheric pressure jump extraction technique according to the present invention can collectively calculate the time of occurrence of the atmospheric pressure jump, and it can be said that it is very objectively and rationally based on the occurrence of the difference of 1.5 hPa or more.

Meanwhile, in the process of analyzing whether the sea surface pressure difference is 1.5 hPa or more during the one hour of the step (D) (S230), when the sea surface pressure difference is less than 1.5 hPa for one hour, The process proceeds to step S200 where the atmospheric pressure jump extraction process can be resumed at step S270.
