All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present application, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
The method for determining a typhoon simulation area provided by the embodiment of the application is applied to a typhoon simulation area determining system, and the typhoon simulation area determining system is used for determining a simulation area of typhoons in a target area in a forecast period, wherein a plurality of forecast moments are set in the forecast period, as shown in fig. 1, and the method can comprise the following steps:
And step 101, obtaining typhoon messages corresponding to the forecast time at each forecast time.
In the embodiment of the present application, the forecast period and the target area need to be preset. The forecasting period is a period of time for which typhoon forecasting is required, and comprises a starting time and a terminating time, and specifically, the forecasting period can be determined by directly setting the starting time and the terminating time, or the forecasting period can be determined by setting a first forecasting time, a last forecasting time, a duration of each forecasting time and a time interval of two adjacent forecasting times. The target area is an area needing typhoon forecasting, and specifically, the target area can be determined by directly inputting the longitude and latitude of the area needing typhoon forecasting.
The forecasting time period is provided with a plurality of forecasting time points, wherein the forecasting time points can be arranged at equal intervals or unequal intervals, the number of the forecasting time points in the forecasting time period can be determined according to actual forecasting requirements, the frequency of forecasting, the strength of target typhoons in the target area and the like, and the method is not particularly limited. And obtaining typhoon messages corresponding to the forecast time at each forecast time. Specifically, the typhoon message is issued by a typhoon forecasting and early warning mechanism and can be used as a basis for judging whether typhoons exist in the target area. In the forecasting period, the typhoon simulation area determining system can detect from the starting time of the forecasting period, and when the forecasting time is detected to be reached, typhoon messages at the current time, namely typhoon messages at the forecasting time, are obtained from messages issued by a typhoon forecasting and early-warning mechanism. The typhoon message comprises the current forecasting time and all typhoons in a preset area, wherein the preset area is an area in which typhoons are released by a typhoon forecasting and early warning mechanism according to actual requirements, and the area is larger than the target area.
Step 102, determining at least one target typhoon corresponding to the target area according to the typhoon message.
The typhoon message obtained at the forecasting time comprises all typhoons of which the current forecasting time is in a preset area. Through the typhoon message, the typhoon condition in the target area can be determined, and specifically, the typhoon quantity and the serial number of each typhoon can be determined. When the typhoons are equal to or greater than 1, any typhoon in the target area is the target typhoon.
Step 103, aiming at the target typhoon, acquiring first forecast information of the target typhoon in a first forecast mode in a forecast time interval corresponding to the forecast time, wherein the starting time of the forecast time interval is the forecast time, and the first forecast information comprises a first simulation area of the target typhoon in the forecast time interval corresponding to the forecast time.
The typhoon quantity in the target area can be determined according to the typhoon message, and after the target typhoon in the target area is determined, the first forecast information of the target typhoon in the first forecast mode in the forecast time interval corresponding to the forecast time can be further obtained, so that the first simulation area of the target typhoon in the forecast time interval taking the forecast time as the starting time can be determined. The first simulation area is an area in the first forecasting mode, which is used for simulating the target typhoon in a forecasting time interval corresponding to the forecasting time.
Specifically, for each forecasting time, a corresponding forecasting time interval may be set, where the forecasting time interval is smaller than the forecasting period, the starting time of the forecasting time interval is the forecasting time, and the ending time of the forecasting time interval is determined according to the duration of forecasting in specific current needs, and optionally, for a plurality of forecasting times in the forecasting period, the corresponding forecasting time intervals may be the same or different. The length of the forecasting time interval can be determined according to the typhoon number and/or typhoon intensity at the current forecasting time, and the application is not particularly limited.
According to the embodiment of the application, the simulation areas of each forecasting time and each target typhoon in the target area in the forecasting time interval are obtained, so that the position and coverage range of the simulation area of the target typhoon in the forecasting time interval can be dynamically adjusted according to the actual typhoon situation and the forecasting time interval at the forecasting time. Compared with the situation that the position and coverage range of the simulation area are unchanged all the time in the forecast period, the method can reduce calculation time consumption of forecast and avoid storage space waste.

It should be noted that, the second forecast information of the target typhoon corresponding to the second forecast mode may be directly obtained from the corresponding system using the second forecast mode according to the typhoon number of the target typhoon. The second forecast information comprises a second motion track of the target typhoon in a forecast time interval corresponding to the forecast time, and under the condition that the second forecast information of the target typhoon in a second forecast mode is known, the first forecast information can be determined according to the resolution of the first forecast mode and the second forecast information, and the first forecast information is the forecast information of the target typhoon in the first forecast mode.
In the above embodiment of the present application, when the first forecast information of the target typhoon in the first forecast mode is obtained in the forecast time interval corresponding to the forecast time, the first forecast information may be determined by obtaining the second forecast information of the target typhoon in the second forecast mode and the resolution of the first forecast mode. Therefore, the calculation process is simpler, and the accuracy of typhoon forecasting can be ensured.
In an alternative embodiment of the present application, the first simulation area is an area defined by tangents to the second motion trajectory in a plurality of target directions.
Optionally, the first simulation area is a closed area formed by tangents of the second motion track in multiple target directions.
For example, the target direction may be four directions of east, south, west and north, and the first simulation area may be a rectangular area determined by a tangent line of the second motion trajectory in the east, south, west and north directions.
Specifically, when the target direction is the east, south, west, and north direction and the first simulation area is the rectangular area, the position information of the first simulation area, that is, the longitude coordinates of the boundary lines on the east-west side and the latitude coordinates of the boundary lines on the north-south side of the first simulation area may be determined.
The second motion track is a motion track of the target typhoon in a forecast time interval corresponding to a forecast time in the second forecast mode. The closed area determined by the tangent lines of the second motion track in the multiple target directions is a first area, and the first simulation area can be an area determined by expanding the first area outwards by a preset distance at the boundary line.
According to the embodiment of the application, the motion trail simulated by the low-resolution numerical mode in the forecast time interval corresponding to the forecast time of the target typhoon can be used for determining the simulation area in the high-resolution numerical mode taking the motion trail as a reference, namely, the target typhoon moves in the simulation area in the forecast time interval corresponding to the forecast time. Therefore, the simulation area of the target typhoon can be determined according to the specific condition (motion trail) of the typhoon, the forecasting time and the forecasting time interval, and a typhoon forecasting mode that the simulation area can be dynamically adjusted along with the forecasting time is realized.

Specifically, the typhoon message obtained at the forecast time includes all typhoons in a preset area at the current forecast time. The preset area is an area for typhoon release by a typhoon forecasting and early warning mechanism according to actual demand, and the area is larger than the target area. Specifically, the typhoon message further includes a position of each typhoon at the forecasting time, and according to the position of each typhoon at the forecasting time and the target area, the forecasting time and the typhoon number in the target area can be determined. If the typhoon number is zero, confirming that no typhoon exists in the target area at the forecasting time, namely, no target typhoon exists in the target area at the forecasting time, at the moment, determining that no typhoon can be forecasted at the current forecasting time, and waiting for the arrival of the next forecasting time. And if the typhoons are greater than or equal to 1, determining that any typhoon in the target area at the forecasting time is the target typhoons, and sequencing at least one target typhoons in the target area. Specifically, the typhoon message includes typhoon numbers of each typhoon, and the target typhoons in the target area can be ordered according to the typhoon numbers.
