According to the present invention, by viewing the weather information distribution map image, it is possible to visually know the positions of high pressure, low pressure, front and the like.

The best mode for carrying out the invention will be described below with reference to FIGS. FIG. 1 is a system configuration diagram according to the best mode for carrying out the present invention. In the figure, reference numeral 1 denotes a weather information server that provides weather information. Reference numerals 11 and 12 denote communication control units and data processing units that operate in the weather information server 1, and 13 denotes a hard disk in the weather information server 1. The weather information server 1 is connected to a weather service support center 3 via the Internet 2. A personal computer 4 is connected to the weather information server 1 through the Internet 2.

In the hard disk 13 in the weather information server 1, a white map image file 13a of the whole country or an area including the position of the weather observation point is prepared in advance.

Next, the data receiving means 11a from the weather service support center of the communication control unit 11 in the weather information server 1 receives the weather observation data transmitted by the weather service support center 3 at regular time intervals via the Internet 2. The received data is stored in the weather data table 13b in the hard disk 13. Subsequently, the maximum value calculation means 12a of the data processing unit 12 performs processing according to the flowchart of FIG. First, step S101 indicates that processing in a loop is performed for all data in the weather data table 13b.

In the processing in the loop, in step S102, if the meteorological data is equal to or less than the minimum value so far, the processing in step S103 is performed to set the data to the minimum value. Next, in step S104, if the meteorological data is equal to or greater than the maximum value so far, the data is set to the maximum value by performing the process of step S105.

Subsequently, the weather information distribution map image creation means 12b performs processing according to the flowchart of FIG. First, in step S201, it is shown that the processing in the loop is performed for all data in the weather data table 13b.

In the processing in the loop, in steps S202, S204, and S206, the meteorological data is compared with the minimum value calculated by the maximum value calculation means 12a, and as a result, in any of the processing in S203, S205, and S207. A different color is assigned for each unit of the value, that is, 1 hectopascal if the weather data is atmospheric pressure, and 1 degree if the temperature is air temperature. If the number of colors assigned to the process in advance is exceeded, the weather data is compared with the maximum value calculated by the maximum value calculation means 12a in steps S208, S210, and S212, and as a result, S209, In one of the processes of S211 and S213, one unit of the value, that is, 1 hectopascal if the weather data is atmospheric pressure, and a different color every 1 degree if temperature is assigned. In step S214, the meteorological data is plotted on the white map 13a using the color thus determined. In the flowchart of FIG. 3, green and red are specifically shown as color names, but the same effect can be obtained with other colors.

After the process in the loop is completed, the completed map is stored in the weather information distribution map image file 13c in step S216. FIG. 4 shows an example of a weather information distribution map image. In this example, the last three digits of the numerical value representing the atmospheric pressure at each point in 0.1 hectopascal units are displayed. For example, “306” near the center indicates 1030.6 hectopascals, and by applying the present invention, this point is the darkest color, and “310”, “311”, “313” in the vicinity thereof indicate 1031 hectopascals, It becomes the second darkest color, and the presence of low pressure is visually clarified.

Next, when the user browses the weather information distribution map image, the user PC 4 activates the browser 41 for browsing the home page, whereby the httpd 11b of the communication control unit 11 causes the weather information distribution map image file to be displayed. 13c is transmitted to the user personal computer 4.

The operation of the maximum value calculation means 12a of the data processing unit 12 can be as shown in the flowchart of FIG. In this case, first, step S301 indicates that the processing in the loop is performed for all the data in the weather data table 13b.

In the processing in the loop, in step S302, if the meteorological data is equal to or less than the minimum value up to that point, the processing in step S303 is performed to set the minimum value so far as the second minimum value and the data as the minimum value. . In step S304, if the data is equal to or less than the second minimum value, the data is set to the second minimum value by the process of step S305. Next, in step S306, if the meteorological data is greater than or equal to the maximum value so far, by performing the processing in step S307, the maximum value so far is set as the second maximum value, and the data is set as the maximum value. In step S308, if the data is greater than or equal to the second maximum value, the data is set to the second maximum value by the process of step S309.

If the difference between the minimum value and the second minimum value is 1 unit after the processing in the loop is completed, that is, if the weather data is atmospheric pressure, it is 1 hectopascal, and if the temperature is greater than 1 degree, it is step S312. The second minimum value minus 1 unit is the minimum value. In step S313, if the difference between the maximum value and the second maximum value is 1 unit, that is, 1 hectopascal if the weather data is atmospheric pressure and greater than 1 degree if the temperature is air temperature, the second maximum is determined in step S314. Value plus 1 unit is the maximum value. By performing the weather information distribution map image creating means 12b after performing this processing, even if the minimum value or the maximum value is far from other values, it is possible to plot with continuous colors on the weather information distribution map. .

When a color is selected according to the value of the wind direction as an example of the weather data 13b, the operation of the weather information distribution map image creating unit 12b can be as shown in the flowchart of FIG. In this case, first, step S401 indicates that the processing in the loop is performed for all data in the weather data table 13b.

In the process in the loop, if the weather data is “north” in step S402, the process of step S403 is performed and a predetermined reference color is assigned to the data. If the meteorological data is “north-northeast” in step S404, the process of step S405 is performed to assign a hue color 22.5 degrees away from the reference color. Thereafter, the same processing is performed up to steps S410 and S411, and the weather data is plotted on the white map 13a using the color thus determined in step S412.

After the processing in the loop is completed, the completed map is stored in the weather information distribution map image file 13c in step S414.

The system block diagram concerning the best form for implementing this invention is shown. The flowchart explaining operation | movement of a calculation means, such as a maximum value, is shown. The flowchart explaining operation | movement of a weather information distribution map image preparation means is shown. An example of a weather information distribution map image is shown. 3 is a flowchart for explaining the operation of the maximum value calculation means in the first embodiment.
