Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a weather forecast server, a portable electronic device, and a program for collecting and analyzing weather information and performing weather forecast from the information.
[0002]
[Prior art]
The weather forecast is performed by performing a numerical forecast with a computer based on weather information (atmospheric pressure, temperature, humidity, wind direction, wind speed, illuminance, etc.) sent from each weather observation point. This numerical forecast is a method of inputting weather information for each time into a predetermined equation and predicting a future atmospheric state by a supercomputer. More specifically, first, the entire earth is covered with a grid network at predetermined intervals, and weather information at each grid point is obtained. At this time, if there is no device for measuring the weather information at the grid point, the weather information is calculated from the weather information at surrounding grid points. When the weather information of each grid point is obtained, the weather information is input to a predetermined equation to calculate future weather information. The program used for the calculation of the numerical forecast is called “numerical forecast model”.
[0003]
The accuracy of weather forecast by the above numerical forecast model depends on grid spacing. Normally, numerical forecasts provided by the Japan Meteorological Agency are calculated based on weather information of equally-spaced grid points provided on a global scale, so that local weather forecasts are difficult. This is because even the smallest grid has a wide area of about 30 km on each side (for example, the area where the area between Tokyo and Kawasaki can be entered), so it is difficult to predict local weather such as “Shinjuku” and “Ginza”. is there.
In addition, the numerical forecast provided by the Meteorological Agency and the like is calculated only twice a day, and thus is not useful when the course of a typhoon changes every moment, such as during a typhoon season.
[0004]
As a weather forecast system for solving the problems of the conventional weather forecast as described above, for example, a user of a plurality of weather information observes the weather information at its own position, and the weather information is transmitted from an information terminal. A system has been proposed in which a server is provided via a communication line, and the server records weather information transmitted from an information terminal, creates weather map data and the like at a predetermined timing, and publishes the data (for example, Patent Document 1). 1).
In addition, a mobile phone scattered over a wide area and connectable to the Internet transmits weather information indicating a weather state of a location where the mobile phone is located to a server, collects the weather information, and edits and processes the weather information as weather information of a predetermined area. Accordingly, a weather information providing system that transmits the edited and processed weather information to a requesting user has been proposed (for example, see Patent Document 2).

[0006]
[Problems to be solved by the invention]
However, when performing local weather forecasting by numerical forecast, weather information must be arranged at each grid point and calculated, but in Patent Documents 1 and 2, it does not necessarily correspond to all arrangement positions. Since there is no guarantee that the weather information can be obtained from the place, it has been difficult for such a system to make accurate weather forecasts based on numerical forecasts.
