In the embodiment of the present application, the forecast time period and the target area need to be set in advance. The forecast time period is a time period in which typhoon forecast is needed, and includes an initial time and a termination time, specifically, the forecast time period can be determined by directly setting the initial time and the termination time, or the forecast time period can be determined by setting a first forecast time, a last forecast time, a duration of each forecast, and a time interval between two adjacent forecast 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.
A plurality of forecast moments are arranged in the forecast period, wherein the plurality of forecast moments can be arranged at equal intervals or unequal intervals, the number of the forecast moments in the forecast period can be determined according to actual forecast requirements, the frequency of forecasting, the intensity of the target typhoon in the target area and the like, and the application is not particularly limited. And acquiring a typhoon message corresponding to the forecast time at each forecast time. Specifically, the typhoon message is issued by a typhoon forecast warning mechanism, and can be used as a basis for judging whether typhoon exists in the target area. In the forecasting period, the typhoon simulation area determining system can start to detect from the starting time of the forecasting period, and when the forecasting time is detected to arrive, the typhoon message at the current time, namely the typhoon message at the forecasting time, is obtained from the message issued by the 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 where typhoon distribution is required by a typhoon forecasting and early warning mechanism according to actual requirements, and the area is larger than the target area.
And step 102, determining at least one corresponding target typhoon in the target area according to the typhoon message.
And the typhoon message acquired at the forecast time comprises all typhoons in a preset area at the current forecast time. By the typhoon message, the typhoon condition in the target area can be determined, and specifically, the number of typhoons and the number of each typhoon can be determined. When the typhoon number is larger than or equal to 1, any typhoon in the target area is the target typhoon.
The typhoon amount in the target area can be determined according to the typhoon message, and after the target typhoon in the target area is determined, first forecast information of the target typhoon in a first forecast mode in a forecast time interval corresponding to the forecast time can be further acquired, so that a first simulation area of the target typhoon in the forecast time interval with the forecast time as the starting time can be determined. The first simulation area is used for simulating the area of the target typhoon in the first forecasting mode within a forecasting time interval corresponding to the forecasting time.
Specifically, for each forecast time, a corresponding forecast time interval may be set, where the forecast time interval is smaller than the forecast time interval, the starting time of the forecast time interval is the forecast time, and the ending time of the forecast time interval is determined according to the length of the forecast time required at this time. The length of the forecast time interval may be determined according to the typhoon number and/or typhoon intensity at the current forecast time, which is not specifically limited in the present application.
According to the method and the device, the position and the coverage range of the simulation area of the target typhoon in the forecasting time period can be dynamically adjusted according to the actual typhoon condition and the forecasting time period of the forecasting time period by acquiring each forecasting time and the simulation area of each target typhoon in the target area in the forecasting time period corresponding to the forecasting time. Compared with the situation that the position and the coverage range of the simulation area are not changed all the time in the forecast time period, the time consumed by forecast calculation can be reduced, and the waste of storage space is avoided.

It should be noted that the second forecast information corresponding to the target typhoon in the second forecast mode can be directly obtained from the corresponding system using the second forecast mode according to the typhoon number of the target typhoon. The second prediction information includes a second motion trajectory of the target typhoon in a prediction time interval corresponding to the prediction time, and under the condition that the second prediction information of the target typhoon corresponding to the second prediction mode is known, the first prediction information can be determined according to the resolution of the first prediction mode and the second prediction information, and the first prediction information is the prediction information of the target typhoon in the first prediction mode.
According to the embodiment of the application, when first forecast information of the target typhoon in the first forecast mode in the forecast time interval corresponding to the forecast time is obtained, second forecast information of the target typhoon in the second forecast mode and the resolution of the first forecast mode are obtained, and the first forecast information can be determined. Therefore, the calculation process can be simpler, and the accuracy of typhoon forecasting can be ensured.

According to the embodiment of the application, the simulation area in the high-resolution numerical mode with the motion trajectory as the reference can be determined by the motion trajectory simulated by the low-resolution numerical mode in the forecast time interval corresponding to the forecast time of the target typhoon, that is, 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), the forecasting time and the forecasting time interval of the typhoon, and the typhoon forecasting mode that the simulation area can be dynamically adjusted along with the forecasting time is realized.

Specifically, the typhoon message further includes a position of each typhoon at the forecasting time, and the forecasting time and the number of typhoons located in the target area can be determined according to the position of each typhoon at the forecasting time and the target area. If the typhoon quantity is zero, it is determined that there is no typhoon in the forecast time and the target area, that is, there is no target typhoon in the forecast time and the target area, at this time, it can be determined that there is no typhoon at the current forecast time, and then the next forecast time is waited to arrive.

Specifically, the typhoon message includes a typhoon number of each typhoon, and the target typhoons in the target area may be sorted according to the typhoon number.
