Abstract

The invention relates to a typhoon forecasting method and system, a readable storage medium and equipment, and belongs to the technical field of weather. Global forecasting data of a preset time pointis acquired, a vortex recognition system is mainly adopted for recognizing the global forecasting data and can recognize a vortex structure formed by typhoon, and typhoon path information and intensity information of the global forecasting data can be recognized within a shorter time to achieve typhoon forecasting. According to the method, the vortex recognition system can firstly recognize the typhoon and then acquire typhoon data, compared with a traditional mesoscale numerical forecasting mode, calculation amount of weather forecasting is greatly reduced, the processing time of typhoon forecasting in the earlier stage is greatly shortened, releasing of typhoon forecasting can be accelerated, the global forecasting data of higher accuracy can be fully utilized as far as possible, and the accuracy of typhoon forecasting is improved.

Description

technical field

[0001] The invention relates to the field of meteorological technology, in particular to a typhoon forecasting method, system, readable storage medium and equipment. Background technique

[0002] The development of numerical forecasting models has made it possible to forecast the track, intensity, precipitation, and structure of wind direction and speed of typhoons. Traditional typhoon forecasting systems generally rely on mesoscale numerical forecasting models.

[0003] In the case of ignoring the correction modules that vary with different forecast systems such as data assimilation, the traditional typhoon forecast system mainly uses the mesoscale numerical forecast model to process the global forecast data of the weather system and forecast typhoon information; weather The data of the system information can generally provide a forecast of more than 10 days, but the accuracy of the forecast information gradually decreases with the forecast period.
