Abstract

Embodiments of the present invention provide a method and device for convective weather nowcasting based on multi-source observation data, the method comprising: acquiring preprocessed multi-source observation data of convective weather; A forecast model is used to obtain the generation and consumption evolution characteristics reflecting the real-time changes of the convective weather with time and space; according to the generation and consumption evolution characteristics and the forecast model, the nowcasting results of the convective weather are obtained. The apparatus performs the method described above. The method and device for convective weather nowcasting based on multi-source observation data provided by the embodiments of the present invention obtains the generation and consumption evolution characteristics of multi-source observation data of convective weather through the forecast model, and based on the generation and consumption evolution characteristics and the forecast model Weather nowcasting can effectively predict the evolution process of convective weather generation and consumption, so that convective weather can be accurately and effectively nowcasted.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of weather forecasting, in particular to a convective weather nowcasting method and device based on multi-source observation data. Background technique [0002] Severe convective weather has the characteristics of strong localization, rapid development, and severe weather phenomena. It is often accompanied by lightning, hail, thunderstorms, strong winds, tornadoes, and heavy rainfall. It is extremely disastrous. However, how to improve its nowcasting level is a major challenge in the field of weather forecasting. [0003] In the domestic weather forecasting business, nowcasting usually refers to the forecast of 0-2 hours in the future. At present, extrapolation forecast based on a single data source, such as radar, satellite, lightning and other real-time data, is the main means of nowcasting. Existing extrapolation forecast algorithms based on weather radar data include TITAN (Thunde...
