Abstract

The embodiment of the invention provides a method and a device for forecasting the proximity of convective weather based on multi-source observation data. The method comprises the following steps: obtaining multi-source observation data of pretreated convective weather; according to the multi-source observation data and the pre-trained prediction model, obtaining the generation and elimination evolution characteristics reflecting the real-time variation of the convective weather with time and space range; according to the generation and disappearance evolution characteristics and the prediction model, obtaining the neighboring prediction result of the convective weather. The apparatus performs the method described above. A method and apparatus for forecasting the proximity of convective weather based on multi-source observation data provided by an embodiment of the invention, the generation and disappearance characteristics of multi-source observation data of convective weather can beobtained by the prediction model, and the convective weather can be forecasted based on the generation and disappearance characteristics and the prediction model, so the generation and disappearance process of convective weather can be predicted effectively, and the convective weather can be forecasted accurately and effectively.

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...
