Abstract

The invention provides a rainstorm identification method and device based on a multi-model fusion convolutional network, and relates to the technical field of rainstorm early warning. The method comprises the steps: obtaining sample Doppler radar base data of a to-be-identified region, and determining the attribute information of a storm body contained in the sample Doppler radar base data based on the sample Doppler radar base data; obtaining observation data of the to-be-identified area sent by the ground observation station, and constructing a data set based on the observation data and the attribute information; inputting the data set into a multi-model fusion convolutional network, and training and optimizing the multi-model fusion convolutional network to obtain a rainstorm identification model; and obtaining the current Doppler radar base data of the to-be-identified area, and and determining whether the rainstorm occurs in the to-be-identified area by using the current Doppler radar base data and the rainstorm identification model. Thus, the technical problem of low identification accuracy of an existing rainstorm identification method is solved.

Description

technical field [0001] The invention relates to the technical field of rainstorm design, in particular to a rainstorm identification method and device based on a multi-model fusion convolutional network. Background technique [0002] Heavy rain is one of the types of severe convective weather and is a kind of bad weather. Its formation process is quite complex. Generally speaking, from the macroscopic physical conditions, the main physical conditions for the production of heavy rain are the abundant and continuous water vapor, strong and persistent airflow upward movement and the instability of the atmosphere structure. Heavy rains have different negative impacts on many industries. For example, heavy rains may damage soil and vegetation farms, affect people's normal travel, and be prone to floods and waterlogging. Therefore, the monitoring and early warning of bad weather such as heavy rain is very necessary. However, it is also one of the more difficult problems in meteor...
