Abstract

The invention discloses a mountainous area rainstorm monitoring method which comprises the following steps: satellite data and precipitation data of a ground base station and an automatic station areacquired; preprocessing the satellite data to obtain a satellite image and satellite resource data; processing the satellite image to obtain a mountainous rainstorm cloud cluster image; processing themountainous area rainstorm cloud cluster image based on the satellite resource data, and identifying a mountainous area rainstorm cloud cluster; automatically tracking and forecasting the rainstorm cloud cluster in a mountainous area; establishing a satellite quantitative precipitation estimation model based on the satellite resource data and the precipitation data of the ground base station andthe automatic station, and performing quantitative precipitation estimation on the forecasted mountainous rainstorm cloud cluster according to the satellite quantitative precipitation estimation model. According to the method disclosed in the invention, rainstorm monitoring of remote mountainous areas can be realized.

Description

technical field [0001] The present application relates to the technical field of atmospheric monitoring, in particular to a method for monitoring rainstorms in mountainous areas. Background technique [0002] Heavy rain can cause natural disasters such as floods, landslides, and mudslides. Therefore, it is necessary to accurately forecast and prevent rainstorms in order to avoid or mitigate a series of natural disasters. Predicting the rainstorm needs to observe the rainstorm cloud cluster in the sky. By accurately identifying the location and range of the rainstorm cloud cluster, the location and range of the rainstorm can be further predicted, so as to realize monitoring. [0003] The existing technology generally uses Doppler radar to realize the observation of a specific area, and the observation image and related data of the corresponding area will be output at a fixed period, so as to realize the prediction of heavy rain. [0004] However, the applicant of the present...
