Problems solved by technology

However, when the computer performs extrapolation based on the radar echo intensity, the state of the echo block changes all the time, such as changes in the echo intensity, the moving speed of the echo block, and the moving direction of the radar echo block in different areas. Push the results to cause different effects, and even affect the final output results

Abstract

The invention discloses an echo block tracking method and device of a radar echo image and a storage medium, and relates to the technical field of weather forecast, and the echo block tracking method of the radar echo image comprises the following steps: obtaining a plurality of radar echo images to form a radar echo image sequence, wherein a plurality of radar echo images in the radar echo image sequence come from the same radar and are arranged according to a time sequence; performing hierarchical division on each radar echo image in the radar echo image sequence to obtain a plurality of binarized hierarchical matrixes; determining all echo blocks in the hierarchical matrix according to a communication rule; calculating the similarity between echo blocks in the hierarchy matrixes of the same hierarchy of two adjacent radar echo images; and judging the two echo blocks with the similarity greater than a threshold as the same cloud cluster. By comparing the similarity of the echo blocks hierarchically, the echo blocks in the radar echo image can be accurately tracked.

Description

technical field [0001] The present invention relates to the technical field of weather forecasting, in particular to a radar echo image echo block tracking method, device and storage medium. Background technique [0002] Radar echo images are a powerful tool for meteorological stations to make short-term forecasts of severe convective weather, heavy rain and general precipitation. The radar echo image has the characteristics of intuitive image and quick timeliness to reflect the actual precipitation, which creates favorable conditions for meteorological stations to carry out short-term weather forecast services, and has received good results in practical work. When the radar electromagnetic wave encounters cloud droplets, raindrops, ice crystals and other particles during the propagation process, a part of the electromagnetic wave will be reflected back and received by the radar. The energy received by the radar is called the echo power, specifically for a certain part For ...
