Embodiment

[0270] The Bayannaoer area of ​​Inner Mongolia is located in the north of my country, and strong convective weather often occurs in summer, and hail is one of the main disastrous weathers affecting local production activities. According to the statistical results of the hail observation test in the Bayannaoer area, in 2020, there were 22 days of hailstorms, and the largest hailstone observed on the ground had a diameter of more than 40mm, which had an extremely bad impact on local economic production and travel activities.

[0271] From 18:50 p.m. to 19:10 p.m. on July 25, 2020, multiple hailstorms occurred. According to the information recorded by the observers at the local operation station, the hailstorm lasted for more than 20 minutes, and the maximum diameter of hailstones on the ground was 3cm. Serious economic losses were caused. Table 1 shows the conditions of hail on that day:

Abstract

The invention relates to the field of weather forecast and the field of informatization data processing, and provides a hail cloud early recognition method and a storage medium. The objective of the invention is to perform early warning in the early stage of hail and improve the accuracy of early recognition of hail cloud. According to the main scheme, the method comprises the steps: 1, after weather radar data are selected, primarily selecting the detection data according to radar data time; 2, performing hail cloud monomer identification according to the reflectivity data of the radar data, and determining a target longitude and latitude range according to a hail cloud monomer identification result; 3, screening detection data by using a longitude and latitude range, and excluding data not in the longitude and latitude range; 4, calculating each judgment factor in the longitude and latitude range of the single body according to the matched detection data, comparing a judgment result with a hail cloud judgment threshold value, determining a hail cloud single body, and displaying a hail cloud outline schematic diagram on an interface.

Description

technical field [0001] The invention relates to the field of weather forecast and the field of information data processing, and provides a hail cloud early identification method and a storage medium. Background technique [0002] Hail clouds and other thunderstorm clouds (thunderstorm clouds or weak convective clouds) belong to strong convective weather. Compared with strong convective clouds, weak convective clouds generally have a short life cycle due to their weaker development, and the range of cloud bodies is small. The wave intensity is weak, and lightning and precipitation are rarely formed, so it is easier to identify. However, there are many similarities in the development process of hail clouds and thunderstorm clouds, and it is difficult to distinguish early. In the past, due to the limitation of detection means, it was difficult to understand the microphysical change process in the cloud in real time, so the problem of early identification of hail cloud has not b...
