Problems solved by technology

[0003] 1. Although there have been a large number of studies on heavy rainfall in warm regions, previous studies mainly focused on individual case analysis, and there are few studies on the distribution characteristics and synoptic background of heavy rainfall in warm regions as a whole;
[0004] 2. Subjective methods are used to identify and classify heavy rains in warm regions, but subjective methods are time-consuming and laborious, accompanied by manual errors, which do not meet the requirements of modern informationization and intell

Abstract

The invention relates to the field of weather, in particular to a warm area rainstorm identification and classification method and system, and the method comprises the steps: obtaining weather grid point data of a set time period in a preset geographic range; judging and identifying the rainstorm of the warm area through a preset identification model; and classifying the rainstorm of the warm areaaccording to the weather circulation background. According to the invention, the rainstorm of the warm area is identified and classified according to the weather background when the rainstorm of thewarm area occurs, which is beneficial to discussion of the overall distribution characteristics and climate characteristics of the rainstorm of the warm areaI. In addition, the weather condition or model when the rainstorm of the warm area occurs is mastered, and the rainstorm of the warm area when the same or similar circulation background occurs next time is relatively well predicted, so that the prediction accuracy of the rainstorm of the warm area can be improved; not only is a large number of resources saved, but also convenience and quickness are achieved.

Description

technical field [0001] The invention relates to the field of meteorology, in particular to a method and system for identifying and classifying heavy rain in warm regions. Background technique [0002] Generally speaking, rainfall is produced by the intersection of cold and warm air masses, and is the product of the interaction of multi-scale weather systems under the background of favorable large-scale circulation. South China is located in a low-latitude region, and its precipitation activities are jointly affected by the low-latitude system and the mid-high latitude system. It is the region with the largest average annual rainfall, the largest number of rainstorms, and the longest flood season in China. The rainy season of the flood season starts from April and ends in September. Precipitation presents an obvious double-peak structure, mainly convective precipitation. Among them, heavy rain in the warm area of ​​South China is a major feature of heavy rain in South China....
