Abstract

The embodiment of the invention discloses a tropical cyclone precipitation and non-tropical cyclone precipitation separation method and equipment and a storage medium. The method comprises the steps of acquiring information of a tropical cyclone event, wherein the information of the tropical cyclone event comprises the central position of tropical cyclone, the air pressure of the tropical cycloneand rainfall grid data; dividing the precipitation grid data into an inner ring area, an outer ring area and a transition area according to the central position of the tropical cyclone and the air pressure of the tropical cyclone; acquiring a growth starting region, and performing neighborhood connection operation by taking the growth starting region as a starting point and taking a preset size asan operation unit to obtain a connection result; dividing annular regions from inside to outside by taking the central position of the tropical cyclone as a circle center, calculating precipitation in each annular region, and obtaining a tropical cyclone precipitation attenuation range according to the precipitation in each annular region; and obtaining tropical cyclone precipitation and non-tropical cyclone precipitation. According to the method, tropical cyclone precipitation and non-tropical cyclone precipitation can be accurately separated, and powerful support is provided for researchingtropical cyclones.

Description

technical field [0001] The invention relates to the field of meteorological research, in particular to a method, equipment and storage medium for separating tropical and non-tropical cyclone precipitation. Background technique [0002] Tropical cyclone refers to the general term of non-frontal vortex with organized convection and definite cyclonic circulation generated on tropical or subtropical ocean surface, including tropical depression, tropical storm, severe tropical storm, typhoon, strong typhoon and super strong typhoon. my country is on the brink of the Northwest Pacific Ocean and the South China Sea, and is one of the major countries severely affected by tropical cyclones. [0003] Tropical cyclone precipitation is a smooth, continuous, spatially integrated indicator that can explain all potentially important aspects of tropical cyclone activity (such as frequency, intensity, duration, etc.). Therefore, obtaining reliable tropical cyclone precipitation data is of ...
