Convection development identification method based on networking wind profile radar

Abstract

The invention provides a convective development identification method based on networking wind profile radars, and relates to the technical field of weather forecast, the convective development identification method based on networking wind profile radars comprises the following steps: S1, networking wind profile radars: firstly screening the wind profile radars for networking, the number of the networking wind profile radars being four or more; according to the method, atmospheric power parameters such as divergence, vorticity, wind shear and vertical speed with higher spatial-temporal resolution can be inverted by utilizing mesoscale net observation of the wind profile radar, atmospheric vertical power change characteristics before convection triggering can be more accurately captured, divergence and vorticity distribution of a real-time three-dimensional space can be obtained, and the real-time vertical power change characteristics can be obtained. According to the method, weather predictors can understand the fine structure of a weather system and quickly find a strong rising motion area, the method is used for short-time nowcasting of heavy rainfall, important reference is provided for severe convection weather monitoring and early warning and short-time nowcasting, practicability is high, and progress is remarkable.

Description

technical field [0001] The invention relates to the technical field of weather forecasting, in particular to a method for identifying convection development based on a networked wind profile radar. Background technique [0002] Strong convective weather is a weather phenomenon caused by the strong vertical movement of the atmosphere. It has strong destructive power and is often accompanied by disasters such as heavy precipitation, strong winds and thunderstorms. For example, short-term heavy precipitation and convective strong winds are typical strong convection. Weather, weather radar using Doppler and phased array technology can effectively monitor it. At present, combined with professional theories and methods, it can analyze the spatial location, moving speed and development trend of storms, as well as the intensity of strong winds or precipitation, etc. There is a lot of valuable weather information, but there is still no effective prediction method for the occurrence a...
