Meteorological detection method and system of three-dimensional wind field

Abstract

The invention relates to a meteorological detection method and system of a three-dimensional wind field. The meteorological detection method comprises the steps that each phased array weather radar detects an instruction according to a receiving mode, and scans an equilateral-triangle-shaped detection area at the same time; the intensity data and the velocity data which are obtained through scanning are sent to a control processing center; the intensity data is fused to obtain a reflectivity factor, and meanwhile, the velocity data is subjected to vector synthesis to obtain a velocity vector field; according to the reflectivity factor and the velocity vector field, the three-dimensional wind field is determined; the position where microburst occurs is detected in the three-dimensional windfield. The invention further provides the system. The system comprises the three phased array weather radars and the control processing center. The equilateral-triangle-shaped detection area is builtthrough the meteorological detection method, and a weather radar detection area is synergistically detected to obtain the data, so that it is achieved that whole-airspace meteorology targets in an observation space range are accurately detected, and the more precise three-dimensional wind field is generated to greatly improve an existing meteorological observation level.

Description

technical field [0001] The invention belongs to the field of weather radar detection, and in particular relates to a three-dimensional wind field meteorological detection method and system. Background technique [0002] Weather radar is an effective tool that can effectively observe various strong weather phenomena, but the traditional weather radar has the following deficiencies: ① Due to the influence of the curvature of the earth, weather radar is limited in the observation of near-surface cloud and rain targets when observing at a relatively long distance. At the same time, there is no detection data above an elevation angle of 30 degrees, and there are a large number of blank detection areas at short distances; ② Existing radars use mechanical rotation scanning, and the beam scanning speed is relatively slow. The time to complete a volume scan is about 6 minutes, and the time resolution is low. It is difficult to capture rapidly generated and developing small-scale weat...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing observation method loses the meteorological target information in space, especially for meteorological targets such as fast-changing wind field and micro-downstroke weather, it is impossible to obtain the meteorological information of the complete space within the observation range in time target information, resulting in a decrease in meteorological data acquisition rate and data quality, which cannot fully meet the application requirements of meteorological research and meteorological support
