Problems solved by technology

At present, most of the radars used for network observation of X-band weather radars are dual-polarization Doppler weather radars, which have a large amount of data, many quality control processes, and time-consuming data transmission and quality control. show application
There is a large lag, which is not conducive to reflecting the fine and fast business advantages of the X-band radar network, and is not conducive to the monitoring, early warning and forecasting of strong convective weather

Abstract

The invention discloses an X-band weather radar network data processing method, including step 1, establishment of an X-band weather radar network data processing system; step 2, volume scanning: each X-band weather radar scans the obtained radial data Real-time transmission to the X-band weather radar network data processing system of the central station with the root as the unit; Step 3, data reception: the data receiving module copies the received layer 360 radial data into the quality control module; at the same time, clears the corresponding data Buffer area; step 4, quality control; step 5, generation of quality control base data files; step 6, product generation. The invention shortens the time for X-band sky radar data transmission and quality control, improves the timeliness of data from radar terminal to product generation and user use, and brings many conveniences to the monitoring, early warning and forecasting of strong convective weather.

Description

technical field [0001] The invention relates to a method for processing weather radar network data, in particular to an X-band weather radar network data processing method. Background technique [0002] Severe convective weather includes short-term heavy precipitation, thunderstorms and strong winds, hail, lightning, tornadoes, etc. It is a type of high-impact disastrous weather that develops rapidly, is highly localized, and is highly destructive. By emitting electromagnetic waves, weather radar can observe the internal three-dimensional structure and evolution characteristics of strong convective systems, and is currently the most effective means of strong convective monitoring. At present, the average distance between the radars of the new-generation weather radar operational observation network is 200 km. Due to the influence of the curvature of the earth, the widening of electromagnetic wave beams with distance, and terrain occlusion, the coverage rate for low layers (&...
