Radar and mesoscale meteorology analysis was conducted on a rainfall taken place on September 5 2003 by using Doppler radar data and mesoscale numerical weather forecast model products.

Imminent and short-term forecast of regional debris flow and its application:a forecasting system based on Doppler weather radar technology;

Design of a Doppler Weather Radar Second Production Process System;

Development of the signal processor of an X-band Doppler weather radar;

Method of inverting mesocyclone circumfluence field with a single Doppler radar;

Doppler radar plays important roles on monitoring and predicting downbursts for its high temporal and spatial resolution.

By using Doppler radar measurements and the hour-to-hour rainfall data from automatic weather stations, the radar echo cells corresponding to the short-range local torrential rainfall occurred in summer(June to August) 2004 in Beiji.

Developed is a new system for real time processing weather Doppler radar data operating on the PC Model 486.

This paper introduces the monitoring of local short-time rainstorm and the element evolution of Zuoyun meteorological sites,and analyzes the weather trend,refined observational data and Doppler radar data.

The ensemble Kalman filter (EnKF) is applied to assimilation of simulated Doppler radar data in a cloud model and its performances under different conditions are investigated.

With an ultimate goal of operational application of Doppler radar data in numerical weather prediction (NWP), a primary Doppler radar data analysis and assimilation system using three-dimensional variational (3DVAR) and Ensemble Kalman Filter (EnKF) techiques has been constructed.

This paper introduces an X band Doppler weather radar receiver, expound the design idea of the receiver channels and the high-pure spectrum signal source on the characteristics of weather target echo signal,and the results of experiments are also presented.
