Analysis of Satellite Cloud Image and Radar Echo Features of a Strong Squall Line Weather

一次强飑线过程的卫星云图及天气雷达回波特征分析

A new distortionless method for compressing digital weather radar echo images is proposed.

提出一种数字化天气雷达回波图象的无失真压缩方法。

Usually, conventional incoherent weather radar is used to provide only the information on the position of a weather target and its radar reflectivity by detecting echo intensity.

通常非相干的常规天气雷达的应用仅仅是通过雷达回波强度的探测来提供天气目标物的位置和其反射率的信息。

Based on the echo data of the Yichang WSR-98D S-band Doppler weather radar, a severe storm with 28.8 m · s-1 maximum instantaneous wind speed at the Three Gorge Dam Area on 2 July 2001 is analyzed.

利用宜昌多普勒天气雷达回波资料，分析了2001年7月2日发生在三峡坝区瞬间极大风速达28.8m·s-1的强对流风暴。

By using the Doppler radar echo about Base Reflectivity ( R), Storm Relative Vel Map ( SRM), Vert Integrated Liquid ( VIL) etc, a severe hail and wind weather process which occured in the south of North China on June 20,2004 is analyzed.

运用多普勒雷达的基本反射率（R）、风暴相对径向速度（SRM）、垂直积分液态含水量（VIL）等产品，分析了2004年6月20日华北南部罕见的冰雹大风天气过程。
