摘要
对西昌发射场L波段雷达、风廓线雷达和GPS测风数据进行对比分析,对不同季节、不同风速条件、不同高度下的风向和风速数据进行相关性分析,结果表明:发射场干季风速数据相关性较高,风向数据相关性较低,雨季风速数据相关性较低,风向数据相关性较高;随风速变大,L波段雷达和GPS测风的数据相关性越来越高,二者与风廓线雷达测风数据的相关性明显变低;在各高度层风向相关性均较高,在低层风速相关性较低,在中高层风速相关性较高。
Comparison and analysis are conducted among L-band radar,wind profile radar and GPS wind-measuring data of Xichang Satellite launch site by various seasons,various levels of wind speed and height. The results indicate that the correlation of wind speed is higher in dry season than in rainy season. On the contrary,the correlation of wind direction is lower in dry season. Also,the correlation of wind direction is high in various levels of height,and the correlation of wind speed is higher in higher height. Besides,the correlation between L-band radar and GPS wind-measuring data gets higher with wind speed increasing,but the correlation between wind profile radar and both of them gets lower with wind speed increasing.
