摘要
高空测风业务是气象观测的基础业务之一,其数据广泛应于天气预报、气候研究、航空航天器等领域。L波段二次测风雷达、GPS测风和风廓线雷达是目前气象业务中最为广泛使用的三种测风方法。本文扼要介绍了这三种测风方法的原理,并基于观测数据对三种测风方法的结果进行了比对。比对结果表明:三种测风方法测得的水平风向误差在10度以内,水平风速误差小于1m/s,都能满足目前的业务要求,其中L波段二次测风雷达和风廓线雷达测风的结果更为接近。
The high-altitude wind business is one of the basic businesses of meteorological observation, whose data has been widely used in the research on weather forecast, climate, aerospace and other fields. The secondary L-band radar, GPS wind and wind profiler radar are the three most widely used methods in meteorological services. This paper briefly introduces the principle of the three wind methods, and the results of the observation data of the three wind methods are compared. The results show that errors in the horizontal direction under the three kinds of wind measurement are within 10 degrees, the horizontal wind speed error is less than 1m/s, which can meet the current business requirements, and especially the result measured by the secondary L-band radar and wind profile radar is more accurate.
