摘要
针对现有高空气象探测雷达高空风计算方法中计算层间隔选取不完善的问题,提出了一种考虑测量随机误差传递的高空风计算方法。通过对高空风计算原理的分析,构建并简化了风速测量随机误差传递模型,由风速测量随机误差传递模型推导出秒数据滑动的动态计算层间隔计算公式,计算高空风风速和风向。利用该计算方法、59-701方法和1min间隔方法分别对实际探测数据进行计算验证,结果表明该方法具有更好的数据处理精度。
Aiming at the difficulty and imperfection of selecting the interval between the calculation intervals of the existing method of meteorological radar in calculating upper-air wind,the paper proposed the upper-air wind calculation method considering random error computation. Through the analysis of upper-air wind calculation principle,the paper constructed and simplified the random error transfer model in wind speed measurement,and with the application of dynamic calculation interval formula,upper-air wind speed and wind direction. The calculation method,59-701 interval method and 1min interval method were used respectively to calculate actual detection data for verification,which shows that the method has better precision of data processing.
