摘要
根据高空风探测的基本概念,建立站心坐标系和WGS-84地心坐标系,在两种坐标系中分别对高空风进行计算,并对计算结果进行比较。计算结果表明,对于传统的高空风探测,可仍然采用站心坐标系进行高空风的计算;对于GPS定位测风,可根据位置参数直接采用地心坐标系进行高空风的计算。
The methods of calculating upper winds in the WGS-84 and the station-origin coordinate system were given. The difference of the upper winds derived from the two methods was analyzed. The results showed that the upper winds could be calculated in the stationorigin coordinate system for the traditional sounding methods, but they should be directly calculated from the position parameters in the WGS-84 for the GPS sounding method.
