However , these conditions lie in boundary level above ground with small scales , and the general surface and rawinsonde data can not reveal them 触发条件通常位于近地面层中，水平尺度也很小，常规资料无法揭示出来。
2.
Then cloud motion winds are derived from these tracers and after a circumfluence analysis on the cloud motion winds , the cloud motion winds are compared with the rawinsonde winds 对用该方法选取的示踪云进行云迹风反演，然后对反演出的云迹风进行环流分析，并与探空风进行比较。
