tropospheric

Meantime, continuation of low tropospheric jet produces plentiful vapor for formation and continuation of rain gush.

同时，低空西南急流的维持，为暴雨的产生和维持提供了充足的水汽。

With the data of GPS meteorology network in Wuhan region, the article discussed the study of directly calculating precipitable water vapor with GPS zenith tropospheric delay.

本文针对武汉地区GPS气象网资料，进行了GPS对流层延迟直接推算可降水量的研究。
