dropsonde

The dropsonde system incorporates various sensor instruments, data system and software for telecommunications and data storage.

下投系统由测量器、数据收发系统和信号软件等部分组成。

The vertical velocity is calculated directly from the raw dropsonde data, it is a preliminary attempt to use the vertical velocity for synoptic analysis.

垂直气流速度是根据探空落速变化算出,把它用在天气系统分析是试。
