dropsonde

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

下投由测量器、数据收发和信号处理软件等成。

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,把它用在天气析是初次尝试。
