4.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仪落速变化算出,在天气系统分析是初次尝试。
5.We introduce a modified model approach to estimate the unique synoptic oceanic wind field from backscatter of spaceborne scatterometer.
