台湾海峡850hPa低空急流天气气候特征的初步分析

An initial analysis of weather climate features of low-level jet stream at 850hPa in Taiwan Strait

本文应用任意3a中850hPa上的风及500hPa和地面气象资料，对台湾海峡地区出现低空急流的天气气候特征，形成急流的天气背景及其影响下的天气进行初步分析。结果表明，台湾海峡地区850hPa低空急流具有明显的季风特征和特定的地理影响。

The wind data in any three years at 850hPa and 500hPa and ground weather data are used for the initial analysis of the low-level climatic charaters of weather,the weather background that forms the jet-stream and the weather under their infIuences is the Taiwan Strait.The results indicate that the low-level jet stream at 850hPa in the Taiwan Strait has distict monsoon features and is sub jet to specific local geographic impacts. The conclusion is meaningful for weather forecasting in the Taiwan Strait.
