初夏孟湾风暴造成云南连续性强降水的中尺度分析

Mesoscale analysis of Yunnan successive heavy precipitation caused by storms over the bay of Bengal in the early summer

结果表明：初夏孟湾对流云团活动对低纬高原的初夏降水有明显影响；

Evidences show that the Low Latitude Plateau ( LLP ) rainfall is affected by the activity of convective cloud clusters to a great extent during the early summer .

孟湾风暴水汽的前向追踪结果表明，风暴水汽经中南半岛进入中国云南，可输送至长江中下游。

Moisture forward tracking indicates that the water vapor of storms enters Yunnan via the Indochina peninsula and then is transported into the mid and lower reaches of the Yangtze River .

结果表明：孟湾风暴在孟加拉湾海域生成后，生命史一般为2～3天，风暴云团云顶亮温低于-65℃；

The results show that the life of the storm over the Bay of Bengal is 2 or 3 days and the cloud-top temperature of the storm is always below – 65 ℃ .

利用常规气象资料、物理量场、卫星云图和多普勒雷达资料对孟湾风暴影响下云南初夏出现的4次连续性强降水天气过程的中尺度特征及其环流背景条件进行了分析。

By using regular meteorological data , physical quantity fields , satellite imagery and Doppler radar echo data , we analyze the mesoscale features and the conditions of 4 successive heavy precipitation processes in Yunnan caused by storms over the Bay of Bengal in the early Summer .
