Upper air meteorological observations over northeastern Bangladesh in the south foot of Meghalaya Mountains

在2009年和2010年的季风季以及2010年和2011年的季风季，在孟加拉国的四个地点进行了同步密集的稀有探测仪观测活动。建立了高分辨率的上层探测数据集。利用这一资料，我们分析了孟加拉平原对流层大气环流的结构，以阐明梅加拉亚高原以南冷气团的存在，以及低层从南方来的湿空气的存在。南盟气象研究中心与STORM项目开展了强有力的合作，该中心为我们提供了一个大型数据集，其中包括邻近国家密集观测的结果。研究成果以论文和会议的形式呈现。

Synchronized intensive rawin sonde observation campaigns were conducted in four sites in Bangladesh in the monsoon season in 2009 and 2010 and the pre-monsoon season in 2010 and 2011. High resolution upper layer sounding dataset were constructed. Utilizing this dataset, we analyzed the structure of atmospheric circulation in the troposphere over the Bengal Plain, to elucidate the existence of the cold air mass just to the south of the Meghalaya Plateau, and the humid air inflow from the south in the lower layer. A strong cooperation was developed with the STORM project by the SAARC Meteorological Research Centre, which provided us a large dataset including results from intensive observations in adjacent countries. Research outcomes were presented in papers and conferences.
