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.

在2009年和2010年季风季节以及2010年和2011年季风季节前，在孟加拉国的四个地点进行了同步密集的rawin探空仪观测活动。建立了高分辨率的上层探空数据集。利用该资料，分析了孟加拉平原对流层大气环流结构，阐明了梅加拉亚高原南部存在冷空气团，低层有来自南部的湿空气入流。与南盟气象研究中心的STORM项目建立了强有力的合作关系，该中心向我们提供了大量数据集，其中包括在邻国进行密集观测的结果。研究成果在论文和会议上作了介绍。
