| Research Abstract |
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.
