Abstract :

Atmosphere as varied and vast as the universe itself is a natural phenomenon all pervasive. The process of atmospheric studies has been there ever since the existence of human race. From ancient times when men were living in caves looked up at the skies in anticipation till the modern times of prediction, atmosphere continues to be an area of serious studies and boundary layer knowledge is important in atmospheric related studies. With the same spirit, the present paper attempts a �Study of Atmospheric Boundary layer characteristics over West Coastal Mega City in India.�� This paper is concerned with the study of atmospheric boundary layer characteristics during South-West Monsoon in the selected mega city. The study is done by taking the surface data and upper air data collected from Indian Meteorological Department. In surface data analysis, meteorological parameters such as temperature, relative humidity, wind speed and wind direction are taken to study the said characteristics and the same meteorological parameters profiles are used for upper air data analysis . Also the study of specific characteristics of atmospheric boundary layer during North-East Monsoon. The surface and upper air data of the selected mega city obtained from Indian Meteorological Department is used for the purpose of study. Though similar meteorological parameter profiles are employed, the conclusive results arrived at vary as the study is carried out during different periods of time.
