Short summary
Short summary
Study of the diurnal variation of the atmospheric boundary layer (ABL) height is important for the knowledge of pollutant dispersion, crucial for all living beings. The most difficult part in the study of the diurnal variation is in identification of the stable boundary layer which occurs ~ 50% of times only and mostly during nighttime winter. Surface temperature and clouds directly affect the diurnal pattern of the ABL. Thus, stronger (weaker) diurnal variation found during pre-monsoon (winter).

Short summary
Monsoon inversion (MI) over the Arabian Sea is one of the important characteristics associated with the monsoon activity over Indian region. The initiation and dissipation times of MI, their percentage of occurrence, strength etc., has been examined. We suggest MI could also be included as one of the semi-permanent features of southwest monsoon.
Short summary
The evolution of the convective boundary layer (CBL) directly affects the day-to-day activity of living things by controlling the transport of pollutants, anthropogenic emissions, and moisture. During summer monsoon season cloudiness prevails over the Indian region. We found that the CBL is shallower during cloudy days compared to clear-sky days, whereas cloud at the CBL elevates its height. Thus, occurrence of cloud plays an important role in the day-to-day variation in the CBL height.
