Climatological characteristics of sea breeze parameters at Chennai
Keywords:Chennai, Chennai AP, Sea breeze, Onset, Withdrawal, Duration, Coriolis force, Superposed epoch analysis, Anti sea breeze, Mixing depth
Several sea breeze parameters such as time of onset, withdrawal, duration, depth, variation with height, direction etc. have been derived and studied for Chennai city and Chennai AP observatories in this study, which has been based on a large data base for the period March-October,1969-83. The monthly and sub monthly values of several sea breeze parameters have been derived. By invoking the concept of superposed epoch analysis the important role played by sea breeze in modulating diurnal variation of surface temperature and relative humidity has been established. The sea breeze at Chennai has been shown to be shallow with a depth of under 1 km. Modal directions of sea breeze and its normal speed have been derived.
