A Theoretical Consideration For Sea Breeze Circulation In Peninsular India

V.LakshmanaRao , P.Satish

Sea breeze circulation very much dependent on only solenoidal term which accounts for differential heating between land and sea .The Coriolis force which always acts for perpendicular to the direction of motion is reflective force its changes the direction but not the magnitude. The Coriolis parameter is given by the expression 2Ω Sin�?�?, here Ω is the angular velocity of the earth (7.2×10-5/s), and �?�? in the above expression denotes latitude. The Coriolis force is zero at equator and maximum (2Ω) at poles. For the three typical stations on the East coast of India Coriolis parameter is 4.38×10-5 Visakhapatnam 3.324 ×10-5 Madras and 2.2 × 10-5 for Tuticorin .The penetration will be more as we move south toward equator. A similar estimation of f (2Ω sin�?�?) can be done for West coast the typical value for the stations Trivandrum 2.076×10- 5, Goa 3.799×10-5, and Bombay is 4.581×10-5. Theoretically speaking the peninsular India can be considering hypothetically as a triangle whose area reduce as one moves to the south .A situation arises at southern regions that two sea breeze fronts from west as well as East come in the opposite direction and both can be meeting on which case there will be more convection and this may be lead to thunderstorm activity are well known in the southern part of Tamilnadu and Kerala.
