WHAT ABOUT THE PRE-Monsoonal Activity???
After looking at the forecast for cyclone in may, many will ask me about the premonsoonal activity.
The premonsoonal activity likely to take a sharp turn from April 23rd and fetch some good showers to Kerala, Interior Tamilnadu, Parts of South-interior Karnataka. As the Line of Wind discontinuity (LWD) moves inland of south india, rainfall will occur during evening times with loud thunder and even hail at some places.
This time the Premonsoonal rainfall seems less over south-eastern india and adjoining areas of andhra pradesh, Telangana.
Moist winds from Arabian sea enter the inland viz. Kerala, Coastal karnataka and finally enter the interior parts of south india. The sun heats up the inland and causes the upward motion of air molecules, which is referred as instability of the atmosphere. The cloud popups will be forming and cause some rain spell, depending on wind-shear, adiabatic lapse rate, Moisture, Convergence at lower levels, Cape and wind-flow.
I am expecting a Start of thunderstorm season, when the wind-flow over kerala persist moisture. I see some similar conditions from 22nd april. Adding a day, tamilnadu will get some rains from 23rd april. Meanwhile heat will persist over andhra and telangana with some intermediate showers.
