On behalf of all the weather bloggers at COMK we wish our readers a Happy Independence Day. Southwest Monsoon season this year has been fairly eventful for core Monsoon Zone in Central India. Overall in terms of dynamics it is fair to say Monsoon Intra-seasonal Oscillation (MISO) has skewed towards Central India. The weekly progression…
Strengthening westerlies to reduce thunderstorms over leeward TN
As we often mention monsoon dynamics is an oscillating pendulum. Very rarely one can see it an equilibrium state. Depending on atmospheric support the movement of pendulum may be fast or slow. When monsoon winds weaken from the west along with break in monsoon thunderstorms improve over leeward plains of TN. When strengthening westerly winds…
Window of thunderstorms for North Coastal TN
Over the past few days as Southwest Monsoon slowed a window of thunderstorms opened for the leeward plains of TN. Widespread thunderstorms pushed the seasonal rainfall performance for TN & PDC from -11% to 3%. The last 5 days have contributed nearly 30 mm to the seasonal rainfall tally over TN & PDC. But in…
Shear Zone over South Bay to bring back thunderstorms for TN
The moody Southwest Monsoon continues to swing back and forth with alternating active and weak phases for Peninsular India. These constant mood swings has also meant the 1st half of monsoon has not seen a classic break period. The first classic break in monsoon period is almost upon us looking at how things are shaping…
Break in Monsoon coming up for SWM 2025
Like pretty much every atmospheric phenomenon Monsoon is also an oscillating event. Intra seasonal oscillation is an essential component of Southwest Monsoon. Even as early as 1950s and 1960s researchers started to look at Break in Monsoon phenomenon. People like Dr. C Ramaswamy, P Koteeswaram, both of whom went onto become Director General IMD, studied…
