Below normal monsoon in last 30 days in Southern peninsula

The dry phase from a passing Madden-Julian Oscillation (MJO) has ended. In the wet phase we can see how it helps the interior parts of the southern peninsula and also North East India. As on 27th June the mighty Cherrapunji (Annual 12000 mm) has got only 1101 mm which is below normal by 1396 mm. The same can be said for Passighat (Annual 4300 mm) which has got only 292 which is below normal by 463 mm. Shirali (Annual 4100 mm)in Karnataka has got only 934 mm which is below normal by 285 mm. Coochbehar (Annual 3400 mm) in West Bengal has got 376 mm which is below normal by 271 mm. Same way Buxa, Maheran have also got below normal rains.


In Tamilnadu except Chennai all district are having deficient rainfall.

The same is throughout Southern India. I have done a analysis and you can yourself see the results for the rainfall in last 30 days

Chennai receives 72mm rainfall in 1 hour

Rain takes Chennai by surprise. Receives 72mm in less than a hour

— Photo: K. Pichumani.

SURREALISTIC LOOK: A slice of the rain-soaked city on Monday.

Heavy rain that lasted over an hour caught people unawares in many parts of the city and suburbs on Monday evening.

The Meteorological Department in Nungambakkam registered 70.2 mm of rainfall during the 12-hour period ending 8.30 p.m. This is much mor e than the monthly average of 53.7 mm. Meenambakkam recorded 46 mm of rainfall during the same period. The sharp showers came after a sultry day as Nungambakkam and Meenambakkam recorded a maximum temperature of 38.4 degree Celsius and 38.8 degree Celsius, one degree above the average temperature this month. Several localities in and around the city, including Aminjikarai, Anna Nagar, T.Nagar, Koyambedu and Pallikaranai, experienced heavy showers accompanied by loud thunder. Some interior roads, including Arunachala Naicken Street at Chintadripet, were flooded. Besides affecting the traffic on arterial roads, many bus services were also hit.

The scattered materials near the Metro Rail project site at Kathipara junction following rains aggravated the traffic snarl on the stretch. Traffic was thrown out of gear for a couple of hours around Guindy and Saidapet with vehicles piling up for prolonged period of time. Murky sky and heavy showers around 7 p.m. took motorists by surprise and many of them took shelter under trees and shops. V.S. Rajkumar, a resident of Nerkundram, said “I had to wait at a teashop for almost 20 minutes until the rain subsided.” Residents of southern suburbs such as Medavakkam, Perungudi, Sholinganallur and Velachery complained of power cut for almost an hour.

Officials of the Meteorological Department said heavy downpour within an hour was caused by thunderstorm activity. However, such rainfall in June was not unusual. Last year, 53.4 mm of rain was registered in 24 hour period on June 28.

The highest recorded rainfall in a single day was 347.9 mm on June 14, 1996. (Which was accompanied by Tropical Storm) The department forecasts that the rain or thundershower would occur in some areas of the city and the maximum temperature would be 39 degree Celsius.
