THIRUVANANTHAPURAM: After days of scorching heat, the state has hit a cool patch caused by excess summer showers. By the end of April, the state received 61 per cent excess summer rainfall. This is the second highest rainfall in the past five years. From March 1 to April 30, the state got 225 mm rainfall against the normal 140 mm. It was the low pressure formations in the Bay of Bengal which triggered widespread rainfall in the state in the last week. Surprisingly, the summer shower in the state was deficient till weeks ago.
Unlike the normal thundershowers during summer, the state received widespread heavy to very heavy rainfall, mainly owing to the presence of trough of low pressure and low pressure systems in the Bay of Bengal. Except Kannur, all other districts received excess rainfall. Kannur got 43 per cent deficient rainfall. Against the normal 65 mm, Kannur received only 37 mm rainfall. Ernakulam district received the highest rainfall. It got 211 per cent excess rainfall.
Against the normal 143 mm, Ernakulam recorded 445 mm rainfall. Kottayam is in the second position with 96 per cent excess rainfall. It received 349 mm against 178 mm normal rainfall.
The state recorded good summer showers back in 2008. Between the period of March 1 and April 30 in 2008, the state recorded 281 mm rainfall against 140 mm. This is the highest amount in the past five years.
‘’Summer rainfall was excess this year. However, this is not an unusual phenomenon. Sea surface temperature was higher this season. This was favourable for rainfall. Trough of low pressure and low pressure systems developed in Bay of Bengal and Arabian Sea activated good rainfall in the state,’’ K Santhosh, director, India Meteorological Department, Thiruvananthapuram, said.
Santhosh said low pressure formations are expected in May too. ‘’Also a trough extending from Telangana to Kerala will provide thundershowers in the coming days,’’ he added.
The northern Kerala was receiving poor rainfall till mid-April.
However, the heavy rainfall triggered by the low pressure in the Bay of Bengal changed the entire scenario.
