The year 2016 was marked by anomalies in weather patterns, with high heat and less-than-normal rains during the monsoon caused by a fewer number of depressions in the Bay of Bengal and also a full winter arriving later than scheduled as the year bid adieu.
Meteorologists at the Bangladesh Meteorological Department (BMD) noted the anomalies in their annua; review, but were yet to attribute these to climate change or global warming. “We have noted something in it that requires further studies before we can reach a conclusion,” said a meteorologist.
April was the cruellest month in Bangladesh, during which the mercury climbed to 40.6 degrees Celsius in Jessore.
The hear wave ran for 21 days, from the south-western Khulna division up to the north-western Rajshahi division, making life unbearable.
After the sizzling heat, the rains finally came with lightning strikes, killing at least 33 in different parts of the country, said Abul Kalam Mallick, a meteorologist at the Dhaka Met Office, who has been studying the pattern of abnormalities in the weather.
The spurt in heat was somewhat intriguing, climbing vertically from a moderate heat wave in March with 30–34 degrees C to 36 degrees C and then to 40.6 degrees C.
After that, three cyclones visited the coastal areas, brewing off a few low-pressure systems from the Bay of Bengal. Two of those were named ‘Kyant’ (meaning a crocodile crawling out of the sea in Burmese) and ‘Verdah’ (meaning blossoming like a rose petal, a name given by Pakistan). However, Cyclones Kyant and Verdah faded away without causing much damage. In between, another cyclone—Roana—menaced the Bangladesh coast. It, too, did not cause much damage, except for whipping up the sea in May.
Again, Cyclone Nada came roaring from the Bay in end-November eventually to pass towards India.
Two depressions during the monsoon in August caused heavy rains across the country. But rains in July were less, when the monsoon showers reach their peak. June rains, though, were more than average, causing floods in Assam and Bangladesh, and saw the deluge sweeping an elephant from among a wild herd roaming reserve forests in Assam. It died in Jamalpur on June 27, after defying attempts by foresters and veterinarians from the forest departments of Assam and Bangladesh, to put the beast to sleep, using tranquiliser darts, and rescue it.
Floods followed later in July and August, and were serious.
Overall, the rains during the monsoon were around 71 per cent, said Abdul Kalam Mallick. He attributed it to the few low pressure zones, depressions and deep depressions churning out four cyclones.
After the monsoon ended, the cold season did not materialise, defying the forecasts till the closing days of the year.
