Shillong: The long spell of cold weather that hit the state in general and Shillong in particular in January was mainly due to the maximum temperature falling below the average recorded for the month over the years.
Rakesh Kumar, Scientist at the Indian Meteorological Department (IMD), here said, “In January maximum temperature went down to 11.7 degree Celsius to 12.2 degree Celsius while the average for the month is 14.9 degree Celsius.”
Kumar said that the day time lowest temperature was around 13 degree Celsius in January 2021.
“January 6 onwards, continuous cloudy days and back-to-back western disturbances have caused the cold weather, ” he said.
Kumar added that going by the temperature alone, there is not much variation but because of less sunshine during the day temperatures are lower and, therefore, the feeling of cold is more.
He added that generally cloudy days were less in previous years with the days being sunny. “The temperature is low during the night, but one will not feel it because most of the people are inside their homes.
The IMD official also said that this is happening because of the frequent western disturbances.
“One western disturbance will impact the state from Friday. Two days of moderate rainfall with possibility of hail is there,” Kumar added.
He also said that the all-time low for coldest temperature is -0.9 degree Celsius recorded on January 30, 1971 while average rainfall for the month is 8-10 mm.
“But this year we got 16 mm of rain. It can happen in one day itself,” Kumar said.
The IMD official also informed that the temperature in February will remain lower than normal.
According to Kumar, from 1981 to 2010 the average minimum temperature was 7.5 degree Celsius while the maximum was 17 degree Celsius.
