|Cold weather condition likely to continue in NE|
GUWAHATI, Jan 2 - The present cold weather condition is expected to continue over the North East (NE) region of the country during the first week of the New Year. People of the country’s north-eastern region had to bid farewell to the year 2019 and welcome the New Year 2020 with a shiver. Sources in the Regional Meteorology Centre (RMC) here attribute this to the presence of a Western Disturbance system, together with other allied factors.
The Western Disturbance system as an upper air trough extending between East Arunachal Pradesh and Manipur, together with a strong northerly wind at a height of 5.8 km above the mean sea level (ASL), produced light snowfall activities over parts of Kiphire, Zunheboto and Tuenchang districts of Nagaland on December 30, 2019. The northerly wind brought in cold air from the Upper Tropospheric region to create a favourable condition for that development.
Though the India Meteorology Department does not have any record of snowfall over Nagaland in the past years, locals claim that they have witnessed snow fall in these areas after a break of about 40 years.
RMC sources here maintain that hail storms are expected at the higher reaches over Khasi-Jayantia Hills of Meghalaya today. Tomorrow, heavy rainfall activities are expected at isolated places over Southern Mizoram, while light to moderate rainfall activities are expected at most places over Nagaland-Manipur-Mizoram-Tripura and at many places over Assam-Meghalaya and Arunachal Pradesh meteorological subdivisions.
These rainfall activities are expected because of the presence of a Western Disturbance system as an upper air trough, which is running roughly along 90 degree east, north of 24 degree North, at a height of 3.6 km ASL, sources said.
It is expected that the cold weather-related situation in the NE region will start improving from January 5, 2020 or from the morning of January 6, 2020. But over the entire region, a gradual fall in night temperature is expected from January 6, 2020, which will make the nights colder for a couple of days, sources in the RMC said.
