GUWAHATI, Oct 31 - Even as the appearance of dew droplets, together with fog or mist covers, has been reported from some of its places, the NE region may have to wait for at least a week this year to greet the pleasant autumn days. Thursday was the last day of October. Usually, autumn arrives in this part of the globe with the beginning of the month of October every year.
But this year the temperate Northerly and Northwesterly winds which bring down the soaring summer temperature and thus pave the way for a moderate weather condition, have failed to reach the NE region because of the obstacles created by the cyclone Kayarr over the Arabian Sea for the past several days, sources at the Borjhar-based Regional Meteorology Centre (RMC) said.
Though Kayarr is now moving towards Oman, another cyclone Maha developing over Lakshadweep in the East Central Arabian Sea, has now been preventing the flow of the Northerly and Northwesterly winds to the NE region.
These two cyclones are also getting support from the absence of a high pressure system over Central India and a cyclonic circulation that is prevailing over Bangladesh and its neighbourhood, up to a distance of 2.1 km above the mean sea level, in preventing the flow of the Northerly and Northwesterly winds to the NE region.
The developments are such that another low pressure area is likely to emerge over the North Andaman Sea on November 3 and it is very likely to move west-northwestward and concentrate into a depression over the Bay of Bengal during the subsequent 48 hours from November 3.
All these meteorological developments are likely to keep the atmosphere warm in the NE region, by obstructing the flow of Northerly and Northwesterly winds to the region. Hence, it is anticipated that a warm weather condition is likely to prevail over the NE during the first week of November this year, sources said.
Meanwhile, the appearance of dew droplets has been reported from parts of Guwahati, Dibrugarh, Imphal, Silchar, North Lakhimpur, Barapani, Agartala, Lengpui and other places of the region during the past 24 hours. Fog or mist covers have also been reported from Silchar, Barapani, Kailasahar, Agartala etc., during the period, sources said.
