GUWAHATI, June 9 - Rainless conditions for a long time, along with a clear sky, have led to the soaring of the day temperature and the hot weather-related discomfort of Guwahatians.
The impact of the ascending day temperature is being felt more in the downtown areas, where the green cover has been drastically replaced by paved surfaces, making them radiate the heat in an analogous manner to the solar emission.
Sources in the Borjhar-based Regional Meteorology Centre (RMC) told The Assam Tribune that Guwahati today recorded a day temperature (maximum temperature) of 38.3 degrees Celsius. Yesterday, the city recorded a day temperature of 36 degrees Celsius and on Thursday, the day temperature was 35.8 degree Celsius.
For Guwahati, the highest day temperature in the month of June was recorded on June 12, 2013 in the recent period. That day, the city recorded a day temperature of 38.8 degrees Celsius.
However, the city recorded the all-time high day temperature of 40.6 degrees Celsius on April 24, 2014, sources said.
RMC sources maintain that the downtown areas of Guwahati may record a slightly higher day temperature, varying between 1 degree Celsius and 1.5 degrees Celsius, compared to what it records at the Borjhar RMC office.
Stating that there was a likelihood of rain over the city on Saturday night, RMC sources maintained that South West (SW) Monsoon is yet to cover the entire Nor-theast. It has so far covered Mizoram, Manipur, Nagaland, Tripura, some parts of south Assam and northeastern parts of Arunachal Pradesh.
Advance of the SW Monsoon is being prevented by a new cyclonic circulation lying over the South China Sea. This system has been present over that area for the past two days. It was preceded by another cyclonic circulation over the same area about three to four days back.
On the other hand, the Indian Ocean Dipole (IOD) is still absent, and, because of this, sea wind of the area is moving towards the South China Sea. Besides, the upper air easterly wind, at a height of 10 km above sea level, is yet to be generated over the Pacific Ocean.
These reasons have been restricting the movement of moisture-laden wind towards the North East in the desired manner. Hence, the delay has occurred in the total onset of SW Monsoon over this region, sources said.
However, in the next 48 hours, the system over the South China Sea is expected to move away in a northeastward direction and subsequently moisture-laden wind will start flowing to the Northeast, thus triggering rainfall activities over the entire region, sources said.
