Mercury shoots up in region

By Staff Reporter

GUWAHATI, April 30 � An approximately rainless condition for about a week now has caused the maximum temperature to shoot up above the normal all over the NE region, except in Shillong. However, during the next 48 hours, it is expected that a thunder squall may occur at one or two places over Assam and Meghalaya with the wind speed exceeding 50 kilometres per hour.

According to sources in the Regional Meteorology Centre (RMC) here, Shillong recorded a maximum temperature of 21.02 degree Celsius today, against 24 degree Celsius, which is its normal for the period.

Guwahati recorded a maximum temperature of 34.5 degree Celsius, against its normal of 32 degree Celsius and Dibrugarh recorded a maximum temperature of 34 degree Celsius, against its normal of 29 degree Celsius, said the RMC sources.

RMC Deputy Director General H Pathak told this newspaper that this year, till April 28, the State recorded a (-) 28 per cent rainfall, while during the corresponding period last year it recorded a (+) 85 per cent rainfall. But in the preceding year, the State recorded a rainfall of (-) 30 per cent.

This is due to the year-to-year variation in rainfall activities, Pathak said.

He maintained that in the State, rainfall during the pre-monsoon period occurs due to local thunderstorm activities. This year, such activities are comparatively less.

Whatever rainfall we are getting this year, is mostly associated with the trough of low extending from Bihar and its adjoining areas to North East Assam as well as the cyclonic circulation or the trough associated with wind system over the sub-Himalayan West Bengal and its adjoining areas.

During the last week, a cyclonic circulation was seen over the Gangetic West Bengal and adjoining areas in the Lower atmospheric level, which resulted in occurrence of rainfall at a few places over Nagaland, Mizoram and Tripura and isolated rain occurred over the rest of the region during the period, Pathak said.
