Heavy rains lash North East

By Staff Reporter

GUWAHATI, Aug 20 � With the monsoon trough coming back to its normal position and passing across it, rainfall activities over the NE region of the country have resumed, said Regional Meteorology Centre (RMC) sources here.

On the other hand, Agriculture Department sources here said that the worry of the farmers concerning the rainless condition is over with the State receiving rains once again.

Deputy Director General Meteorology (DDGM) of the RMC Haragovinda Pathak told this news paper that during the past 24 hours, since 8-30 am yesterday, Borjhar Airport recorded 102.10 mm of rainfall, while Cherrapunji recorded 182.2 mm of rainfall during the period.

Neamatighat recorded 69.8 mm of rainfall, Sivasagar recorded 66.0 mm of rainfall, Khanaapara in the city recorded 103.3 mm of rainfall and Dhekiajuli recorded 150.1 mm of rainfall during the period, Pathak said.

Most places over Assam-Meghalaya, Nagaland-Manipur-Mizoram and Tripura (NMMT) and many places over Arunachal Pradesh are expected to receive rainfall during the next 24 hours. Heavy to very heavy rainfall is likely to occur at a few places over Assam-Meghalaya and at one or two places over the rest of the region during the next 48 hours, said Pathak.

It needs mention here that the normal position of the monsoon trough in India is between Ganganagar in Rajasthan and Sagar Island on the Head of the Bay of Bengal, via Allahabad in Uttar Pradesh. But during the past several weeks, it shifted southward from its normal position and passed through Madhya Pradesh and Chattisgarh. This resulted in more rainfall activities over the mainland of the country during that time.

The rainfall activities in the NE region get reduced during this period due to this development. The location of the monsoon trough and the weather systems �� that is, low pressure area or depression,�- formed over the Bay of Bengal and Arabian Sea and their subsequent movements towards the Indian territories determine rainfall activities in India.

The NE region gets monsoon rainfall when such weather systems move or pass across this region.

This monsoon, between June 1 and August 20, Arunachal Pradesh has recorded 31 per cent deficit rainfall, while the amount of rainfall received by Assam during this period is ten per cent less than its normal in this respect. Rainfall measuring plus/ minus 19 per cent around the normal is considered to be normal in meteorology, Pathak said.

During this monsoon, Manipur recorded 52 per cent deficit rainfall, while Meghalaya recorded 54 per cent deficit rainfall during this period. Mizoram recorded a deficit of 11 per cent, Nagaland recorded a deficit of 24 per cent and Tripura recorded a deficit of 20 per cent in this respect.

The three districts of Barpeta (58 per cent), Chirang (27 per cent) and Sonitpur (37 per cent) of the State recorded excess rainfall during this monsoon.

On the other hand, Hailakandi (57 per cent), NC Hills (55 per cent), Karbi Anglong and Nagaon (35 per cent), Dhubri (29 per cent), Odalguri (27 per cent) and Karimganj and Goalpara (25 per cent) recorded deficit rainfall during this monsoon, Pathak said.
