New Delhi: There will be no respite from
searing heatwave conditions for the next couple of months as a
strong anti-cyclonic system is sitting over central and
north-west India and showing little signs of moving away.
However, the weatherman has said the heatwave conditions
could augur well for the Monsoon as heating of central India
is one of the parameters that indicate a good rainy season.
"In the near future, we don`t see any major change to
take place. The hot conditions will continue. Both the day and
night temperature is going to stay on the higher side," Ajit
Tyagi, Director General of India Meteorological Department
(IMD), said in an interview.
A strong anti-cyclone system is active over central and
north-west India and only a stronger extra tropical weather
system or cyclonic activity in the Bay of Bengal could
dislodge it resulting in some relief from the heat, he said.
"Any major change can be caused only by a change in air
mass associated with active disturbance. That is not taking
place this season and it is continuing. It is likely to
continue also," Tyagi said.
An anti-cyclone is a large atmospheric circulation system
associated with relatively high pressure at the surface and in
the lower troposphere.
Anti-cyclones usually form when an airmass is cooled over
a cool ocean surface, or over land during winter when little
sunlight is available.
This heat spell may be a boon in disguise for the farmers
as absence of rain or hailstorm would enable them to have a
smooth harvest of the rabi crop and good rains would certainly
be of help for the kharif season.
"There is no hailstorm or rains in March or April so far.
The wheat crop is not affected. Many a time in March, a good
spell of rain and hailstorm affects the crops. Heating is
positively causing discomfort putting stress on water, power
but it is good for (weather) system," he said.
Asked about the reasons for the summer setting in early,
Tyagi said it was not unusual as the heat has started in
February in 2006 and this year it started by March. "The
reasons are clear. One is the prolonged clear skies because of
absence of clouds," he said.
April began on a `hot note` with temperature touching
higher levels. The maximum touched 43.7 degrees Celsius
yesterday, a 52-year high for the month of April.
On whether a hot April is an indication of much hotter
summer ahead, Tyagi said there is no denial of the fact that
it is going to be a hot summer. Temperatures in May will be on
a higher side, he added.
