New Delhi:
In May, the maximum temperature Delhi recorded was on May 10
at 40.9 degrees Celsius, two degrees above normal.
Most parts of the country will experience the indirect
impact of Super Cyclone Amphan, which weakened into a deep depression on
Thursday and sent the maximum summer temperatures soaring.
India Meteorological Department (IMD) on Thursday said there
will be a two-four degrees Celsius rise in maximum temperature over northwest,
central and west India in the next to three days.
IMD has warned of a heatwave over Rajasthan between Thursday
and Monday; western Madhya Pradesh (MP), Vidarbha, and Telangana from Thursday
and Sunday; over coastal Andhra Pradesh, north interior Karnataka, and Tamil
Nadu, Puducherry, and Karaikal from Thursday to Saturday, over east Madhya
Pradesh and Rayalseema and over Uttar Pradesh (UP) from Friday to Sunday.
A feeble Western Disturbance is expected to impact Western
Himalayas on Friday, which is likely to bring rain and thundershowers to Jammu
and Kashmir; Himachal Pradesh and Uttarakhand and light thundershowers to
Haryana, Punjab, and Delhi but maximum temperatures are likely to rise even in
the northern plains, IMD scientists said.
In May, the maximum temperature Delhi recorded was on May 10
at 40.9 degrees Celsius, two degrees above normal.
According to Skymet Weather, “heatwave conditions are likely
over Delhi and Haryana also after two to three days.”
“There are two
important factors — one is there is no clouding. There are clear skies almost
all over the country except where the cyclone or depression is. The other
reason is there is advection, wind patterns have changed after the cyclone.
Hot, dry north-westerly winds are blowing even over peninsular India, which
makes conditions favourable for heatwaves. Eastern MP, Rajasthan, UP, parts of
peninsular India are all likely to develop heatwave like conditions now. There
is no major weather system that can cause clouding. The impact of western
disturbances will also gradually reduce now leading to higher temperatures in
northwest India including Delhi,” said K Sathi Devi, head, National Weather
Forecasting Centre.
The highest temperatures recorded on May 20 were in Barmer
in west Rajasthan and Akola in Vidarbha at 44.2 degrees Celsius. There are two
criteria for the recording of heatwaves—when the maximum temperature is at
least 40 degrees Celsius and departure from normal is 4.5 degrees Celsius to
6.4 degrees Celsius. A heatwave is also declared when the maximum temperature
is over 45 degrees Celsius for two stations in a sub-division for two days.
“Because of cyclone
Amphan, all the moisture is concentrated around it while dry, north-westerly
winds are blowing over the rest of the country which causes temperatures to
peak gradually,” said Sunita Devi, who is in-charge of cyclones at IMD.
Not just the rest of May but even June could be very hot in
many parts of the country. “If there is no western disturbance, north-west
India will be hot even in June. Hot winds from desert regions will heat up the
region as wind patterns have changed after Amphan,” said DS Pai, senior
scientist at IMD Pune.
