At 3.6 degrees, Delhi feels like 2 ° due to strong, cold winds


Residents of northwestern India shuddered from cold snap or severe cold snap conditions on Tuesday, and icy winds blowing through the capital made the weather appear colder than it actually was. The Safdarjung Observatory, which provides representative meteorological data for Delhi, recorded a minimum temperature of 3.6 degrees Celsius.

Delhi’s “feel-like” temperature, which takes into account wind speed and humidity to assess how the human body perceives temperature, was as low as 2 degrees Celsius, meteorological scientists said. That was mainly due to strong cold winds blowing at 15-20km / h that improved perception of cold, they said.

“For example, in winter, a strong wind can feel much colder than the measured temperature would indicate. In contrast, on a humid summer day, it can feel uncomfortably hotter than air temperatures would suggest … ”according to the UK Met Office.

A cold snap occurs on the plains when the minimum temperature is 10 degrees Celsius or lower and / or is 4.5 notches lower than normal for the season for two consecutive days. A cold wave is also declared when the minimum temperature is below 4 degrees Celsius on the plain.

Lodhi Road and Ayanagar in Delhi recorded minimum temperatures of 2.7 and 2.6 degrees Celsius, respectively. The maximum temperature in the city on Tuesday was 18.1 degrees Celsius, 2 degrees below normal.

Many stations in the northern plains recorded minimum temperatures of 0 degrees or close to 0 degrees Celsius. Hisar and Narnaul, both in Haryana, recorded 0 degrees and 0.3 degrees Celsius, respectively. Amritsar (Punjab) registered a minimum temperature of 0.4 degrees Celsius. Bhilwara, Pilani, Sikar and Churu (all in Rajasthan) recorded a minimum temperature of 0.9, 0.9; 0.5 and 0.4 degrees Celsius, respectively.

“Severe cold waves were recorded in many parts of Punjab and Haryana and cold wave conditions were recorded in Delhi,” said Kuldeep Shrivastava, head of the Regional Weather Forecast Center.

“Extremely cold winds from Jammu and Kashmir and Himachal Pradesh, covered in snow, are now reaching the plains. The average wind speed was around 15 km / h in Delhi, which increased the feeling of cold, so that the “feeling” of temperature was around 2 degrees Celsius. Minimum temperatures will be low for the next two days and may even drop further, ”he said.

New Years Day is likely to bring relief, when the low temperature is forecast to rise to around 5 degrees Celsius and around 7 degrees Celsius on January 2-3, Shrivastava said.

A new western disturbance is likely to hit the western Himalayan region around January 4, which may bring light rain and downpours to the plains, including Delhi.

Influenced by strengthening cold and dry northwest / north winds at lower levels, minimum temperatures are likely to drop by around 2 degrees Celsius over most of northwest and central India over the next three days and increase by 3-5 degrees Celsius over the next three days (January 1-3).

Frosty conditions are likely in northern Rajasthan, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh, and Delhi for the next two days.

“Many parts of Northwest India are reaching freezing point. We expect December 31 to be the coldest. Around January 2, a cyclonic circulation is likely to form in southern Rajasthan and an anticyclone in Chhattisgarh and Odisha. A confluence zone is likely to develop over Madhya Pradesh and eastern Rajasthan that will likely bring rain to Punjab, Haryana and Delhi, ”said Mahesh Palawat, vice president of climate change and meteorology at the private forecaster Skymet Weather.

Highest Weather Station in India:

• India MD established a meteorological center in Leh in Ladakh on Tuesday. At 3,500 meters, it is the highest meteorological center in India.

• Being located in a strategically important western Himalayan region bordering China, Pakistan, Tibet and Afghanistan, IMD will report daily weather parameters for the region.

• Ladakh has a complex mountainous terrain with little annual rainfall of only 10 cm / year, making it a cold desert.

• You often experience extreme weather events such as cloudbursts, flash floods, glacial lake outbursts (GLOFs), avalanches, and droughts.

• Some examples include heavy rain in August 2010 and 2015, an avalanche at the Khardongla Pass in January 2019, and the frequent blocking of the Leh-Manali and Leh-Srinagar roads due to heavy snowfall on the mountain passes.

• The Leh Meteorological Center will strengthen the climate-related early warning system in Ladakh.

• To start with, IMD has established a surface observatory in Leh to report daily weather parameters such as humidity, temperature, and snowfall.

• Ladakh has four automatic weather stations, two each in both districts, of which one is in Drass, the coldest place in India. Real-time weather data is available online at the Indian Meteorological Department website.

• To improve the network, IMD proposes to install more weather stations next year in places like Nubra, Zanskar, Changthang and Parkachik, covering all of Ladakh.
