New Delhi:
Dense fog and numbing cold gripped Delhi on New Year's Day as the mercury plummeted to 1.1 degrees celsius, the lowest in 15 years. The minimum of 1.1 degrees celsius was recorded by the Safdarjung Observatory, which provides representative data for the city, the weather department said.
On January 8, 2006, the city had recorded a minimum of 0.2 degree celsius.
The lowest minimum temperature recorded in January last year was 2.4 degrees celsius, the India Meteorological Department (IMD) said.
Kuldeep Srivastava, the head of the IMD's regional forecasting centre, told NDTV that "very dense" fog lowered visibility to "zero" metres at Safdarjung and Palam at 6 am. Mr Srivastava said the minimum temperature will start rising from tomorrow under the influence of an "intense" western disturbance which will affect northwest India from January 2 to January 6. The minimum temperature is predicted to rise to 8 degrees Celsius by January 4-5.
"The minimum temperature of 1.1 degrees Celsius is the coldest in 15 years. In 2006, the temperature dipped to 0.2 degrees celsius. Cold wave conditions will persist today but the temperature will rise from tomorrow," Mr Srivastava said.

According to the IMD, "very dense" fog is when visibility is between 0 and 50 metres. In case of "dense" fog, visibility is between 51 and 200 metres, "moderate" 201 and 500 metres, and "shallow" 501 and 1,000 metres.

Delhi recorded a minimum of 3.3 degrees celsius on Thursday. At 15.2 degrees celsius, the city recorded the season's lowest maximum temperature on December 18.

Severe cold wave: A look at states with lowest temperatures in India
"During the next 2-3 days, the minimum temperatures are very likely to remain below normal over most parts of northwest India due to the prevalence of dry north and northwesterly winds," the IMD said.

Snow-clad western Himalayas have brought the minimum temperature down in most areas of north India, with the India Meteorological Department declaring severe cold wave in many parts. The IMD declares a cold wave in plain areas if the minimum temperature dips to 4 degrees Celsius. A severe cold wave is when the minimum is 2 degrees Celsius or less.

"During the next 2-3 days, the minimum temperatures are very likely to remain below normal over most parts of northwest India due to the prevalence of dry north and northwesterly winds," the IMD said.

Here is a list of places that are currently reeling under cold wave:
Delhi:
The minimum temperature in Delhi fell to 2 degrees Celsius on Thursday, which is five degrees below the normal for this time of the year, as the city reeled under a severe cold wave. Weather stations at Lodhi Road, Ridge and Safdarjung recorded a minimum of 2.4, 3.6 and 3.2 degrees Celsius respectively. A cloud cover that has been there over the city due to the influence of successive Western Disturbances has resulted in Delhi registering above-normal minimum temperatures since Monday, according to news agency PTI.

Jammu and Kashmir: Srinagar also recorded a low of minus 8.4 degrees Celsius, which was the coldest temperature recorded in the city in 30 years, according to IMD. Several water bodies in Kashmir, including Dal Lake, froze as the rally reeled under intense cold. Pahalgam tourist resort recorded a low of minus 11.1 degrees Celsius and was the coldest recorded place in Jammu and Kashmir.
Himachal Pradesh: Himachal Pradesh's Keylong and Kalpa also shivered at minus 11.4 degrees Celsius and minus 2.6 degrees Celsius respectively, while the state capital Shimla registered a low of 5.7 degrees Celsius.
Rajasthan: Ganganagar in Rajasthan was recorded as the coldest place at 0.2 degree Celsius. Sikar, Bhilwara, Churu, Pilani, Chittorgarh and Ajmer recorded their respective lows of 1.5, 1.8, 2.2, 2.9, 3.5 and 4.8 degrees Celsius respectively, while the day temperature at other places was between 5 and 9 degrees Celsius, IMD said.

Haryana: Haryana's Narnaul recorded a temperature of 1.8 degrees Celsius, three degrees below normal, on Thursday. Ambala, Hisar and Karnal too experienced cold wave at 3.1, 3.7 and 4 degrees Celsius respectively.

A thick blanket of fog reduced visibility to zero metres in the national capital on Saturday, affecting traffic movement, the India Meteorological Department said.



This is the third time this season, after December 8 and January 1, that visibility has dropped to zero metres in the city.
'Very dense' fog lowered visibility to zero meters at Palam and Safdarjung. 'Dense' fog is predicted in parts of the city on Sunday as well, an IMD official said.
https://www.rediff.com/news/report/pix-dense-fog-shrouds-delhi-rail-air-traffic-affected/20191230.htm
According to the IMD, 'very dense' fog is when visibility is between 0 and 50 metres. In case of 'dense' fog, visibility is between 51 and 200 metres, 'moderate' is between 201 and 500 metres, and 'shallow' is between 501 and 1,000 metres.
Delhi recorded a minimum temperature of 6.6 degrees Celsius, a notch below normal, on Saturday. The Lodhi Road weather station recorded a minimum temperature of 5.8 degrees Celsius.
On Friday, the Safdarjung Observatory, which provides representative data for the city, had recorded a low of 6.4 degrees Celsius. It was 2 degrees Celsius on Thursday and 3.2 degrees Celsius on Wednesday.
There was no improvement in the city's air quality which remained in the 'severe' category on Saturday.
The air quality index had entered the 'severe' category on Thursday due to "extremely unfavourable" conditions for the dispersion of pollutants, government agencies said.
The city's AQI was 436 at 9 am. The 24-hour average AQI was 460 on Friday, 429 on Thursday, 354 on Wednesday, 293 on Tuesday and 243 on Monday.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.



Kuldeep Srivastava, the head of the IMD's regional forecasting centre, said the wind speed has slowed down and the moisture in the air has made the pollutants heavier.
The central government's Air Quality Early Warning System for Delhi said slow winds and ventilation conditions are "extremely unfavourable" for the dispersion of pollutants.
This will lead to further deterioration of the air quality, the agency said.

Owing to the low visibility, 10 trains were delayed in the morning after the minimum temperature settled at 7 degree Celsius.
Moreover, flights into and out of Delhi were delayed and diverted from 5:30 am to 7 am after the fog reduced visibility to 50 metres.
https://www.rediff.com/news/column/the-great-gloom-of-delhi/20181115.htm
The official data maintained by the Centre-run System of Air Quality and Weather Forecasting And Research put the condition at severely polluted. The Particulate Matter 2.5 level was recorded at 146 while the PM 10 was at 233 in New Delhi.



At Dhirpur, the AQI was 420 at 8 am, while in Mathura Road area, it dipped to ‘hazardous’ category with AQI 423. AQI near Pitampura, Airport Terminal 3 and DelhiUniversity stood at 434, 397 and 448, respectively.

An AQI between 0-50 is considered good, 51-100 is satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor and 401-500 is marked as severe/hazardous.
People residing in Delhi have been advised to avoid all physical activity outdoors and move activities indoors.
“Sensitive groups must stop outdoor activity at early morning and after sunset times. Avoid prolonged or heavy exertion. Go for a short walk instead of a jog and take more breaks. Stop any activity level if you experience any unusual coughing, chest discomfort, wheezing, breathing difficulty, or fatigue. If the room has windows, close them. If the air conditioner provides a fresh air intake option, keep that closed,” stated an advisory published by SAFAR.

According to the latest report published by the World Health Organisation, as many as one million lives in the world can be saved if all countries reduce the menace of air pollution in accordance with the Paris Agreement by 2050. WHO presented this report at the United Nations Climate Change Conference (COP24) in Katowice last month.



“The Paris Agreement is potentially the strongest health agreement of this century,” said Tedros Adhanom Ghebreyesus, Director-General of WHO. “The evidence is clear that climate change is already having a serious impact on human lives and health. It threatens the basic elements we all need for good health-clean air, safe drinking water, nutritious food supply, and safe shelter-and will undermine decades of progress in global health. We can’t afford to delay action any further,” the report read.

Unusually wet, warm January for South India: IMD
January 2021 was India's warmest since 1958

By: Express News Service | Pune | February 10, 2021 6:24:29 pm


India temperature, India weather


For the upcoming two weeks this month, the Met department has forecast rainfall activity over central India, including Jharkhand and Odisha, during February 16-19, whereas it will remain dry over remaining regions during remaining days this month. (File photo)
This January has been the warmest-ever recorded over the South Peninsular India in 121 years with the average monthly minimum temperature reaching 22.33 degrees.
Meanwhile, South India recorded a prolonged wet spell for 17 days, resulting in a significantly wet month. Such rainfall added to the overall monthly rainfall in the country, which was in excess by 17 per cent with respect to the Long Period Average (LPA), the India Meteorological Department (IMD) stated in its latest monthly weather report.
Heavy and frequent rainfall events, lasting 8 to 10 days, kept the temperatures along South India above normal for most days. For three consecutive weeks, between December 31 and January 20, surplus rainfall — 807 per cent, 1036 per cent and 727 per cent — were reported mainly over Tamil Nadu, Karaikal and Puducherry.


The country also experienced the warmest January in 62 years. Recurrent western disturbances resulted in frequent precipitation on extreme north and northwest India during the beginning of the month.

Along with 1958, January’s average monthly minimum temperature recorded this year was 14.78 degrees. This even as January 1919 (15 degrees) remains the warmest ever that the country has ever recorded. Central India, too, recorded a warmer than usual January since 1982, as the average monthly minimum temperature last month was 14.8 degrees.
For the upcoming two weeks this month, the Met department has forecast rainfall activity over central India, including Jharkhand and Odisha, during February 16-19, whereas it will remain dry over remaining regions during remaining days this month.
Even though winter is nearing its draw for the season, the Met department has warned that foggy conditions will prevail over Delhi, Punjab, Haryana, Chandigarh and west Uttar Pradesh all through the remaining days of February.

SKYMET WEATHER FORECASTS MONSOON PROBABILITIES FOR INDIA IN 2021, LOOKS NORMAL SO FAR
January 31, 2021 9:30 AM | Skymet Weather Team


Monsoon 2021 forecast


“There is sufficient cooling in the Pacific Ocean now and La Niña conditions are at the peak. The Sea Surface Temperatures (SSTs) are likely to rise soon and the probability of continued La Niña will fall. This will reduce to about 50% when the Monsoon arrives. This could be one of the ‘normal’ Monsoon years making a sound start and ending within the upper half of normal range, range of normal rainfall is 96-104% of LPA (880.6mm). Initial readings are indicative of some risk attached to few pockets.
Monsoon is the largest and most challenging seasonal weather phenomenon. There are precursors to get an early glimpse and gauge its health during the four-month-long season. Last year Monsoon was driven by La Niña which is peaking right now. It will decline during the ‘spring’ and turn neutral later through the Monsoon season. It also means that Monsoon 2021 is going to be a devolving La Niña to start with. This trend of Pacific Ocean temperatures may not lead to an above normal or excess rainfall, but chances of a disfigured Monsoon are also ruled out so far.


However, ENSO is wielding a spike which needs to be ascertained with the model forecast in February and March. This will get factored in our April forecast. IOD events are typically unable to form till April, but the early indications suggest it to be neutral at the commencement of Monsoon”. – Jatin Singh, Managing Director & Founder, Skymet Weather Services Private Limited.
Skymet has been predicting Monsoon since 2012 and is committed to release report on prospects of Monsoon 2021 soon. Due to strategic reasons and judicious deliberations, Skymet did not share its Monsoon report of 2020.
