It's official. The deep depression has intensified into a cyclonic storm - Nivar - over southwest Bay of Bengal.
The Tamil Nadu government has rolled out many precautionary measures which included suspension of bus services in 7 districts - Pudukottai, Nagapattinam, Thanjavur, Thiruvarur, Cuddalore, Villupuram and Chengalpattu from 1 p.m., on Tuesday until further orders. The government has appealed to the people in these districts not to go out on November 24 and 25 as there are chances of fall of trees. The people should act as per the weather instructions given by the authorities through battery-operated radios.
If it takes the predicted path, Nivar will hit Delta districts hard. The IMD has sounded red alert in Ariyalur, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam, Cuddalore, Villupuram, Tiruvannamalai, Kallakurichi and Perambalur.

CHENNAI:
The Indian Meteorological Department (IMD) on Tuesday said the cyclonic storm Nivar would intensify into a very severe cyclonic storm with sustained wind speeds of 120-130 kmph gusting to 145 kmph.
S Balachandran, deputy director general of meteorology of Regional Meteorology Centre, said Nivar, now a cyclonic storm over southwest Bay of Bengal, moved westwards with a speed of 5 kmph during the past six hours and lay centred about 380 km east-southeast of Pondicherry and 430 km south-southeast of Chennai.

"It is very likely to intensify further into a severe cyclonic storm during the next 12 hours and into a very severe cyclonic storm during subsequent 12 hours. It is very likely to move west-northwestwards for the next 12 hours and then northwestwards. It is very likely to cross Tamil Nadu and Pondicherry coasts between Karaikal and Mahabalipuram around Pondicherry during November 25 late evening as a very severe cyclonic storm with a wind speed of 120-130 kmph gusting to 145 kmph," he said.
The Tamil Nadu CM Edapaddi K Palaniswami has declared a public holiday on Wednesday in view of the cyclone. EPS appealed to people not to venture out of their residences unnecessarily and to adhere to the guidelines issued by the government

Cyclone Nivar could hit hard and make landfall near Puducherry which, along with Tamil Nadu and Andhra Pradesh, is on high alert.
There has already been one death attributed to the cyclone. A 25-year-old, who was chopping a drumstick tree in Pudukottai as a precaution ahead of the arrival of the cyclone, lost his life when the branches fell on a power line.
The NDRF has earmarked 30 teams to launch rescue and relief operations.
Fearing the winds to be worse than Vardah in 2016, the IMD had already a sounded red alert in Ariyalur, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam, Cuddalore, Villupuram, Tiruvannamalai, Kallakurichi and Perambalur. While an orange alert is issued in north coastal districts like Chennai, Kancheepuram, Tiruvallur, Chengalpet and interior districts like Vellore, Dharmapuri, Tirupattur and Krishnagiri.

Many trains and flights have been cancelled.
Kalpakkam's Madras Atomic Power Station has activated its Cyclone protection Machinery too.

Delhi witnesses its coldest November in 71 years: IMD

Source: PTI - Edited By: Roshneesh Kmaneck

November 30, 2020 14:01 IST


The month of November was the coldest in the national capital in 71 years, with the mean minimum temperature dropping to 10.2 degree Celsius, according to the India Meteorological Department.


Delhi had recorded a mean minimum temperature of 10.2 degree Celsius in November 1949.


The mean minimum temperature for November was 9.6 degree Celsius in 1938; nine degree Celsius in 1931 and 8.9 degree Celsius in 1930, according to IMD data.

https://www.rediff.com/news/report/pix-welcome-to-chinas-kingdom-of-ice/20200115.htm
Normally, the mean minimum temperature for the month of November is 12.9 degree Celsius.
The mean minimum temperature was 15 degree Celsius last year, 13.4 degree Celsius in 2018 and 12.8 degree Celsius in 2017 and 2016.
Delhi also braved four cold waves in November -- on the 3rd, 20th, 23rd and 24th.
For the plains, the IMD declares a cold wave when the minimum temperature is 10 degree Celsius or below and is 4.5 notches less than normal for two consecutive days.
However, for small areas such as Delhi, a cold wave can be declared if the criteria is fulfilled even for a day, Kuldeep Srivastava, the head of the IMD's regional forecasting centre, said.
On Monday, Delhi recorded a minimum of 6.9 degree Celsius. This is the eight day this month that the minimum temperature remained below 10 degree Celsius.
On November 23, Delhi recorded a minimum of 6.3 degrees Celsius -- its lowest minimum temperature in the month since November 2003, when the city recorded a minimum of 6.1 degree Celsius, according to Srivastava.
The minimum temperature this month, barring on November 16, has remained 2-3 degree Celsius below normal in the absence of a cloud cover on most days, according to IMD officials.

Clouds trap some of the outgoing infrared radiation and radiate it back downward, warming the ground.
The month of October was the coldest in 58 years in the national capital.
The mean minimum temperature in October this year was 17.2 degree Celsius, the lowest since 1962, when it was 16.9 degree Celsius.

Colder winter in north, central India in December-January: IMD

Madhya Maharashtra, Konkan and the entire southern peninsular region will experience either a normal or a warmer winter this season, according to the weather bureau.

Rajasthan, New Delhi, Jammu and Kashmir and Ladakh, along with other states in Northern and North-western India, are set to experience a colder winter during December to January.
This was stated in the India Meteorological Department (IMD) seasonal forecast ‘Seasonal Outlook for Temperatures during December 2020 to February 2021’ issued on Sunday.

“During the winter season, below normal minimum temperatures are likely over most sub-divisions in the north, northwest, central and a few subdivisions in east India,” said the seasonal forecast.
Delhi recorded the decade’s coldest November day on Sunday, with the mercury settling at 7 degree Celsius, which was 3 degrees below normal.
During the next three months, west Rajasthan, east Rajasthan, Jammu and Kashmir and Ladakh, Chhattisgarh and east Madhya Pradesh subdivisions can expect below-normal minimum temperatures.

On the other hand, Madhya Maharashtra, Konkan and the entire southern peninsular region will experience either a normal or a warmer winter this season.

Explained
What’s behind the forecast

The IMD has attributed the forecast this year to ‘moderate’ La Niña conditions, the cold counterpart of El Niño -- both are opposite phases part of a natural ocean-atmosphere pattern in the tropical Pacific Ocean that are likely to switch every three to seven years, lasting for nearly 9 to 12 months with an irregular frequency and impacting weather across the globe. La Niña conditions have prevailed since August, with the wind blowing warm surface water and the cooler water rising to the surface. The IMD has said that La Niña conditions would continue till the end of the winter season, likely to bring a longer and colder winter in several parts of India.

Last two winters, particularly over the North and Northwest India, have remained severe.
In 2018, a phenomenon named polar vortex had brought highly cold winds from the North Pole penetrating lower latitudes, including India. Similarly, last year, a severe cold wave gripped Delhi and neighbouring areas for over three weeks in December.

This year, the cooler winter is linked to moderate La Nina conditions prevailing over the Pacific Ocean.

“During the La Nina years, minimum temperatures tend to remain slightly below normal. In addition, some synoptic conditions could help keep the temperatures below normal,” said Dr D Sivanand Pai, head, Climate Research and Services at IMD, Pune.
On the contrary, day time could remain warmer during these months over most areas, Pai added.
The seasonal forecast said that most subdivisions, except southern India, are likely to experience above normal maximum temperatures.
Weak conditions of La Nina –– the abnormal cooling of the seas along the central and equatorial Pacific Ocean –– prevailed since August. They have cooled further to become ‘moderate’ conditions recently. The IMD has said that La Nina conditions would continue till the end of the winter season.

Corals Can Still Bounce Back from Bleaching Even During Heatwaves if Humans Don't Interfere: Study

Coral reefs cover less than one percent of the ocean's surface but support a quarter of marine species, providing them with food and shelter.

Some corals can recover from bleaching even in long heatwaves as long as humans don't interfere, scientists said Tuesday, raising hopes for the endangered underwater ecosystems essential to much marine life.
Researchers tracked corals of the Kiritimati atoll in the Pacific Ocean through the longest tropical heatwave on record, expecting the reefs to suffer mass bleaching.


But despite sitting in a "hot water bath" for 10 months due to a particularly strong 2015/2016 El Nino, the studied corals survived.
"We were blown away... to find that not only were all the corals not dead! But some of them didn't even look to be in bad shape or bleached," said Julia Baum, co-author of the study published in Nature Communications.

"They had recovered while still under these stressful conditions!" the biology professor at Canadian Victoria University told AFP.
However, there is a catch. Only the corals undisturbed by human stress factors such as water pollution were more likely to survive the heatwave.

"We found that corals were only able to recover from bleaching while at elevated temperatures if they were not also exposed to other strong local stressors," Baum said.
Coral reefs cover less than one percent of the ocean floor but support a quarter of marine species, providing them with food and shelter.

Warming waters due to climate change cause corals to expel the food-producing algae living in their tissues, breaking down their symbiotic relationship and leading to loss of colour and life in the process known as bleaching.

Recent spikes in tropical and sub-tropical sea surface temperatures, magnified by an especially potent El Nino, have triggered an unprecedented mass bleaching of corals, affecting 75 percent of global reefs.
The Intergovernmental Panel on Climate Change in 2018 issued its landmark report on the Paris deal temperature goals -- "well below" two degrees Celsius (3.6 Fahrenheit) above pre-industrial levels and a cap of 1.5C if at all possible.
It found that at 1.5C hotter, more than 70 percent of Earth's coral reefs will likely die off. At 2C, that increases to 99 percent.
But the discovery that certain types of corals can recover from being exposed to long heatwaves offers a "glimmer of hope" for the rich marine ecosystem, the authors said in the study.
The results show local protection strategies can have an impact on saving the corals, providing incentive to continue efforts to protect reefs.
"If we are to save these magnificent ecosystems overall, the world must get climate change under control," said Baum.
"But this new discovery... might buy some corals a bit of time under climate change."

Global Warning: North Pole is Heating Up Twice as Fast as the Rest of the Earth

The sea ice floating the Arctic ocean melts in summer and freezes again in winter. The problem is each year it is melting a bit more in the warm weather and refreezing a bit less.

LAST UPDATED :
DECEMBER 09, 2020, 08:30 IST

Every year for the past 15, environmental scientists working under the aegis of a US government agency issue a report on the state of the Arctic, and Tuesday's edition confirms an alarming trend: the North Pole is heating up twice as fast as the rest of the planet.
The year 2020 did not beat the record set in 2012, but it got so close there is no reason to feel encouraged.


The sea ice floating the Arctic ocean melts in summer and freezes again in winter. The problem is each year it is melting a bit more in the warm weather and refreezing a bit less.
Scientists now get reliable data as satellites have been photographing and measuring the Arctic non-stop since 1979.

And there is no room for doubt about the region's melting pattern. 2020's late summer thaw was the second-worst year on record after 2012: compared to its highest historical level, half of the sea ice is now gone.
Since 2010 a new generation of satellites is capable of measuring the thickness of the ice and here the news is also grim. The ice is thinner, younger and more fragile.

The report released Tuesday, called the Arctic Report Card 2020 and published by the National Oceanographic and Atmospheric Administration, provides a wealth of information that illustrate the complexity of the Arctic climate system.
The climate in the rest of the world -- wind and currents -- affects what happens at the North Pole, while the South Pole is comparatively more isolated.


MELTING, ABOVE AND BELOW

This complexity is seen in a statistic tucked away on page 13 of the report: Alaska's North Slope experienced its coldest February in 30 years and it was also colder than usual in Svalbard, Norway.

But Siberia set heat records, with temperatures 3-5 degrees Celsius (5.4 to 9 degrees Fahrenheit) above normal, and the region suffered terrible wildfires in the spring.
The air temperature at the surface of the Arctic over the course of 2019-2020 was 1.9 degrees Celsius (3.4 Fahrenheit) higher than the average for the period 1981-2010, making it the second hottest year on record since 1900.
The phenomenon of "Arctic amplification," which causes this region to heat up faster than other parts of the world, is in full force.
The Arctic ocean is also heating up: in August of this year the water was between 1 and 3 degrees Celsius (1.8 and 5.4 Fahrenheit) hotter at the surface than the average for 1982-2010.
Here, too, events are linked and fuel each other. When ice melts and exposes the ocean, the water absorbs more heat from the sun, which in turn worsens the melting of the sea ice, although this time from underneath.

"One of the things that's important to realize about the Arctic is it's a system. It's a system of interconnected components," said Donald Perovich, a professor of engineering at Dartmouth University and co-author of the sea ice chapter in the NOAA report.
"You can change one thing, those changes cascade through the whole system," he said.
Sea ice is both an indicator and amplifier of global warming.
Its melting does not contribute directly to rising sea levels, as this ice is already in the water. But the melting does contribute indirectly by heating up the water.
For Arctic researchers the true shock came in September of 2007, when the summer melt of the sea ice was extreme. (Since then, 2012 broke the record.)
"We never returned to the levels we saw in 2006 or earlier," said Perovich. "We're in this new regime"
Models forecast that there will no longer be any sea ice in summer in the Arctic starting between 2040 and 2060.
Back in the first edition of this report in 2006, researchers were still not sure of the Arctic heating trend. They expressed doubt that permafrost -- soil that is frozen year round -- could melt in the north of Alaska.
Now, those same researchers say "it is anticipated that progressive deep thawing of permafrost in this region may begin in 30-40 years."
