A Warmer Winter For The United States Due To El-Nino And Climate Change

While El Nino is the biggest factor in the forecast, long-term warming from human-caused climate change is a factor.

Winter looks wet and especially mild for much of the country, thanks to a weak El Nino brewing, U.S. meteorologists said.

The National Weather Service on Thursday predicted a warmer than normal winter for the northern and western three-quarters of the nation. The greatest chance for warmer than normal winter weather is in Alaska, the Pacific Northwest, Montana, northern Wyoming and western North Dakota.

No place in the United States is expected to be colder than normal, said Mike Halpert, deputy director of the government’s Climate Prediction Center.

The Southeast, Ohio Valley and mid-Atlantic can go any which way on temperature, Halpert said.

Overall the winter looks a lot like the last few, Halpert said.

“The country as a whole has been quite mild since 2014-2015,” Halpert said.

Winter weather expert Judah Cohen, of the private company Atmospheric and Environmental Research, uses different indicators to predict winter for the National Science Foundation. He also forecasted a warm winter, heavily based on weak snowfall in Siberia.

Precipitation

Halpert said the southern one-third of the United States and much of the East Coast could be hunkering down for a wetter than normal December through January. The chances are highest in southeastern Georgia and much of northern and central Florida.

Hawaii, Montana, Michigan, parts of Idaho, Wisconsin, northern Illinois, Indiana and Ohio are forecast to be drier than normal, with the biggest likelihood in Hawaii, Montana and Michigan.

The middle belt of the nation and some of the north from California to New York can go any which way on precipitation.

The weather service’s forecast doesn’t look at snow likelihood.

El Nino

Halpert said the biggest factor in the forecast is a likely El Nino , the natural warming of parts of the central Pacific Ocean that influences weather worldwide.

The El Nino hasn’t quite formed yet, but it’s almost warm enough. Meteorologists predict there’s a 75 percent chance it’ll be around this winter. But it will be weak, not strong like the El Nino that helped lead to the record warm 2015-2016 winter, Halpert said.

Background warming

While El Nino is the biggest factor in the forecast, long-term warming from human-caused climate change is a factor, too, Halpert said.

“All things being equal, the slight kick we get out of the climate signal does tilt things toward the warm side,” Halpert said.

But it’s not enough to outweigh other factors if they push toward cold.

“Even on a warming planet,” he said, “it doesn’t mean winter goes away and it’s never cold again.” (VOA)

Paris will restrict car use on Wednesday as a measure to fight against surging air pollution linked to intense heat wave that strikes most of French regions, the city’s police department announced on Tuesday.

Only electric vehicles and those with clean air stickers 1 and 2 are allowed to enter the French capital on June 26 from 5:30 a.m. local time to midnight, Paris police prefecture said.

Called also Crit’Air vignettes, the stickers have six colours that identify the emissions the vehicle produces according to the European emissions standard, the Xinhua news agency reported.

The other vehicles, mostly older and diesel cars, will be preventing from circulating in Paris following the unusual heatwave.

Amid expected high level of ozone pollution linked to rising temperatures, speed limits will also be cut by 20 kilometer per hour in Paris and Ile-de-France on Wednesday, while vehicles weighing over 3.5 tonnes will be asked to bypass the city centre and nearby surroundings completely.

Furthermore, Paris police department called on businesses that use polluting machinery to reduce operations, and avoid using solvent-based products, such as acetone, varnishes, glues or paints.

Like major Western European countries where unprecedented high temperatures will appear in at least the next six days, France is set to witness unseasonable temperatures which could even exceed 38 degrees Celsius in parts of eastern and southern regions in the coming days.

For Wednesday, Meteo France predicts 34 degrees Celsius in the French capital. Temperature could reach up to 39 degrees by Friday afternoon.

Meteo France has put 65 departments, including Ile-de-France (Paris and its suburb), under orange alert due to intense heatwave and decided to maintain the alert system in these areas till Wednesday afternoon. (IANS)
