Winter Weather 2023 23 – The U.S. GFS model predicts colder-than-average temperatures in the eastern United States over the next two weeks. (climate)

In mid-February, temperatures between 10 and 30 miles above the North Pole soared to 50 degrees, setting off a chain reaction that is already affecting North America. Known as the “sudden stratospheric warming” event, sudden warming of the stratosphere, the second layer of Earth’s atmosphere, disrupted the storm and caused its destruction.

Since that episode three weeks ago, a series of dominoes have changed weather patterns in North America. Now it looks like the eastern part of the United States.

Normally, the development of high pressure over Greenland – the classic answer to the polar vortex disruption problem – helps displace cold Arctic air and push it southward. The Arctic has changed dramatically in many areas, as freezing temperatures have reached the eastern United States, all as a winter storm prepares to move from the northwest into the Midwest and west-central Atlantic.

It arrives as the calendar inches ever closer to spring weather, but winter may not be ready to give up. Scientists believe the polar vortex is already having its impact and that the afterglow could be on the horizon.

The stratospheric polar vortex is like a violent air current located at two or three times the altitude of commercial airliners. Colder temperatures over the North Pole, caused by a lack of sunlight, cause the air column to thicken and narrow over land. This creates a kind of vacuum in the upper atmosphere, which becomes a gas-like atmosphere. As the atmosphere rotates clockwise, it cools, repeating the same process.

The stronger the storm, the faster it moves. This causes the Arctic to cool at high altitudes. But if something happens to weaken the wind or stop its flow, then the wind chill lobes can slide toward the center.

It takes weeks, but after any disruption of the polar vortex or sudden warming of the stratosphere, the effects can begin to show up in the lower atmosphere.

In an email, Simon Lee, a meteorologist at Columbia University, wrote: “It is common for a long time to pass between onset and visible effects in the atmosphere.”

Lee said the sudden stratospheric warming came in two forms: first, a reversal of the stratospheric polar vortex on February 16, then a doubling of the dip in that wind at the end of the month.

Long Range Weather Forecast For 2023

“[The events of February 16] were initially too short and too long to have much impact, but once confirmed, things changed,” Lee wrote.

Scientists are spotting a number of signs that the sudden warming of the stratosphere is starting to shape the atmosphere at the core.

First, a weak polar vortex contributed to a negative AO, or Arctic Oscillation. When the AO is positive, cold air tends to move over the Arctic because storms are stronger and more stable. But when the AO fluctuates negatively, it means winds are disturbed and the gates are open for Arctic air to flow southward.

Judah Cohen, a meteorologist specializing in climate and environmental research, compared the unique effects of the polar vortex in the mid-equatorial atmosphere to a “drop of paint,” each drop representing the appearance of cold air and potentially cloudy skies. He says one is already hitting the northern US, writing in a direct message on Twitter that the models “also show some other effects that will fade or fade over the course of the week, [indicating there may be more”

Secondly, the “Greenland blockade” was established. One of the signs of sudden stratospheric warming is the formation of this block, which is a vertical dome of high pressure near Greenland. It changes the jet stream in southeastern North America, allowing cold Arctic air to flow southward.

Although much of the eastern United States has experienced extreme temperatures since the December holidays, the cold weather is starting to abate. For the next 6 to 10 days, the National Weather Service has a “high probability” forecast for the East. of subtropical temperatures and requires cooler than usual weather until early April.

Additionally, the presence of high pressure may cause traffic jams in the opposite direction, keeping the season winds above average in the East. If this does not happen, the signs of stretching will not disappear for the next two weeks. Forecast models show the possibility of a mix of rain and snow from the storm system late this week and early next in parts of the Mid-Atlantic and Northeast.

On the phone, Cohen explained that the effects of the storm’s impact likely began at least a week ago.

“I think we’ve already seen the impact,” he said. “We had the means to put pressure on Western Russia and Eastern Europe. A little cold and snow. We also saw a closed-end fund trying to develop in Canadian maritime areas. Boston, New York and DC It hasn’t snowed much, but in New York’s English restaurants it has. “

He said some of the ice in northern England was caused by rapid melting at the end of February after the melt itself.

“Portland, Maine, under normal [snow] conditions,” he said. “I think this had an immediate effect on the polar disturbance,” he said.

But one thing is clear against snow, which is a nuisance for winter lovers: the weather. The days grow longer, the sun’s rays grow longer, and the whispers of summer begin to float in the air.

Winter returns. After last year’s unusually warm weather, cold temperatures and snow will return to the United States at the same time. (Be sure to read the weather tips below.)

December 2023 is expected to be the start of the storm.

There are indications that El Niño (unusual water temperature on the Pacific coast of South America) will warm from the end of 2023 until the winter of 2024. If we verify this with the tested experiments. Weather forecast, which means cold temperatures are expected to prevail across the country and bring snow, ice and snow.

The broadest forecast, based on numbers and weather data, calls for lower-than-average temperatures and more snow, sleet, sleet and rain across much of the Great Lakes and the Midwest, as well as central and northern New England, especially in January and February. (Brrr…)

Snowfall and unusual temperatures are also expected in the Pacific Northwest. If El Niño proves effective, it could bring the subtropical jet to California, creating another wet and dry winter that would keep California and the Southwest drought-free.

Winter in the Great Plains and Rocky Mountains will bring high temperatures and occasional cold spells, bringing heavy rain and snow.
