The event occurred in early 2014 and was caused by a southward shift of the North Polar Vortex. Updated Jan. 31 at 9:48 a.m. The swirling air can bring high winds and a lot of precipitation, often in the form of snow. But one impact of the storm is even more clear: After it eventually moves off to the north and west, it should draw even more cold polar air into the eastern half of the United States, continuing the big chill. "There is pretty good evidence of correlation between November patterns and December to February aggregate patterns, both via temperature correlations and via correlations between various teleconnections, like the Arctic Oscillation and North Atlantic Oscillation," Crawford said in an email. Studies suggest the jet stream is weakening, causing Arctic air to dip south. Ordinarily the jet stream is straight, blowing from west to east. Why Is Record Cold and Epic Snow Hitting U.S. CNN’s Holmes Lybrand, Brandon Miller and Ryan Smith contributed to this story. Winter is a fascinating time of year and we've got 8 interesting facts about the season.

Much of California and southern portions of Arizona, New Mexico and Texas are other places that have moderate to strong relationships between November temperatures and December to February temperatures. As residents of those regions are well aware, November has been quite cold so far, and hundreds of additional record-cold temperatures for mid-November are in jeopardy through Thursday. Is this unusual? Some scientists studying the connection between climate change and cold spells, which occur when cold Arctic air dips south, say that they may be related. In a bomb cyclone, the temperature difference between the two air masses leads to a steep and rapid — meteorologists often use the term “explosive” — drop in atmospheric pressure. For the past three weeks, cold and snow have eluded most of the Lower 48 states. Winter temperature outlook for December-February 2018-2019 issued on November 15, 2018.

That’s why your secret organization releases it in the winter. There are two different dates when winter could be said to begin, depending on whether we are referring to the Meteorological or Astronomical winter. She is the lead author of a study published last fall that looked at four decades of climate data and concluded that the jet stream — usually referred to as the polar vortex this time of year — is weakening more frequently and staying weaker for longer periods of time.

This was enough for 2018-19 to be categorized as a "severe" winter. Question Why is it hot in summer and cold in winter? Winter is coming. “When we have a weak temperature gradient between the Arctic and mid-latitudes, the result is weaker winds,” he said. But scientists have been puzzled by data that at first seems counterintuitive: Despite an undeniable overall year-round warming trend, winters in North America and Europe have trended cooler over the past quarter-century. The air starts to move and, aided by the earth’s rotation, begins to rotate. The reason a direct connection between cold weather and global warming is still up for debate, scientists say, is that there are many other factors involved. “But the exact connection on the climate scale is an area of active research.” Much of the Northern Hemisphere is cold this time of year (it’s winter, after all). A total of 664 hospital admissions and 85 confirmed deaths have been reported since the beginning of winter 2017. Blame the polar vortex, the jet stream, the lake effect—and a typhoon. The Arctic is not as cold as it used to be — the region is warming faster than any other — and studies suggest that this warming is weakening the jet stream, which ordinarily acts like a giant lasso, corralling cold air around the pole. Cold snaps have occurred throughout history — certainly long before industrialization resulted in large emissions of greenhouse gases. And that's thanks to a protective gel-like coating that surrounds the flu virus while it's in … Want the latest climate news in your inbox? But the study focused on Europe and Russia.
