Excessively Cold Winter May Be Caused by New Type of Jet Stream
There is a new research study that has been done by scientists in Chicago, which has determined that the excessively snowy and cold winter weather that has happened so far in the United States and Canada, and the powerful rain storms over Europe and the United Kingdom, is being caused by a new type of twisting jet stream that could be here for good.
The scientific study has shown that the North Atlantic jet stream has progressively started to take a lengthier and curvier path. Ordinarily the jet stream, a fast moving, thin current of air, goes from the region of the Gulf of Mexico and goes to the north east. It typically brings mild, wet, windy weather to the areas in its route.
During the hurricane season in areas of the southern region of the United States, numerous hurricanes begin losing their strength as they move over cooler sections of the Atlantic Ocean and end as storms up in Scotland or Ireland. However, there has been something drastic happen in the past year. The winter season in the northern hemisphere has experienced powerful snow storms over Canada and the U.S. and there have been devastating storms and thick rains which have caused floods across wide regions of the U.K. The north part of Spain has even been struck by a full year’s amount of rainfall dropping in only the winter months.
There was a noticeable absence of hurricanes during the 2013 season, so apparently what happened and changed to create all of the strange modification in the weather arrays? The American Association for the Advancement of Science, which is located in Chicago, stated that the Arctic region is heating up at three times the quickness of the entire rest of the Earth.
It could also be that the strong typhoon Haiyan, which occurred in November 2013 in the Philippines, changed the weather patterns in a flowing vortex or air current which goes all the way from that area of the world to the Canadian Arctic area. This produced the lethal “polar vortex” that sent down severely cold weather from that Arctic region to Canada and the United States and caused snow to fall as far south as Texas and Georgia.
In the meantime, the jet stream, which first starts on the western coast of Africa, never is able to quite reach the Gulf or even the mainland of America and instead simply creates great storms that are hundreds of miles away from Florida and the Carolinas and instead head for Britain.
What is able to give the jet stream such power is the huge alteration between the Arctic and the middle latitude zones. As the Arctic heats, it caused the jet stream to weaken and cause it to ramble and hang around a lot longer than it usually would. The United Kingdom has been hit by storm after storm since the first part of December of 2013, which is almost three months ago now. This is about the same amount of time the United States has suffered from extremely icy cold conditions.
