The effects of the “Major Stratwarming” started to emerge in the troposphere, Canada and the U.S. are preparing for the cold by by Daniel Ingemi

Only now, in the troposphere, you begin to feel the effects of the powerful “Stratwarming” earlier this month that it is on top of the Arctic Ocean. The sudden warming of the stratosphere in the coming weeks could cause a real disruption in the troposphere, favoring the occurrence of major cold spells in the area of Canada, the northern United States, along with European countries and those of central and northern Asia .
In general, the “Stratwarming” probably begins to occur when the hemispheric general circulation begins to present a trend rather wavy, for the development of “forcing” tropospheric more and more intense, especially between the North Pacific and North Atlantic, where go to build impressive “blocking” (cliffs anticyclonic blocking, lying along the meridians) that stop the raging current neighborhood. In this phase above the Arctic latitudes, because of the intense “forcing” the upper troposphere, may occur of the intense heating stratospheric that tend to propagate towards the upper troposphere, favoring an appreciable increase of geopotential values ranging to establish a powerful cell dynamics tropospheric anticyclone over the Arctic.
But most likely, these sudden and intense overheating of the stratosphere over the Arctic, can be induced also sensitive to variations in solar activity, given the particular interaction that exists between the solar radiation and the ozone layer in the stratosphere existing. We must consider that in an event of “Major Stratwarming” strong enough, temperatures in the Arctic lower stratosphere can increase dramatically, even +50 ° C +60 ° C than the standard values. A thermal anomaly positive truly impressive that produces a real upheaval baric on the troposphere below. The mechanism is always the same.
