Teleconnection

from Wikipedia, the free encyclopedia

In meteorology, teleconnection is a connection between weather processes in two areas that are far apart from each other.

The relationships relate, for example, to the opposing behavior of air pressure or temperature . So z. B. a tendency towards opposite air pressure between Iceland and the Azores . This means that the lower the air pressure over Iceland, the higher it is (over a longer time interval , about a month, averaged) over the Azores and vice versa. This phenomenon is known as the North Atlantic Oscillation . Likewise, on average in winter, below normal temperatures in the Eastern Canada / Greenland area are associated with above normal temperatures over Europe .

The teleconnections known today are used to determine that irregularities in one part of the world correlate with others, either directly or with a delay, so that extreme weather conditions often accumulate worldwide. Today the El Niño cycle of the Pacific is considered to be one of the fundamental “weather engines” that has an impact worldwide in intensive phases, while the Gulf Stream , for example, is considered to be a stabilizing system.
