Weather forecasting as practiced by national meteorological services is almost wholly dependent on charts prepared from observations of weather made over large areas a few hours at most before the forecasts are issued. Rapid and reliable communication facilities are prime necessities in such work. There...
THE Deutsche Seewarte, Hamburg, has undertaken to produce on behalf of the International Meteorological Organisation, daily synoptic weather charts covering the whole of the northern hemisphere. It is not intended to produce a synoptic chart differing from those published daily by the British ...
Weather regimes and the location of the northern hemisphere polar jet stream, hereinafter referred to as jet stream, interact with each other. Specific weather regimes are associated with a northern, central or southern position of the jet stream. Therefore, we investigate whether the relationship ...
Summer heat anomalies in the northern hemisphere will become more persistent in the midlatitudes, especially in southern North America where summer weather patterns and associated temperature anomalies are projected to slow-down by more than 45% by the end of the century There are robust relationships...
Southern parts of Germany suffered a walloping of snow on Wednesday, while the German Weather Service (DWD) forecast snow through next week, primarily in the Alpine region. About 350 people are still trapped in Berchtesgaden, a small town in the German southern area, and the affected residents...
With summer just around the corner, the Northern Hemisphere isn't waiting until June 21 for the heat to arrive. On the other side of the globe, a blistering heat wave in Pakistan resulted in Jacobabad hitting 51°C on Saturday -- the hottest temperature on ...
Researchers from the Chinese Academy of Meteorological Sciences, the Institute of Atmospheric Physics under the Chinese Academy of Sciences as well as other institutions analyzed the temperature data of the northern hemisphere from 1960 to 2012 and calculated the "compound hot extremes," referring to ...
98and polar regions99of the Southern Hemisphere. Our method has the potential of revealing new and previously unknown weather patterns that are relevant in such regions, thus potentially advancing our knowledge of regional climate and facilitating the evaluation of the impacts of climate variability on...
One idea for mid-latitude seasons would be to have the following season structure: Summer: June through September (4 months), Fall: October and November (2 months), Winter: December through March (4 months) and Spring: April and May (2 months). This season structure would fit the temperat...
