Arctic has been going through a transition from solid precipitation to liquid precipitation in spring

Temperature and precipitation history of the Arctic

As the planet cooled from peak warmth in the early Cenozoic, extensive Northern Hemisphere ice sheets developed by 2.6 Ma ago, leading to changes in the circulation of both the atmosphere and oceans. From w2.6 to w1.0 Ma ago, ice sheets came and went about every 41 ka, in pace with cycles in the tilt of Earth’s axis, but for the past 700 ka, glacial cycles have been longer, lasting w100 ka, sep...

On the El-Niño Teleconnection to Spring Precipitation in Europe

Abstract In a statisti al analysis of more than a entury of data we nd a strong onne tion between strong warm El Ni~ no winter events and high spring pre ipitation in a band from Southern England eastwards into Asia. This relationship is an extension of the onne tion mentioned by Kiladis and Diaz (1989), and mu h stronger than the winter season tele onne tion that has been the subje t of other ...

Influence of sea ice on Arctic precipitation.

Global climate is influenced by the Arctic hydrologic cycle, which is, in part, regulated by sea ice through its control on evaporation and precipitation. However, the quantitative link between precipitation and sea ice extent is poorly constrained. Here we present observational evidence for the response of precipitation to sea ice reduction and assess the sensitivity of the response. Changes i...

Discrimination of Solid from Liquid Precipitation over Northern Eurasia Using Surface

Discrimination of Solid from Liquid Precipitation over Northern Eurasia Using Surface Atmospheric Conditions*

Daily synoptic observations were examined to determine the critical air temperatures and dewpoints that separate solid versus liquid precipitation for the fall and spring seasons at 547 stations over northern Eurasia. The authors found that critical air temperatures are highly geographically dependent, ranging from 21.08 to 2.58C, with the majority of stations over European Russia ranging from ...
