And a second one that explains the cold
Eurasian winters, but without affecting the global mean temperature.
And
the Eurasian winter cooling could be a separate, superimposed effect, with no impact on global mean temperature and hence nothing to do with the «pause».
A central topic will be teleconnections in the climate system, i.e. how a change in climate in one part of the globe (e.g. temperatures in the Atlantic or shrinking sea ice cover in the Arctic) can influence climate on other parts of the globe (e.g.
Eurasian winter temperatures), and how we can use this information to improve regional climate prediction and therefore regional climate service.

The property makes a critical contribution to the conservation of the natural values within the Great Rift Valley, as an integral part of the most important route of the African -
Eurasian flyway system where billions of birds are found to travel from northern breeding grounds to African
wintering places.
If this Arctic
winter was expansive deeply southwards, bi-continental in size, on
Eurasian and North American side at once, no way it would have materialized.
Judah has been publishing on the link between

winter for quite some time.

It is found that
winter sea ice is about 50 cm thinner in high - NAO index years than in low - NAO index years in the
Eurasian coastal region mainly due to stronger wind - driven ice export.
The speed of formation of the
Eurasian snowfield is correlated with a stronger
winter Siberian high and migration into the Arctic.
NSF - funded research has shown that variability in the extent of
Eurasian snow cover can be used to predict cold or warm
winters across the entire mid-latitudes of the Northern Hemisphere.
Or Arctic sea ice loss could lead to an increase of snow on high - latitude land, which in turn impacts the jet stream resulting in cold
Eurasian and North American
winters.
The dust - induced thermal contrast changes between the
Eurasian continent and the surrounding oceans are found to trigger or modulate a rapidly varying or unstable Asian
winter monsoon circulation, with a feedback to reduce the dust emission from its sources (Zhang et al., 2002).
Therefore, we suggest that a significant portion of the wintertime temperature trend is driven by dynamical interactions between October
Eurasian snow cover, which has increased over the last two decades, and the large - scale NH extratropical circulation in the late autumn and
winter.
Physically, one could expect a slight decrease in surface evaporation (a «dimming» effect) and related changes to precipitation, a warming of the tropopause and lower stratosphere (and changes in static stability), increased
Eurasian «
winter warming» effects (related to shifts in the wind patterns as are seen in the aftermath ofvolcanoes).

Most of the proposed mechanisms linking reduced sea ice and / or increased
Eurasian snowcover to extreme
winter weather across mid-latitude NH continents involve a pathway through the SPV6, 24,25,32,33,55,56,57.
