Arctic warming and US winters

Arctic warming and US winters depict that northeastern United States is getting more snow laden. Just over a period of time three winter storms impacted into the northeast from Washington, D.C., to Boston.

Over the last decade, a gust of paramount winter storms has hit the region forming a portmanteau names such as Snowpocalypse (2009), Snowmageddon (2010) and Snowzilla (2016). Researchers have prior to this proposed that dangerous weather in mid-latitudes may be related climate change’s impression on the Arctic, especially the conspicuously diminished sea ice cover in the Arctic Ocean. And presently, a study published online in Nature Communications reports a robust relation between the extreme winter weather knowledgeable in the northeastern United States over the last decade and the warming shift in the Arctic.


Climatologist Judah Cohen of the Massachusetts-based climate and weather risk assessment group Atmospheric and Environmental Research and atmospheric scientist Jennifer Francis of Rutgers University, have been advocates of the hypothesis that the warming Arctic is having massive effect on weather at the mid-latitudes from critical snowfalls to scorching heat waves.

It was Francis who propagated in 2012 that sea ice diminution in the Arctic decelerates the Polar Jet Stream, a band of air currents proceeding above the northern and middle latitudes of Earth. The decelerated jet stream would become abandoned, with massive meanders that might project bottomless into the mid-latitudes. Such waves would permit winter storms to thrust south and linger.

The idea was captivating especially coming in the form of two massive snowstorms in the northeastern United States. However, many scientists were dubious, proposing that the repressed atmospheric dynamics, how diminishing sea ice in the far north might configure mid-latitude weather, remained unsure. Researchers have pursued to argue over this question.
