It’s snow all over the East Coast. More than 5000 flights have been cancelled as the strong nor’easter has severely affected places like New Jersey, Boston.
A nor’easter makes any winter crueler. This storm massively hits the Northeast and drew the name from there. It requires huge energy and this energy essentially comes when the extremely cold Arctic air bumps onto the warm water of the Gulf Stream. When the atmosphere turns warmer, it tends to hold more moisture is by that increasing the possibility of more snowfall if the temperature stays enough cold.
Climatologist Michael Mann suggested that the constant changes in the climate caused by human interference contribute significantly to the development of such destructive nor’easter. The rise in ocean temperature is mostly due to the intense lack of human awareness, he added.
Kevin Trenberth, climate scientist from the National Center for Atmospheric Research explained that presently the surface temperature of the sea is more than 2 F above normal range and the effect is seen over 1000 miles off the east coast. As a result of this, the atmosphere is holding around 10 percent more water vapor; half of which is likely to arise from climate change. Under these circumstances, more snowfall can be predicated, say experts.
Strangely enough, the more warm the world turns, wetter it will be. Also, rainfalls will be heavier in coming days. Frequent floods may occur especially in the coastal areas.
And with required cold temperature, a warmer atmosphere will cause giant snowfalls. But making any prediction about snowfall within a particular region is more difficult because it can be highly specific to the locations and also a lot of other environmental factors may affect the optimum conditions required for snowfall.
Scientists believe that in a warmer world, there would be less occurrence of cyclones, but the fewer they become, the more dangerous they are likely to be.
Future research will shed more light to understand the long-term effects of global warming on such atmospheric events.
