Scientists stated that weather condition or climate change could be adjusting the jet stream in a way that prompts heavy flooding, dry seasons, heat waves, and other intense climate effects. It appears that man-made climate change is not only prompting more intense climate or weather by usual mechanisms, including warm temperatures and additional air moisture.
Pennsylvania State University's Dr. Michael Mann and his partners announced that climate change is straightforwardly affecting intense weather events by means of changing the jet stream's movement, Phys stated. Jet streams, strip-like air currents and flows across the northern part of the globe up to 7 miles over Earth's surface, are driven by conflicting cool polar air and tropical climes. The path of these extreme air streams forms weather design, like, pressure systems that prompt hot or cold spells.
The team proposed that the climate-driven change in the jet stream influence particular occasions or events, the 2003 European heat wave, the Pakistan flooding and a Russian heat wave in 2010, and the 2011 Texas heat wave. The team searches for historical atmospheric data to better check the conditions under which these intense events formed and proceeded. They saw that these happened when the jet stream turned stationary, the pinnacles and troughs remaining secured.
Just lately, the National Snow and Ice Data Center in Colorado announced that Arctic sea ice levels have come down to a record low of 5.57 million square miles, Techtimes cited.Most of the change, as well, has happened in the previous 40 years, rendering the persistent, regularly happening winding jet stream a quite recent event.
"The warming of the Arctic, the polar intensification of warming, assumes a key part here," said Mann in an announcement. "The surface and lower atmosphere are warming more in the Arctic than anyplace else on the globe." The Arctic has warmed over twice as fast over the past half-century as the worldwide temperature average, moving by 3.6 degrees Fahrenheit. Air floating over land masses, as well, has warmed more quickly than over the world's oceans.
