Scientists have found that pollution coming from Asian countries is affecting weather in the United States . The effect that pollution in Asia may have on other parts of the world has been examined by both NASA 's Jet Propulsion Lab ( JPL ) and the California Institute of Technology , NASA 's Earth Science News reported . Jonathan Jiang , who is part of JPL , and Yuan Wang looked at the potential link between more intense storms in the Northwest Pacific , deeper clouds over the Pacific Ocean , and Asia 's period of economic growth -- all of which happened in the same 30-year period , according to the news outlet .

'We found that pollution from China affects cloud development in the North Pacific and strengthens extratropical cyclones , ' Wang , who is a postdoctoral fellow , told Earth Science News . Jonathan Jiang , pictured , was one of the researchers involved in the project . Wang told the news outlet that more powerful extratropical cyclones likely played a role in 2013 winter weather on the East Coast . He also said that during extratropical cyclones , a larger amount of water undergoes condensation on aerosols -- due to greater pollution . Heat released from the process can contribute to a cloud becoming both larger and deeper , Earth Science News explained . Jiang told the news outlet 'Before , we thought about the North-South contrast : the Northern Hemisphere has more land , the Southern Hemisphere has more ocean . 'That difference is important to global atmospheric circulation . 'Now , in addition to that , there 's a West-East contrast . Europe and North America are reducing emissions ; Asia is increasing them . 'That change also affects the global circulation and perturbs the climate . ' Speaking to the Weather Channel , Jiang said 'During the wintertime , human-induced pollution such as coal burning in many Asian cities can create smog that lasts for weeks . Cold conditions : Postdoctoral fellow Yuan Wang has said that more powerful extratropical cyclones likely played a role in 2013 winter weather in the East . ( A woman is seen in Boston in this February 2013 file photo ) 'Under favorable wind conditions , pollution particles can be transported downwind across the North Pacific , where winter storms are prevalent . ' However , Jiang told NPR that he does not know to what extent powerful Pacific storms can cause severe weather in other parts of the United States . 'We have not reached a final conclusion yet , ' he told the media outlet .
