Severe winter weather as a response to the lowest Arctic sea-ice anomalies

摘要: Possible impact of reduced Arctic sea-ice on winter severe weather in China is investigated regarding the snowstorm over southern China in January 2008.The sea-ice conditions in the summer(July-September) and fall(September-November)of 2007 show that the sea-ice is the lowest that year.During the summer and fall of 2007,sea ice displayed a significant decrease in the East Siberian,the northern Chukchi Sea, the western Beaufort Sea,the Barents Sea,and the Kara Sea.A ECHAM5.4 atmospheric general circulation model is forced with realistic sea-ice conditions and strong thermal responses with warmer surface air temperature and higher-than-normal heat flux associated with the sea-ice anomalies are found.The model shows remote atmospheric responses over East Asia in January 2008,which result in severe snowstorm over southern China.Strong water-vapor transported from the Bay of Bengal and from the Pacific Ocean related to Arctic sea-ice anomalies in the fall(instead of summer)of 2007 is considered as one of the main causes of the snowstorm formation.Abstract: Possible impact of reduced Arctic sea-ice on winter severe weather in China is investigated regarding the snowstorm over southern China in January 2008.The sea-ice conditions in the summer(July-September) and fall(September-November)of 2007 show that the sea-ice is the lowest that year.During the summer and fall of 2007,sea ice displayed a significant decrease in the East Siberian,the northern Chukchi Sea, the western Beaufort Sea,the Barents Sea,and the Kara Sea.A ECHAM5.4 atmospheric general circulation model is forced with realistic sea-ice conditions and strong thermal responses with warmer surface air temperature and higher-than-normal heat flux associated with the sea-ice anomalies are found.The model shows remote atmospheric responses over East Asia in January 2008,which result in severe snowstorm over southern China.Strong water-vapor transported from the Bay of Bengal and from the Pacific Ocean related to Arctic sea-ice anomalies in the fall(instead of summer)of 2007 is considered as one of the main causes of the snowstorm formation.
