Abstract
It is widely acknowledged that the frequent occurrences of extreme weather are closely related to global warming.The aerosol optical depth is the main cause of the change for the temperature.The present research region is in（30-50 °E,70-80 °N）of the Barents Sea.The distribution and coupled relation of AOD and ICE in the research region from 2003 to 2009 are analyzed.According to the integrated statistics of seven years,AOD was very high in spring,and then went down in summer,increased in the fall again.AOD was higher in south than that of the North.But in 75-80° N,AOD was particularly high in 2003.AOD and ICE have a good coupling relationship with a lag of one month（ICE was one month ahead of AOD） in the study region.Eviews is used to do regression analysis.After shifting AOD one month ahead,the correlation coefficient between ICE and AOD is about 0.5 in the northern part,while is about 0.30 in the southern part.The ice peak is a little earlier than the peak of AOD,indicating the melting of sea ice results in biological reduction of sulfur species,leading to the increase in AOD content.The AOD in smaller area（30-35°E,70-75°N） for 13 years（1998—2009） time series are also studied and the stable white noise time series is used to predict the future time series of AOD.关键词
