渤海海冰与西伯利亚高压之间的关系及与北大西洋涛动之间的可能联系
Relationships Between Bohai Sea Ice and Siberian High and Possible Connections Between Bohai Sea Ice and North Atlantic Oscillation
摘要
Abstract
After analyzing the relationship between Sea Level Pressure (SLP) and Bohai sea ice extent during the winter of 2000/2001-2014/2015 on the intra-seasonal and inter-annual scales,three main correlation areas were found around Siberian High(positive),Iceland Low(positive) and Azores High(negative).Siberia high affects Bohai sea ice both in intra-seasonal and inter-annual scales,and the correlation between North Atlantic Oscillation(NAO) and Bohai sea ice is mainly on the inter-annual scale.Research shows that the Bohai sea has remarkable cycle of 9~12 pentads in 2003/2004,2004/2005 and 2007/2008.This cycle disappear after 2009/2010,but the Siberia high SLP still maintain a period of 9~12 pentads,which can be explained the season why the correlation coefficient between Siberian High and sea ice extent reduced significantly after the winter of 2009/2010.On the inter-annual scale,the correlation coefficient between NAO and sea ice extent increased rapidly after 2007/2008 due to the same periodic variation of 2~4 years and 4~8 years of NAO and Bohai air temperature.This shift may have a influence on Bohai sea ice extent through the Arctic-Asian teleconnection pattern.关键词
