云南寒潮与昆明准静止锋的气候关联性分析
The Climate Correlation Analysis between the Cold Wave in Yunnan and Kunming Quasi-Stationary Front
摘要
Abstract
Based on daily mean temperature and minimum temperature of 122 meteorological observation stations in Yunnan and daily ground observation stations data of Yunnan-Guizhou Plateau from 1961 to 2010,The climate correlation between the Cold Wave (CW) in Yunnan and Kunming Quasi-Stationary Front (KQSF) is analyzed.The results show:①The more CW frequency region over Yunnan is mainly located in the east side of the KQSF average position(the back of KQSF).②The interdecadal change of Yunnan CW frequency is basically opposite to the KQSF.The Yunnan CW frequency has decreased in nearly 50 years and from more than mean period to less in near 1985.The KQSF frequency has increased in nearly 50 years and from less than mean period to more in near 2002.The annual change has obviously positive correlation between CW and KQSF,especially in the winter.When the CW frequency is more(less) than the normal,the KQSF frequency is also more(less) than the normal.The relationship is closer in the east side of the KQSF (the back of KQSF).③The interdecadal change of Yunnan CW frequency is basically consistent with the mean meridional location of KQSF.In nearly 50 years,the Yunnan CW frequency has decreased and the meridional location of KQSF is slightly by west.The annual change has obviously negative correlation.When the CW frequency is more (less) than the normal,the KQSF location is more west(east) than the normal.The relationship is closer in the west side of the KQSF (the front of KQSF) than the east side of the KQSF (the back of KQSF).④The CW movement has closely relationship with KQSF movement.When the CW location is more west than the normal,the KQSF location is also more west than the normal;and vie versa.The CW intensity has positive correlation with the KQSF location.When alternating temperature (or temperature anomaly) is bigger(smaller),the KQSF location is more east(west) than the normal.关键词
