基于SODA3资料的西北太平洋海气边界层主要特征及相关性分析
Characteristics and correlation analysis of temperature and mixed layer depth in the western Pacific based on SODA3
摘要
Abstract
By using monthly and 5d data of SODA3.3.1 from 2011 to 2015,we analysis the characteristics of SST (sea surface temperature) and sub-surface temperature,MLD (mixed layer depth),wind stress and wind stress vorticity in the Westem Pacific,and the relationships between them are discussed with correlation method.The results show that there is a cold center near the equator;MLD decreases from south to north,and there are two maximum centers near the Kuroshio extension.Wind stress direction is north in winter and autumn with a higher value,while wind stress direction is west in spring and south in summer.SST has a negative correlation with MLD in most areas and shows a downward trends near equator.This trend is more obvious in La Nina years and not obvious in E1 Nino year.Sub surface temperature has a positive correlation with MLD to the north of 15°N and negatively correlated with MLD in the Kuroshio area.SST has a positive correlation with wind stress vorticity to the north of 15°N.The correlation index is high during Jan.to Mar.and Jul.to Oct.,and the correlation between sub-surface temperature and wind stess vortisity is irregular.关键词
