中低纬度海表面温度日变化特征分析
Diurnal variabilities of sea surface temperature in the low-and mid-latitudes
摘要
Abstract
Aiming at the sea surface temperature diurnal amplitude (DSST),this study develops an empirical diagnosis model based on the observation data.Based on the 30a reanalysis data,the DSST data set with a horizontal resolution 0.3° × 0.3° is established.The temporal and spatial variation characteristics of DSST at the middle and low latitude are analyzed.The results show that the spatial variation is obvious,with a higher DSST value in the northern hemisphere and a lower DSST value in the southern hemisphere.The DSST has obvious seasonal variation.DSST value in the warm pool area of Western Pacific is higher in autumn,and in the eastern Pacific is high in four seasons.In the tropical Atlantic sea DSST value changes without obvious characteristic.Influenced by monsoon,the DSST value in the Arabian Sea and the Bay of Bengal is lower in summer compared to that in winter.The solar shortwave radiation and wind speed are the main reasons for the above characteristics.DSST anomaly over the past 30 years doesn't change obviously,while the interannual variation is obvious.The overall abnormal tendency of the interannual variation has downward trend,and the values have a certain correlation with Ni(n)o 3.4 index.关键词
