Abstract
Based on the Ishii ocean climate database (1945 to 2010), the summer temperature were analyzed at the notable PN section of the Kuroshio in East China Sea (ECS) for the past 66 years, to discuss the inter-annual changes and variability of summer temperature with depth. The temperature values of average, largest and least are chosen, layer by layer with a 50m space, from the sea surface to 700m depth, to check out the inter-annual changes and variability. It can be found, that in the past 66 years, the temperature at the upper layers shallower than 300 m was significant warming, the warmer tendency was stronger at shallower layers; but the temperature tend to cold at the lower layers deeper than 500 m, the cooling tendency of the minimum values of temperature was more clearly and strong. The temperature difference between the upper layer and the lower layer was expanding during 1945 to 2010, this tendency become more obvious after year of 2000.
