摘要/Abstract

摘要：

西北太平洋副热带高压是影响我国夏季气候的一个非常重要的环流系统,本文主要分析了其年代际尺度的变化。发现在1979/1980年前后,其强度和范围发生了一次明显的年代际尺度的变化。1980年代以来,副高明显偏强,范围向西向南显著扩展。副高的年代际变化也对我国东部地区的气候产生了显著的影响。主要表现在近20多年来长江中下游地区夏季降水显著增加,华南地区夏季气温显著偏高,以及西太平洋20oN以南台风活动相对偏弱而20oN 以北洋面台风活动相对增强。副高的年代际变化与冬、春季赤道太平洋海表温度及同期热带印度洋海温有密切联系。

Abstract:

Western North Pacific Subtropical High is a very important atmospheric circulation system influencing the summer climate over eastern China. Its interdecadal change is analyzed in this study. There is a significant decadal shift in about 1979/1980. Since 1980, the Western North Pacific Subtropical High has enlarged, intensified, and shifted southwestward. This change gives rise to an anti-cyclonic circulation anomaly over the region from the South China Sea to Western Pacific and thus causes wet anomalies over the Yangtze River valley. During the summers of 1980-1999, the precipitation is 63.9 mm above normal, while during 1958-1979 it is 27.3 mm below normal. The difference is significant at the 99% confidence level as a t - test shown. The southwestward expanding of the Western North Pacific Subtropical High also leads to a significant warming in the southern China, during the 1980-1999 the summer mean temperature is 0.37^oC warmer than that of the period 1958-1979. The strong warming is primarily due to the clearer skies associated with the stronger downward air motion as the Western North Pacific Subtropical High expanding to the west. It is also found that the relative percentage of tropical cyclones in the regions south of 20^oN has been decreasing since the 1980s, but that in the regions north of 20^oN has been increasing during the same period. The Western North Pacific Subtropical High responds significantly to sea surface temperature of the tropical eastern Pacific with a lag of one-two seasons and simultaneously to sea surface temperature of the tropical Indian Ocean. The changes in the sea surface temperatures are mainly responsible for the interdecadal variability of the Western North Pacific Subtropical High.

Key words: Western Pacific Subtropical High, interdecadal change, climate change
