摘要

利用1951-2014年NCEP/NCAR逐月、逐日再分析资料，1979-2014年CMAP降水资料对比分析了夏季各关键区大气热源及大气热源差值的变化特征，利用合成分析等方法探讨了关键区热力转换早晚对东亚副热带季风建立的影响，以及关键区热力差异大小对季风强弱的影响。结果表明，东亚与西太平洋热力转换早（晚）时，副热带季风建立时间早（晚），撤退时间晚（早），副热带季风持续时间长（短），热带夏季风爆发时间偏晚（早）。副热带季风建立的早晚与东亚和西太平洋热力转换的早晚在时间上较为一致。热带夏季风的爆发对副热带夏季风强度的增加有促进作用。高原的热力作用对东亚副热带季风的影响大于对热带季风的影响。海陆热力差值大（小）时，副热带高压脊线位置较常年偏南（北），东亚副热带地区表现为偏南（北）风距平，在低纬南海地区为偏西（东）风距平，高原及东亚大陆地区的上升运动较平均状态偏强（弱），西太平洋大部分地区的上升运动较平均状态偏弱（强）。且热力差值大时，南下的西北风与来自西太平洋的偏南风在30°N左右的副热带地区相汇，有利于此地区的降水的形成。包含高原的东亚与西太平洋热力差值大小比不包含高原的东亚与西太平洋热力差值大小对高度场、风场、垂直速度场的影响均更大。夏季热力差值大小对我国温度与降水的分布均有影响。

Abstract

By using NCEP/NCAR monthly and daily reanalysis data from 1951 to 2014 and the data of Climate Prediction Center Merged Analysis of Precipitation(CMAP) from 1979 to 2014, the thermal contrast over the key regions and the thermal differences over these areas in summer were analyzed, using synthetic analysis to discuss the impact of thermal conversion over the key regions on the onset of the East Asian subtropical monsoon, and the impact of thermal difference on the intensity of the East Asian subtropical monsoon. The conclusions were summarized as follows:When the time of thermal conversion between East Asian and Western Pacific Ocean is early(late), the onset time of East Asian subtropical monsoon is early(late), the retreat time of the East Asian subtropical monsoon is late(early), the duration of East Asian subtropical monsoon is long(short), and the onset time of tropical monsoon is late(early). The onset time of East Asian subtropical monsoon and the time of thermal conversion between East Asian and Western Pacific Ocean are consistent. And the onset of the tropical monsoon can promote the intensity of the East Asian subtropical monsoon. The thermal effect of the Qinghai-Tibetan Plateau has more impacts on East Asian subtropical monsoon than tropical monsoon. When the thermal difference between continent and ocean is bigger(smaller), the position of the subtropical ridge is southward(northward), the wind is southern(northern) anomaly at the East Asian subtropical region, the wind is westerly(easterly) anomaly at low latitude, the ascending motion at the Qinghai-Tibetan Plateau and the East Asian continent is stronger(weaker) than average state, the ascending motion at the Western Pacific Ocean is weaker(stronger) than average state. Moreover, when the thermal difference is bigger, the northwest wind from north area and the south wind from Western Pacific Ocean meet at the subtropical areas about 30°N have positive effect on the precipitation in this area. The thermal difference between East Asian including the Qinghai-Tibetan Plateau and the Western Pacific Ocean has more influence on height field, wind field and vertical velocity field than the thermal difference between East Asian excluding the Qinghai-Tibetan Plateau and the Western Pacific Ocean. The thermal difference in summer has influence on the distribution of temperature and precipitation in China.
