摘要利用1979-2007年全球候网格降水和全球850 hPa高度场资料,在候尺度上识别了全球季风槽和全球大气作用中心。全球季风槽由行星尺度季风槽和半岛尺度季风槽组成。热带辐合带(ITCZ)是受太阳辐射季节变化影响而形成的行星尺度季风槽,活跃于热带北太平洋、热带北大西洋和热带南印度洋。半岛尺度季风槽起源于区域性海陆地形,并随季节海陆表面温度和降水的差异而变化。在北半球夏季,亚洲-西北太平洋(NWP)地区分布着5个半岛尺度槽和1个行星尺度槽。总共有22个槽,9个季风槽和19个ACA在对流层低层被确定。相关的ACAS可能有助于构建区域季风和环流指数。
Abstract Using two datasets of global pentad grid precipitation and global 850 hPa geopotential height during 1979-2007, this study identified global monsoon troughs and global atmospheric centers of action (ACAs) on a pentad scale. The global monsoon troughs consist of planetary-scale monsoon troughs and peninsula-scale monsoon troughs. Forced by seasonal variations in solar radiation, the inter-tropical convergence zones (ITCZs) represent the planetary-scale monsoon troughs, which are active and shift over the tropical North Pacific, the tropical North Atlantic, and the tropical South Indian oceans. The peninsula-scale monsoon troughs are originated from regional land-sea topography and varied with contrasts in seasonal land-sea surface temperatures and precipitation. During the boreal summer, five peninsula-scale troughs and one planetary-scale trough are distributed in the Asia-Northwest Pacific (NWP) region. In total, 22 troughs, nine monsoon troughs, and 19 ACAs in the lower troposphere were identified. Relevant ACAs may be useful in constructing regional monsoon and circulation indices.
