aleutian low中文什么意思
阿留申低压区
例句与用法
- The different distributions of surface level pressure , wind ( 10 meter ) and surface air temperature before and after the regime shift indicate that the increase of aleutian low , position change of its core , and the change of wind field in accordance , especially during the winter months , are the major dynamic reasons for the significant reduction of ice extent in bering sea
结果表明: 20世纪70年代后期,海冰范围在白令海存在显著的均值突变现象,而楚科奇海在对应阶段则表现为更明显的变频现象;在突变点前后两个时段里,阿留申低压中心低压加强、核心位置偏移以及对应风场分布的变化是导致白令海海冰范围明显缩小的主要动力原因。 - On base of results above , composite model of ssta in pacific and circulation anomaly are constructed for analysis their evolution . during mature phase of el nino usually in winter , positive ssta dominates in tropical eastern ocean and negative ssta dominates in west wind drift district in mid - latitude ocean , correspondingly the pna index of 500 hpa geopotential height is positive which means the aleutian low gets strong , and the situation is somewhat inversely during la nina phase of ssta
合成位相反映了太平洋ssta演变特征,以及相对应的大气环流异常特征:当西风漂流区处于暖态而热带中东太平洋海温偏低时,合成大气模型当中阿留申低压减弱, 500hpapna指数为负异常;当西风漂流区处于冷态,热带中东太平洋处于暖态( elnino峰值?成熟期ssta典型分布) ,合成大气模型中阿留申低压加强, 500hpapna指数为正异常。
百科释义
