  • 简介:非洲或亚洲的居民夏天季风是一个地带地行星规模的系统,与盖住在过去的世纪(1901-2014)并且在最后三十年(1979-2014)期间的interdecadaltimescales上的非洲,南亚和东亚的大规模rainbelt。降水的一个最近的突然的变化发生在1990年代末。从那以后,Afro亚洲季风系统的全部rainbelt以一个协调方法向北进展了。在Huanghe-Huaihe河山谷和Sahel上的降水的一致增加与teleconnection模式由大西洋Multidecadal摆动(AMO)的温暖的阶段激动被联系。与轮流出现的气旋/反气旋,一列teleconnection波浪火车在上面的对流层被检测。沿着teleconnection路径,在诺思非洲的发行量异例的配置被与低级热低压力(集中)上层的反气旋(分叉)联合描绘,便于登上在Sahel的运动的开始和发展。在东亚,同样,acoupled发行量模式也在Huanghe-Huaihe河山谷使上升运动激动。在Sahel和Huanghe-Huaihe河山谷上的降水的同步增加能被归因于同现,上升的同相的变化打手势。在另一方面,AMO的温暖的阶段导致在诺思非洲和东亚的北部分的在上面的对流层的重要温暖。如此的温暖贡献增强热带在东方通过在入口区域(东亚)和出口区域(非洲)两个都增加南方的压力坡度的喷气。因此,在Sahel和Huanghe-Huaihe河山谷上的降水加强,由于ageostrophic第二等的房间。这研究的结果在非洲或亚洲的居民夏天季风为一个一致、整体的interdecadal变化提供证据。

  • 简介:600年的集成与Bergen气候模型和公民一起执行了的A为环境预言/公民中心集中因为大气的研究(NCEP/NCAR)分析数据被用来在东方亚洲夏天季风(EASM)和EASM降雨上调查强壮的热带暴烈的爆发的影响。模拟和NCEP/NCAR分析数据显示出一在强壮的爆发年里变弱EASM。模型模拟建议诺思和华南经历干旱,Yangtze-Huaihe河山谷在爆发年期间经历洪水。响应强壮的热带暴烈的爆发,在上面的对流层的南方的空气温度坡度被提高,它导致向南方的移动和东方亚洲副热带的西的喷气溪流(EASWJ)的增加。同时,陆地海在亚洲陆地团之间的热对比和西北太平洋被削弱。陆地海的EASWJ和减小的向南方的移动和增加所有贡献一变弱EASM和EASM降雨异例的热对比。

  • 简介:在为1971-的中国的使用的每日的NCEP/NCAR分析数据集和观察降雨数据2000时期,一个副热带的夏天季风索引被全部的空气列的南方的潮湿运输定义。副热带的夏天季风索引由在华南和诺思中国之间的南方的潮湿运输的差别定义的结果表演能被用来描述副热带的夏天季风的紧张。高(低)索引相应于强壮(弱)副热带的夏天季风。并且新索引与在长江的中间、更低的活动范围上的夏天降雨有关好。另外,从经由从北方中国的华南海和那的西方太平洋的潮湿运输的集中可能为在长江的中间、更低的活动范围上的反常地过多的夏天降雨负责。
