简介:NCEP/NCAR每日的分析数据和中国每日的gridded降水数据被用来学习在aprupt干旱洪水之间的关系转移中间低的活动范围在2011的长江和intraseasonal摆动(ISO;3060天)在中间高度的纬度在东亚上的上面的对流层的南方的循环。到洪水的从干旱的突然的转变发生在早6月。复杂实验直角的功能的开始的二个恢复领域证明从低纬度的向北方繁殖的westerlies在中间迟了的5月在长江(MLRYR)的中间低的活动范围上从高纬度与向南方繁殖的westerlies收敛。预定这集中在早中间的6月对应于洪水时期。ISO索引显著地并且断然在MLRYR上与降雨被相关。在干燥阶段期间(在转变前),在MLRYR上的上面的对流层被气旋的流动描绘,在东方风,和集中。地区性的发行量被一列波浪火车在MLRYR上在湖贝加尔湖,在北中国上的反气旋,和气旋的东方上与气旋统治。在湿阶段期间,状况被颠倒。波浪火车的配置在干燥阶段期间赞成西的风骚乱的向南方的繁殖,当波浪火车的配置在MLRYR上在湿阶段期间赞成抽的效果和持续上升运动的发展和维护时。
