中国近百年雨量与大气环流因子的关系
THE RELATIONSHIP BETWEEN THE CHINESE PRECIPITATION AND THE ATMOSPHERIC CIRCULATION FACTORS DURING THE RECENT 100 YEARS
-
摘要: 研究了近百年南方涛动年指数、北半球西风带大气环流W. C. E环流型年频数对中国大范围年降水量及旱涝的影响,探讨了大气环流因子影响的空间分布变化规律及影响的复杂性、非线性及南北环流不同配置多因子相互作用造成的综合影响特征,发现:(1)SOI、W. C. E环流因子对中国降雨的影响不是局地的,而是大范围普遍存在的,只不过对越靠近海洋的地方影响越显着;(2)并不是单个环流因子的变化就可完全解释清楚雨量的变化,多个环流因子复杂非线性相互作用,南北环流因子的不同配置结果对雨量产生的综合影响要重要得多。(3)环流因Abstract: That the annul Chinese precipitation is affected by the annul SOI,and the annual frequency of the W. E. C pattern of the westerly belt in the northern hemisphere during recent 100 years has been studied The composite features caused by the complex spatial allocation and evolution law of the atmospheric circulation,and the interaction of the different allocation factors of the northen and southern circulation has also been discussed
