The climatic characteristics of explosive cyclogenesis in the northwest pacific 西北太平洋爆发性海洋气旋发生发展的气候学特征
2.
The relationship between cef and china summer rainfall and that between cef and tropical cyclone frequence ( tcf ) in the northwest pacific ( nwp ) are investigated . lt is found that the several branches of cross - equatorial flow have different interannual variability . periodicity and interdecadal variability . the five channels in the lower troposphere in the monsoon region of the eastern hemisphere have different relationships with china summer rainfall . the results also show that there are obvious relation between the interannual variatin of cef and tcf from july to october in the northwest pacific 确定了东半球季风区对流层高低层各支越赤道气流通道的位置，并探讨了越赤道气流与我国夏季降水和西北太平洋上热带气旋发生频数的年际变化之间的关系。结果表明：季风区夏季的几支越赤道气流具有不同的年际变率、周期以及年代际的变化特征。夏季季风区对流层低层的5支越赤道气流的强度与我国夏季降水呈不同的相关型。
