简介：当自台湾东面的菲律宾海流向日本的暖流的时间空间的可变性被mesoscale旋涡高度影响，代表它的季节的可变性特征要求足够地长期的观察减少无常。从1987～2010从水道学的观察估计的因地球自转而引起的速度数据和在在中央华东海的PN节的从1993～2008的舷侧ADCP速度数据被收集客观地看季节的可变性。从观察的两种类型，自台湾东面的菲律宾海流向日本的暖流水流的季节的气候学平均数在三个区域展出重要差别，这被发现，它在自台湾东面的菲律宾海流向日本的暖流当前的核心和它的二胁腹位于浅层不到300m，与在在秋天的核心的最弱的东北水流，在春天的正确胁腹上的最强壮的相反的水流，和在秋天的左胁腹上的最强壮的东北水流分别地。自台湾东面的菲律宾海流向日本的暖流水流的季节的变化也展出重要差别在上近海自台湾东面的菲律宾海流向日本的暖流的方面，与在春天和夏天的更大的变化当时在秋天和冬季的更小的变化。为到PN节的当前的平行，到intraseasonal可变性部件的季节的可变性部件的比率为对PN节垂直的水流是比那相对小的。进一步的分析显示在PN节的季节的可变性紧被连接到在上游、下游的当前的可变性。

简介：热带降雨测量的能力为测量降雨的使命(TRMM)卫星被在南部的中国在一个重降雨实验期间使用TMI-85.5GHz微波影像数据和降水数据检验。从有在有85.5GHz微波的TBB的一个小时的雨数量的分发的比较，大雨的中心与低TBB价值的一个区域相应，是清楚的。7gB分发的地点和形状类似于降水的，并且越大降雨率，越多降低TBB。统计分析证明在TBQ和雨率之间的相关系数否定、重要。特别，当雨率是超过7mm/h时，在TBQ和雨率之间的关联度是更重要的。TRMM/TMI-85.5G举办的结果表演测量对流大雨的极有能力。
