简介：根据在2009的冬季和夏天的CTD数据和当模特儿的结果，在西方的华东海架区域的水群众的季节的特征用一个簇分析方法被分析。结果证明在学习区域的水群众的分布和温度咸度特征具有不同季节的差别。在西方的华东海架区域，在冬季期间有三水群众，即，沿海的水(CCW)，台湾温暖的当前的表面水(TWCSW)和混合的黄海浇的大陆人(YSMW)，而是四在夏天期间，即，CCW，TWCSW，台湾温暖的当前的深水(TWCDW)和YSMW。都所有，CCW，TWCSW和TWCDW中是主导的水群众。CCW，首先由低咸度描绘了，在冬季有更低的温度，更高的咸度和更小的空间程度比在里面夏天。TWCSW在比在冬季的夏天更温暖、更新鲜、更小，并且它在冬季期间从台湾海峡水台湾，中国和更少向东北主要从自台湾东面的菲律宾海流向日本的暖流表面水(KSW)发源，但是它在夏天期间由海峡水和KSW组成。TWCDW被低温度和高咸度描绘，并且台湾向东北在自台湾东面的菲律宾海流向日本的暖流表面下的水里完全发源。
