简介：水样品从2002年8月在四巡航以后在Changjiang河口的沿海的区域被收集到2003年5月。溶解的无机的砷(DIA)的季节变异分布被分析。结果证明DIA的分布被陆上的输入和自台湾东面的菲律宾海流向日本的暖流表面下的水(KSSW)的侵入主要影响。全部的溶解的无机的砷(TDIA)的Theconcentration从冬季连续地减少了到夏天，当它在秋天增加了时。TDIA的分布与咸度显示出一些关系并且推迟了微粒物质(SPM)。在DIA种形成之间的关系(包括亚砷酸盐[作为(Ⅲ)]并且砷酸盐[作为(Ⅴ)])，生物活动和磷酸盐的可获得性为巡航2002年8月在学习区域被调查。比率作为(Ⅲ)/TDIAs与磷酸盐集中的减少增加了。在底部水里，同样(Ⅲ)/TDIAs比率与增加N/P减少了。TDIA的集中减少了在有害海藻的花蕾(HAB)的出现以后的28.7%approximately因为由水藻的砷酸盐的举起。进一步的学习在有害海藻的花蕾的出现期间在他们的垂直或水平的侧面和举起机制关于砷来源/水池关系被需要。

简介：关联分析被用来在中国和东方亚洲夏天季风(EASM)上学习在春天土壤潮湿之间的关系。EASM在西南中国和黄河的大拐弯区域上与春天土壤潮湿有强壮的积极关联，这被显示出。一个标准土壤潮湿索引(SMI)用二个区域的观察土壤潮湿被定义。结果证明SMI与EASM有强壮的关联。年强壮(弱)SMI与被联系更强壮(更弱)夏天季风循环。在强壮的SMI的年里，向西和平的副热带的高度在位置向北方多并且在紧张更弱；westerlies地区也是到北方的更多。所有这些让EASM循环向北方移动并且引起降雨带重定位到诺思中国和东北中国。SMI能在东方中国上反映夏天降雨异例的变化。在强壮的SMI的年里，降雨带主要在China.However的northem部分上被定位，在弱年期间，夏天降雨带大部分被定位在上中间--并且更低--长江的活动范围。另外，SMI有伪4-6年和伪的明显的摆动2年。而且，否定SMI比积极SMI更好预言EASM。

简介：为2007的模型模拟和水文学分析数据被使用在沿海的东亚上在hydrometeor形成上调查远程的荒芜的灰尘运输的影响。结果从香港和上海被分析，它是东亚的二个代表性的沿海的城市。远程的荒芜的灰尘运输主要在沿海的东亚上影响春天和夏天云和猛冲。在春天，云和猛冲主要来自大规模冷凝作用并且主要被灰尘从Gobi，撒哈拉沙漠，和一种羚羊沙漠影响。这些荒芜的灰尘能参予降水在以内并且在云下面。在更低的纬度，灰尘粒子主要充当水原子核。在更高的纬度，他们充当水原子核和冰原子核。大规模云和猛冲上的Gobi，撒哈拉沙漠，和一种羚羊灰尘的效果在更高的纬度变得更强壮。在夏天，在沿海的东亚上的云和猛冲主要来自传送对流并且主要被灰尘从Taklamakan影响，阿拉伯，并且Karakum-Kavir沙漠。大多数Taklamakan灰尘粒子能作为冰原子核在对流的云以内参予降水，当阿拉伯时，Karakum-Kavir灰尘粒子在云下面在降水仅仅作为水原子核参与。对流的云和猛冲上的Taklamakan灰尘的效果在更低的纬度变得更强壮。所有荒芜的灰尘，那从Gobi和Taklamakan沙漠有相对最大的影响。Gobi灰尘由在更高的纬度影响泉水云在沿海的东亚影响气候变化。
