Atmospheric precipitation

The removal of arsenic from solution has relied mostly on precipitation and adsorption processes and it has been considered that arsenic is the oxidation state that leads to the most effective removal by precipitation since the simple metal arsenates generally have lower solubility than the arsenites, and also arsenate is more strongly adsorbed on certain substrates, but this is pH dependent.

从溶液中去除砷主要依赖沉淀和吸附过程，并且要考虑+5价砷是氧化态，会导致通过沉淀最有效去除砷，因为简单的金属砷酸盐比亚砷酸盐一般有更低的溶解度，并且砷酸盐在特定情况下有更强的吸附能力，但是这取决于 pH 值。

The first part is to assess whether RIEMS has ability to reproduce ten-years averaged mean climate in East Asia.The results demonstrate that RIEMS is capable to reproduce the patterns and seasonal cycle of temperature(mean temperature/maximal temperature/minimal temperature), precipitation, sea level pressure and arid index as well as the rain belt evolution.The simulated seasonal and monthly averaged temperature biases are generally in the range of 1-2℃,which are consistent with IPCC(200 1)report. Although model can reproduce the seasonal cycle and time evolution of precipitation, the simulated rain belt has northwards shift of 2-3 degree.

第一部分是检验RIEMS模式对东亚地区十年平均气候状况的模拟能力，结果表明，RIEMS模式能够较好地模拟出不同季节温度(包括平均温度、最高温度、最低温度)的空间分布和季节变化以及不同区域温度的年变化；无论是平均温度，还是最高温度、最低温度，模式模拟季平均和月平均温度与观测之间偏差大约一般在1-2℃，这与IPCC(2001)报告中报告的在区域尺度10〓-10〓KM，季平均温度偏差在1-2℃较为一致；模式能够较好地模拟降水的空间分布特征和季节变化以及不同区域平均降水的年变化，同时，也能够较好地模拟出雨带季节性的演变，但模拟的雨带位置较观测偏北，大约为2-3纬度；就季节而言，模式模拟最好的季节为冬季，较差的季节为夏季；模式基本上能够较好的模拟出不同季节平均海平面气压场的空间分布以及东亚地区的湿润和干旱分布规律的干旱指数的空间分布。

Pingchen for the new continental arid north temperate monsoon climate, four seasons, the winter-long, the average annual temperature of 6.0 ℃, frost-free period is 100-115 days,≥ 10 ℃ for the effective temperature of 2300 ℃, annual precipitation is 350-400 mm of precipitation More concentrated in six or seven, in August.

新平镇为大陆性北温带干旱季风气候，四季分明，冬季偏长，常年平均气温为6.0℃，无霜期为100—115天，≥10℃的有效积温为2300℃，年降水为350—400毫米，降水多集中在六、七、八月份。

Using the precipitation of the Indian summer monsoon onset process by the method of EOF expansion, the following conclusions can be found. The onset of the monsoon is mainly seen as the augmentation of precipitation and the rapid advance of monsoon rain belt with sudden change in the distribution of its space and time.
