降水

According to the analysing of groundwater recharge ,runoff,draining of groundwater and dynamics of springhead and so on,the authors have considered that the main causes of Baiquan springhead cutoff are the decrease in atmospheric water and artificial overexploitation groundwater.

文章从地下水的补给、迳流、排泄及泉水的动态等方面分析了百泉泉水断流的主要原因是大气降水的减少和人工过量开采地下水。

Mg/Sr ratio change is in accord with Mg/Ca of stalagmite record in Chongqing,which mainly affected by Mg~(2+) content change and it can be used as an proxy of past rainfall not temperature.

6重庆地区石笋中Mg/Sr与Mg/Ca比值变化一致，主要受Mg~(2+)变化的影响，可以作为古降水指标，而不能反映温度的变化。

It was a typical South China quasi-stationary precipitation which was associated with the stationary front, low-level wind shear and low-level jet.

这是建立在静止锋、低空切变线和低空急流等系统基础上的一次典型的华南准静止锋降水。

Based on NCEP and other observational datasets, a severe heavy rainfall process occurred in the south of china during June 18-19,1998 was investigated. The first diagnostic analyses show that the strong rainfall are produced by vortex, shear line and upper and lower jets, stationary front. The condition of high energy, saturation, potential instability is propitious to the form and maintenance of this rainfall.

采用NCEP全球谱模式和常规观测资料对98年6月18～19日华南暴雨的影响系统及其可能机制进行了初步诊断分析，发现这次强降水过程是受低槽、低涡、切变线、高、低空急流和地面静止锋共同影响造成的，该地区维持高能、饱和、潜在不稳定的环境，有利于暴雨的产生。

The vast majority belong to the temperate steppe and desert climate, strong continental precipitation inequality in the north of up to 300 mm, while the desert is less than 100 mm in mountainous areas can be up to 1600 millimeters.

绝大部分属温带草原和沙漠气候，大陆性强，降水不均，北部可达300毫米，而荒漠地带则不足100毫米，山区可多达1600毫米。

Shrub and subshrub FTs showed larger responses in dry years, whereas C3 and C4 annuals showed larger responses in wet years. Therefore, responses of desert ecosystems to a future elevated CO2 would be markedly influenced by precipitation patterns.

因此，无论是生态系统水平还是植物功能型水平，荒漠生态系统对未来大气CO2浓度升高的响应都将受降水格局的显著影响。

Interannual variation of subtropic high is the main cause of interannual variation of the rainfall in May over North China.
