降水分布

Based on complete analysis of data about mountain torrent disaster and precipitation in Inner Mongolia in recent 50 years,the spatiotemporal distribution characteristic,periodic change regularity and influence factors for mountain torrent disaster in Inner Mongolia were obtained.

在全面系统地统计分析近50年的内蒙古山洪灾害和降水资料的基础上，得出了内蒙古山洪灾害发生的时空分布特征周期变化规律和影响因子。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.

Moreover, in a small area, due to changes in altitude, rainfall distribution was not uniform.

不仅云云，在小范围内，由于海拔高度的变化，降水的分布也不匀称。

They are used in a wide range of applications, where there are differences in wind speed and direction, levels of local turbulence, rate and droplet size, distribution of rainfall and surface water flow from the surrounding structure.

它们被用来在广泛的应用，在有风的速度和方向的差异，局部动荡，水平，速度和雾滴大小，降水和地表结构，从周围的水流量分布。

Rainfall is a key climate factors, the space-time distribution of rainfall and directly affect agriculture production, ecological environment, the inhabitants and the development of social economy.

降水是一个主要气候因子，降水量的多少和时空分布，直接影响到农牧业生产、生态环境、居民生产生活和社会经济的发展。

The characteristics of the general circulation in winter,spring and summer, East Asian monsoon, summer rainfall and the distribution of drought/flood in China are discussed.

我国夏季降水和旱涝有明显差异的四种不同分布型可能与冬季所处 ENSO循环的不同阶段以及大气环流和东亚季风对它的不同响应有关。

But due to the complex of natural condition, the un-uniform distribution of rainfall, and the change to ecoenvironment resulted from long-term activities of human being, drought disaster always happens in the region.

然而，由于地形地貌、气候条件的复杂多变，降水的时空分布不均，以及人类的长期干预造成的生态环境的改变，致使该区连年干旱。

Second, it represents a period when patterns of rainfall could have been very different.

其次，在某一时期降水的分布和形式也会不同。

The result shows that the effect of the SIA based on the DEM of 4 km resolution is preferable.

结果表明：逐步插值法得到的高分辨率降水空间分布效果较好，计算的精度较高。

The RegCM2 model is capable of well simulating regional distribution of anomalous precipitation in years of wetter and dryer summer that disclose the effects of different dynamic and thermal structures of the preceding spring, the results of which will provide scientific basis to some extent for short-term climate prediction in Northwest China.

采用RegCM2能较好模拟西北地区夏季干、湿年异常降水的区域性分布，并揭示出西北地区夏季干、湿的前期春季动力、热力结构差异的影响效应，为西北地区短期气候预测提供一定的科学依据。
