查询词典 rainfall distribution

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.

为了改进和发展Gregory积云参数化方案，(1)考虑了大尺度水汽辐合对积云对流的影响，即在混合卷入中加入有组织的卷入，让有组织的卷入存在于有大尺度水汽辐合的层次上，并且与大尺度水汽辐合直接成比例；(2)考虑了过冷水存在对饱和比湿的影响，调整了初始的质量通量，并且根据对大气加热加湿的诊断，调整了大气向下拖曳的强度；(3)根据我国降水多由层状云和嵌入其中的对流云混合产生的这一特点，对于过强对流过程进行抑制，在云顶加入有组织的卷出，同时加大向下拖曳的强度，减少蒸发以降低潜热的释放，抑制过强对流的发生。

Shule River project area is located in northwest China\'s Gansu province,Hexi Corridor,which is the largest agricultural crop production base of Gansu province and typically arid and semi-arid areas. There are characteristics such as scarce rainfall,the temporal and spatial distribution inequality,strong evaporation,fragile ecological environment,the limited quantity of surface water. Agriculture,the people\'s living and ecological environment are significantly dependent on the groundwater. Based on the collection and processing of regional hydrological and geological data and the groundwater monitoring data,using the numerical simulation,geostatistics theory and multi-objective evolutionary algorithm,this paper studied the monitoring and evaluation of groundwater resources from the three aspects: groundwater numerical simulation and prediction,groundwater spatial variability and distribution and optimization modeling and sloving of groundwater monitoring network. The main work and research lies:(1) Using Yumen-Tashi basin,Anxi-Dunhuang basin and Huahai basin as study area,this paper used modflow model to simulate groundwater flow of three areas.

本文在收集和整理项目区水文地质数据以及地下水监测数据的基础上，基于数值模拟、地统计学理论及多目标进化算法，从地下水数值模拟与预测、地下水空间变异与分布特征分析以及地下水监测网优化建模与求解三个方面展开了对项目区地下水资源监测与评价的研究，主要研究工作如下：(1)以项目区内的玉门-踏实盆地、安西-敦煌盆地和花海盆地为研究区域，在《河西走廊项目中期计划调整报告》规划条件下，基于modflow模型对地下水水流进行数值模拟，计算并生成了三个区域2007-2030年地下水埋深预测数据以及等值图。

The APW in summer is less than 25 mm which is the least limit value of monsoon areas.This means that Xinjiang is not affected by monsoon.The geographic distribution of APW is adverse with that of precipitation,videlicet,higherAPW values corresponding to lower precipitation values.With the effects of westerly winds,the APW mode presents as an uniform change within Xinjiang area and has a stable distribution.It is very different from Xinjiang rainfall mode which changes a lot spatially.As mentioned above,there is no obvious change during 1961～2000,this indicates that APW is not a dominant factor determining precipitation,it is the result of dynamic condition,water vapor convergence and other causes.

APW的地理分布与实际降水量分布相反，其最大区域却为降水量最小区，受西风带影响，新疆APW模态主要表现全疆一致变化，分布稳定，与降水模态分布差异性大有显著不同，且近40年来无显著变化趋势，表明决定新疆降水差异的根本原因不在于水汽的多少，而是由降水产生的动力条件、水汽辐合和其它因素差异决定的。

When picking information.those factors should be taken into consideration.(1)The kinds of rock and its distribution,(2)Geomorphy and slope class,(3)The landcover calss and grading,(4)The landuse class,(5)The townand city distribution and population density,(6)Hydrologic condition and rainfall.

信息采集时必须考虑的主导因子有：（1）岩石类型及空间分布；（2）地貌类型及坡度等级；（3）植被覆盖类型及等级；（4）土地利用类型；（5）区域城镇分布及人口密度；（6）水文条件、降雨量。

Since the Dirichlet distribution is the conjugate prior of the multinomial distribution, the beta distribution is the conjugate prior of the binomial distribution.

自的Dirichlet分布是共轭先验的多项分布， Beta分布是共轭先验的二项分布。

I was just taking her hand, to help her out of a car, and I knew it.

我只是握着她的手，扶她下车，但我知道这一切。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
