简介：在用有不同积云parameterization计划和决定的AGCM的六集成的Madden-Julian摆动(MJO)被检验在MJOsimulation.Results上调查他们的影响建议MJO模拟能被分辨率和积云parameterization影响，尽管后者，它在模仿MJO和模仿的MJO的特征决定AGCM的基本能力，比前者更关键。模型分辨率能实质地在某些方面影响模仿的MJO。增加的分辨率不能实质地改进模仿的MJO，但是能显著地调制模仿的MJO的详细特性；同时，分辨率的影响依赖于积云parameterization，决定MJO的基本特征。在决定的变化不改变模仿的MJO的性质，但是相当自己调整模拟，它被积云parameterization计划抑制。Theretbre，垂直决定需要同时被增加。加热的diabatic的垂直侧面可以是为这些不同建模结果负责的一个关键因素。到大程度，它被使用的积云parameterization计划决定。

简介：第五产生的宾夕法尼亚州的University/NCARMesoscaleModelVersion3(MM5V3)被用来在1999年6月在长江盆上模仿极端重降雨事件。模型极端气候事件上的水平、垂直的决定的效果详细被调查。原则上，模型能描绘每月重的降水的空间分发。结果显示水平分辨率的增加能减少建模的大雨的偏爱并且相当在学习时期期间模仿每日的降水的变化。导致的一个更好的垂直决定显然与更小的偏爱改进降雨模拟，并且因此，更好解决重降雨事件。在水平、垂直的分辨率的Theincrease能生产重降雨事件的更好的预言。在不同水平、垂直的格子间距的情况中改变的不仅降雨模拟，而且另外的气象学的领域在模型以决定变化表明了多样的变化。在模仿的海平面气压的明显的改进源于水平分辨率的增加，但是模拟对垂直格子间距感觉迟钝。垂直分辨率的增加能在底层提高地面温度以及大气循环的模拟，当在中间、上面的层次的循环的模拟在改变分辨率上被发现是少得多依赖时。另外，积云parameterization计划显示出高敏感到水平分辨率。Differentconvective计划关于改变分辨率在降雨模拟展出了大差异。在Grell计划的对流降水的百分比与增加水平分辨率增加了。相反，Kain-Pritsch计划引起了对流降水的减少的比率总计相应于增加水平分辨率的降雨累积。

简介：降水和联系的云水疗院流星有大时间、空间的可变性，它使预报的精确量的降水困难。因此，精确降水的依赖和时间、空间的规模上的联系的云模拟成为一个重要问题。我们报导由把控制实验与实验作比较在这个问题上解决当模特儿的分析的云由起始的温度，水蒸汽，和云条件使不安。仅当不安实验和控制实验之间的root-mean-squared差别比标准差小，模拟被认为精确。分析可以建议精确降水和云模拟不能同时在两好时间、空间的规模上被获得，它限制预报的量的降水。水蒸汽集中的精确模拟能在每日的时间规模上导致精确降水和云模拟，但是它不能对降水和云模拟有益在上时时，时间由于云过程的优势可伸缩。
