本研究的目的是确定重要的物理过程，需要很好地代表在2007年7月15日发生在对流和地形诱导降水研究（COPS）的深对流云的模式模拟。2007年7月15日下午，一个孤立的深对流云发展起来，达到离地面12公里的高度。以前的研究表明，数值天气预报模型很难逼真地模拟这种特殊的云。在本研究中，它被发现，一个水库的湿空气的发展，提供必要的能量准备通过一个合适的触发器（收敛线的到来）释放。天气研究和预报（WRF）模式的一系列测试，以找到模拟的边界层和陆面规格的敏感性，以及这些必要的组合，以提供湿空气的水库。
This study aims to determine the important physical processes which need to be well represented in a model simulation of the deep convective cloud which occurred on the 15th July 2007 during the Convective and Orographically-induced Precipitation Study (COPS). During the afternoon of 15th July 2007, an isolated, deep convective cloud developed, reaching heights of 12 km above ground level. Previous studies have shown that numerical weather prediction models struggle to simulate realistically this particular cloud. In the present study, it is found that a reservoir of moist air developed, providing necessary energy ready to be released via a suitable trigger (the arrival of a convergence line). A series of tests of the Weather Research and Forecasting (WRF) model is employed to find the modelled sensitivities to boundary-layer and land-surface specification, and the combinations of these necessary to provide the reservoir of moist air.
