An outstanding problem in numerical modeling of atmospheric circulation is representation of cloudiness associated with vigorous convection. An associated problem is the interaction between cloud and radiation processes which often dictate the ambient environment at a place. The PI, Dr. Betts, has developed a novel formalism called the saturation point method which allows accurate representation of vigorous convection in numerical models. Dr. Betts now proposes to apply this method in observational and theoretical studies of atmospheric convection. He plans to actively participate in application of the method to data collected during the 1987 field phase of the "FIRE Project" (a U.S. regional experiment to study cloud.radiation interaction). His work could potentially lead to accurate development of numerical schemes to represent vigorous convection in global forecast models.

大气循环的数值建模中的一个杰出问题是代表与剧烈对流相关的浑浊。 一个相关的问题是云与辐射过程之间的相互作用通常决定一个地方的环境环境。 Betts博士，PI开发了一种称为饱和点方法的新型形式主义，该方法允许在数值模型中准确表示剧烈对流。 贝茨博士现在建议将这种方法应用于大气对流的观察和理论研究。 他计划在1987年“消防项目”（美国研究云的区域实验）期间积极参与将方法应用于收集的数据。 他的工作有可能导致数值方案的准确发展，以代表全球预测模型中的有力对流。
