This exploratory research will focus on a set of experiments using the atmospheric component of the NCAR CCSM to test the behavior of the model using different parameterizations of deep convection. Annual integrations of the standard version of CCSM will be carried out, each run using one of the convective schemes: Zhang-McFarlane, Zhang-McFarlane + (includes physical triggers and closure modifications for convection), Arakawa-Schubert, Relaxed Arakawa-Schubert, and Prognostic Arakawa-Schubert.The work is important because it should provide a strong diagnostics underpinning to the CCSM project from a university based group engaged in dynamical diagnosis of observed climate variability. The results from this project will be useful in identifying the convection scheme that will be incorporated in the next version of the model, scheduled for early 2001.

这项探索性的研究将集中在一组实验中，使用NCAR CCSM的大气成分来测试模式的行为，使用不同的深对流参数化。每年将进行CCSM标准版本的积分，每次运行使用以下对流方案之一：Zhang-McFarlane，Zhang-McFarlane +（包括对流的物理触发和闭合修改），Arakawa-Schubert，Relaxed Arakawa-Schubert，《荒川预言》预告片Prognostic Arakawa这项工作很重要，因为它应该为CCSM项目提供一个强有力的诊断基础，该项目来自一个从事动态研究的大学团体。对观测到的气候变率的诊断。该项目的结果将有助于确定将纳入定于2001年初编制的下一版模式的对流方案。
