The Effect of Convective Parameterizations on the Dynamics of General Circulation Models

本探索性研究将侧重于利用NCAR CCSM的大气分量进行一组实验，以使用不同的深对流参数化来测试模式的行为。CCSM标准版本将进行年度整合，每次运行使用一种对流方案：Zhang-McFarlane， Zhang-McFarlane +（包括对流的物理触发和关闭修改），Arakawa-Schubert，放松Arakawa-Schubert和Prognostic Arakawa-Schubert。这项工作很重要，因为它应该为一个从事观测到的气候变率动态诊断的大学小组的CCSM项目提供强有力的诊断基础。该项目的研究结果将有助于确定对流模式，该模式将于2001年初发布。

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.
