利用CSIRO共形-立方大气模式（CCAM）对1989-1998年亚洲夏季风的气候特征进行了研究。目前的研究的目的是验证模式的结果对以前的工作在这个问题上，以确定模式模拟亚洲夏季风的优势和劣势。模型的结果与现有的观测结果进行了比较，并提出了两个部分。在第一部分中，将夏季平均降水量、最高和最低温度以及风与观测资料进行了比较。第二部分是对季风爆发的验证。该模型捕捉的平均特征，如跨赤道流的低层风在印度洋和索马里海岸附近，降雨模式，发病指数，向北移动，活跃的休息和复兴时期。
A ten-year mean (1989–1998) climatology of the Asian summer monsoon is studied using the CSIRO Conformal-Cubic Atmospheric Model (CCAM) to downscale NCEP reanalyses. The aim of the current study is to validate the model results against previous work on this topic, in order to identify model strengths and weaknesses in simulating the Asian summer monsoon. The model results are compared with available observations and are presented in two parts. In the first part, the mean summer rainfall, maximum and minimum temperatures and winds are compared with the observations. The second part focuses on validation of the monsoon onset. The model captures the mean characteristics such as the cross-equatorial flow of low-level winds over the Indian Ocean and near the Somali coast, rainfall patterns, onset indices, northward movements, active-break and revival periods.
