全球云分辨率模式(CRM)被用于一颗水行星的气候敏感性测试，这是第一次尝试在没有积云参数化的情况下评估气候敏感性。对控制试验和全球海温增温2K的试验结果进行了检验。在海温变暖的模拟中，显著的特征包括更宽的活跃对流区域，较弱的哈德利环流，副热带地区的对流层中层增湿，以及温带地区的更多云层。与使用积云参数化的更传统模式的结果相比，来自短波辐射的负反馈降低了气候敏感性参数。
A global Cloud Resolving Model (CRM) is used in a climate sensitivity test for an aqua planet in this first attempt to evaluate climate sensitivity without cumulus parameterizations. Results from a control experiment and an experiment with global sea surface temperature (SST) warmer by 2 K are examined. Notable features in the simulation with warmer SST include a wider region of active convection, a weaker Hadley circulation, mid‐tropospheric moistening in the subtropics, and more clouds in the extratropics. Negative feedback from short‐wave radiation reduces the climate sensitivity parameter compared to a result in a more conventional model with a cumulus parameterization.
