Diabatic heating and cooling through cloud microphysical processes is a driver of uncertainty not only for the dynamics of the cloud and precipitation systems themselves, but also for the larger scale circulation. In this project, we will address this uncertainty for cold fronts in extratropical cyclones and the related high-impact weather (precipitation and gusts). Dedicated ICON simulations including systematic and stochastic perturba-tions of microphysical parameters will be analyzed with the help of statistical emulators.

通过云微物理过程的非绝热加热和冷却不仅是云和降水系统本身动力学的不确定性驱动因素，而且也是更大规模环流的不确定性驱动因素。在这个项目中，我们将解决温带气旋冷锋和相关高影响天气（降水和阵风）的这种不确定性。专用的 ICON 模拟，包括微物理参数的系统和随机扰动，将在统计模拟器的帮助下进行分析。
