The evolution of tropical anvil clouds from their origin in deep convective cores to their slow decay determines the climatic effects of clouds in tropical convective regions. Despite the relevance of anvil clouds for climate and responses of clouds to global warming, processes dominating their evolution are not well understood. Currently available observational data reveal instantaneous snapshots of anvil cloud properties, but cannot provide a process‐based perspective on anvil evolution. We therefore conduct simulations with the high resolution version of the exascale earth system model in which we track mesoscale convective systems over the tropical Western Pacific and compute trajectories that follow air parcels detrained from peaks of convective activity. With this approach we gain new insight into the anvil cloud evolution both in present day and future climate.

拉格朗日对当前和未来气候中热带砧云生命周期的看法

热带砧云从其对流核心的起源到其缓慢衰减的演变决定了热带对流地区云的气候效应。尽管砧云对气候和云对全球变暖的响应具有重要意义，但主导其演化的过程仍未得到很好的理解。当前可用的观测数据可显示砧木云特性的瞬时快照，但无法提供基于过程的砧木演化观点。因此，我们使用高分辨率版本的百亿亿地球系统进行了模拟，在该模型中，我们跟踪了热带西太平洋上的中尺度对流系统，并计算了从对流活动高峰后降落的空气包裹的轨迹。
