Time-lapse video of the Intense Observation Period (IOP)16a case study

For the first time Large Eddy Simulations (LES) of Mediterranean convective systems, initialized with real observed conditions (AROME-WMED), over a large domain encompassing the Northwestern Mediterranean (900 million grid points) were carried out for IOP16a and IOP13<br /> <br /> Observing strategy: <br /> The time-lapse video for IOP16a highlights the realistic growing stage of the convective cells, from shallow cumuliform stage until regenerating deep cell trains within a low level convergence line本研究首次针对地中海对流系统开展大涡模拟（Large Eddy Simulations，LES），采用真实观测条件（AROME-WMED）进行初始化，模拟区域覆盖西北地中海全域，网格点数达9亿，相关模拟任务针对IOP16a与IOP13两个观测时段展开。 观测方案： 针对IOP16a的延时视频清晰展现了对流单体的真实演化阶段——从浅积云阶段，直至低层辐合线内再生的深厚对流单体群的发展全过程。
