Basic points
Physical processes on scales order 1 km-100 km are fundamental to the diurnal cycle of convection.
Diurnal cycle and the organization of convection on mesoscales cannot be legitimately separated.
Mesoscale processes are not resolved in GCMs, not resolved or distorted in NWP models and RMMs (the scale-separation issue).
Mesoscale processes measured by the NAME Tier 1 observing facilities are represented explicitly by cloud-system-resolving models (CSRMs) over a similar dynamic range (1 km – 100’s km).
Gives prospect for understanding the diurnal cycle and the large-scale role of organized convection in complex coastal terrain and addressing convective parameterization aspects.
