Mixed Layer Mesoscales for OGCMs: Model development and assessment with T/P, WOCE and Drifter data
OGCMs T/P WOCE Drifter data
2011/9/8
In this paper we present a model for mixed layer (ML) mesoscale fluxes of an arbitrary tracer in terms of the resolved fields (mean tracer and mean velocity). The treatment of an arbitrary tracer, rat...
The potential influence of Asian and African mineral dust on ice, mixed-phase and liquid water clouds
