Fatima: Fog and turbulence interactions in the marine atmosphere
Abstract
Funds are provided to conduct research to advance our fundamental knowledge, prediction and detection capabilities pertinent to fog. The project will focus on Marine Sea Fog that forms over shallow seas and shelves as well as on coastal Ice Fog. Theoretical analysis, detailed process studies, novel high-resolution numerical simulations, extensive field measurements and predictive modeling in collaboration with practitioners will be included. The research objectives are to: (i) deploy leading-edge instrumentation and novel measurements techniques in field campaigns to probe from synoptic to microphysical scales, including the capture of (smallest) scales of atmospheric turbulence where momentum, temperature and moisture fluctuations dissipate and, together with physical and chemical properties of aerosols, control droplet growth; (ii) conduct theoretical and numerical analyses that push the frontiers of multi-phase turbulence, especially nonlinear interactions between fog droplets and turbulence; (iii) elicit earth-surface processes that dictate fog genesis and cause vivid differences between fog and low-level clouds; (iv) identify deficiencies of fog microphysical parameterizations in NWP models and implement improvements; and (v) understand and model fog and turbulence impacts on optical propagation.
