Coupled surface winds and ocean surface diurnal variability using WRF
Case study simulations of the coupled influences of diurnal sea surface temperature variations and wind stress curl and divergence are examined through the use of two sea surface temperature parameterizations in the Weather Research and Forecasting (WRF) model. First, an idealized 7-day simulation will consist of artificially modified SSTs in the central Atlantic with a consistent heating pattern from day to day. Using an idealized heating pattern in the SST field will help address the integrity of developing atmospheric gravity waves emanating from SST heating found in preliminary results. Second, a more realistic simulation for the same domain will be performed in which SSTs will be updated according to the skin sea surface temperature parameterization within WRF by Zheng and Beljaars (2005). This will help in identifying consistencies between coupled feedbacks on heating of the atmosphere, horizontal pressure gradients, and the possible self-limiting nature of surface winds and diurnal variability of the ocean.
