Diagnostics for near-surface wind convergence/divergence response to the Gulf Stream in a regional atmospheric model

Precipitation Response to the Gulf Stream in an Atmospheric GCM*

The precipitation response to sea surface temperature (SST) gradients associated with the Gulf Stream is investigated using an atmospheric general circulation model. Forced by observed SST, the model simulates a narrow band of precipitation, surface convergence, and evaporation that closely follows the Gulf Stream, much like satellite observations. Such a Gulf Stream rainband disappears in the ...

Atmospheric Response to the Gulf Stream: Seasonal Variations*

The atmospheric response to the Gulf Stream front in sea surface temperature is investigated using highresolution data from satellite observations and operational analysis and forecast. Two types of atmospheric response are observed with different seasonality and spatial distribution. In winter, surface wind convergence is strong over the Gulf Stream proper between Cape Hatteras and the Great B...

Evidence for a weakening of tropical surface wind extremes in response to atmospheric warming

Assessment of a Parametric Hurricane Surface Wind Model for Tropical Cyclones in the Gulf of Mexico

Tropical cyclones, which generate storm surges, wind waves, and flooding at landfall, are a major threat to human life and property in coastal regions throughout the world. The Unit‐ ed States, the northern Gulf of Mexico, and in particular the Louisiana Gulf coast, are very susceptible to the impacts of frequent tropical storms and hurricanes due to its tropical/ subtropical location and uniqu...

Air-sea interactions during the passage of a winter storm over the Gulf Stream: A three-dimensional coupled atmosphere-ocean model study

[1] A three-dimensional, regional coupled atmosphere-ocean model with full physics is developed to study air-sea interactions during winter storms off the U. S. east coast. Because of the scarcity of open ocean observations, models such as this offer valuable opportunities to investigate how oceanic forcing drives atmospheric circulation and vice versa. The study presented here considers condit...
