The Response of an Axisymmetric Model Tropical Cyclone to Local Variations of Sea Surface Temperature
Publisher: American Meteorological Society
Abstract: An axisymmetric, multilayer, numerical tropical cyclone model with a well-resolved planetary boundary layer is used to test the response of local, instantaneous changes of sea surface temperature (SST). One experiment shows ...
Deep Ocean Response to Hurricanes as Revealed by an Ocean Model with Free Surface. Part I: Axisymmetric Case
Publisher: American Meteorological Society
Abstract: An axisymmetric, hydrostatic ocean model containing a rigid bottom and a free surface is constructed to study the barotropic and baroclinic response in the upper and deep ocean to a wind stress corresponding to a stationary ...
Numerical Simulation of the Influence of Sea Surface Temperature on Translating Tropical Cyclones
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical model with a domain of 3000 km?3000 km and horizontal resolution of 60 km is used to study the influence of sea surface temperature (SST) on the behavior of tropical cyclones translating with ...
Numerical Simulations of the Ocean's Nonlinear, Baroclinic Response to Translating hurricanes
Publisher: American Meteorological Society
Abstract: An asymmetric nonlinear ocean model is employed to investigate the oceanic response to moving hurricanes. A turbulent kinetic energy budget is used to parameterize the stress-induced vertical mixing. The results show that ...
Impact of Assimilating SSM/I Rainfall Rates on Numerical Prediction of Winter Cyclones
Publisher: American Meteorological Society
Abstract: A series of observing system simulation experiments (OSSE) and real data assimilation experiments were conducted to assess the impact of assimilating Special Sensor Microwave/Imager (SSM/I)-estimated rainfall rates on ...
Impacts of SSM/I Retrieved Rainfall Rates on Numerical Prediction of a Tropical Cyclone
Publisher: American Meteorological Society
Abstract: Special Sensor Microwave/Imager (SSM/I) retrieved rainfall rates were assimilated into a limited-area numerical prediction model in an attempt to improve the initial analysis and forecast of a tropical cyclone. Typhoon Flo ...
Free Surface Effects on the Near-Inertial Ocean Current Response to a Hurricane: A Revisit
Publisher: American Meteorological Society
Abstract: Free surface effects induced by an idealized hurricane based on observed air?sea variables in Hurricane Frederic are revisited to examine the barotropic and baroclinic response. Over five inertial periods comparisons between ...
Variational Analysis and the Slow Manifold
Publisher: American Meteorological Society
Abstract: The principles of variational analysis are reviewed in a symbolic manner, with emphasis on the error introduced by a failure to use an exact constraint. A technique to approximate a nonlinear exact constraint is suggested, ...
The Mutual Response of the Tropical Cyclone and the Ocean
Publisher: American Meteorological Society
Abstract: An axisymmetric hurricane model and an axisymmetric ocean model are integrated simultaneously for 24 h to investigate the mutual response of the two systems. The feedbacks between the hurricane and the ocean are negative. ...
