Abstract: A hydrostatic, primitive equation model is used to simulate an oceanic cyclone with idealized initial conditions. The model uses a pressure coordinate in the vertical with a grid spacing of 100 mb. In the horizontal a grid ...

Abstract: A two-layer primitive equation model with a parameterization for slantwise convection is used to study explosive cyclones. The parameterization includes a simple representation of the planetary boundary layer, as well as ...

Abstract: A three-layer primitive equation model with a representation of slantwise convection is used to study explosive marine cyclogenesis. A simple representation of boundary layer and shallow and deep cloud types is considered. ...

Abstract: The life cycle of an intense marine cyclone is documented in this paper. The departure of the moist dynamics from the dry baroclinic dynamics is explored from an energetics point of view. The contributions of various ...

Abstract: An initially axisymmetric hurricane was explicitly simulated using the high-resolution PSU?NCAR nonhydrostatic mesoscale model (MM5). Spiral potential vorticity (PV) bands that formed in the model were analyzed. It was ...

Abstract: A two-dimensional anelastic model is used to study the propagation of errors arising from the use of open lateral boundaries. Reference experiments were performed using very large horizontal domains. Other experiments were ...

Abstract: his study presents an information-theoretical score (ITS) with an emphasis on desirable and undesirable mutual information between a series of dichotomous forecast and observation. As ITS makes use of the same contingency ...

Abstract: Highly asymmetric structures in a landfalling hurricane can lead to the formation of heavy rains, wind gusts, and tornados at prefered locations relative to the center of the hurricane. In this study, the development of ...

Abstract: he role of asymmetric convection to the intensity change of a weak vortex is investigated with the aid of a ?dry? thermally forced model. Numerical experiments are conducted, starting with a weak vortex forced by a localized ...

Abstract: A three-dimensional anelastic model is used to perform simulations of explosive cyclones. The major goals are 1) to investigate the importance of horizontal resolution on the simulation of mesoscale features during explosive ...
