Abstract: The surface wind field in a developing tropical cyclone (Agnes, 1972) was analyzed over a 1660 km radius for four days using conventional surface data, as the storm evolved from a disorganized depression to a hurricane. ...

Abstract: A simple framework is presented for adjusting the normal wind components in a polygon of data points which produces a vanishing vertical integral of horizontal divergence, allows correct calculation of flux and advective ...

Abstract: The interaction of Hurricane Elena (1985) with a baroclinic wave was reexamined using both potential vorticity (PV) and a formulation for Eliassen-Palm fluxes in cylindrical coordinates. The hurricane began to deepen rapidly ...

Abstract: The Eliassen balanced vortex model assumes gradient balance of the azimuthal mean flow. This assumption was tested by calculating mean and eddy terms in the radial momentum equation in the synoptic-scale environments of ...

Abstract: A significant sign reversal in the meridional potential vorticity gradient was found during the summer of 1991 on the 310-K isentropic surface (near 700 mb) over the Caribbean Sea. The Charney?Stern necessary condition for ...

Abstract: The genesis of Hurricane Hernan (1996) in the eastern Pacific was investigated using gridded analyses from the European Centre for Medium-Range Weather Forecasts and gridded outgoing longwave radiation. Hernan developed ...

Abstract: A stationary mountain wave, embedded in southwesterly flow over Mont Blanc in the Alps, was observed simultaneously by three research aircraft and three types of remote sensing: GPS dropsondes, airborne light detecting and ...
