Abstract: The linear theory for hydrostatic nonrotating flow over an axisymmetric hill is redone in isosteric (i.e., constant specific volume) coordinates, thus allowing the lower boundary condition(LBC) to be exactly satisfied. ...

Abstract: To test the idea that observed oscillations in severe downslope winds are due to Kelvin?Helmholtz instability, the eigenvalues for the Taylor?Goldstein equation are found for a family of shear flows arising from local ...

Abstract: Linear hydrostatic 3D mountain wave theory is extended to include a thin frictional boundary layer (BL), parameterized using two characteristic relaxation times for wind adjustment. The character of the BL is described ...

Abstract: The first aircraft observations of the bora in Yugoslavia were accomplished during the ALPEX project in 1982. Data from all five ALPEX bora flights have been analyzed in a comparative study of bora structure. Although the ...

Abstract: During the ERICA project in 1989, ice crystals were collected from the tops bf two winter storms and one broad cirrus cloud. Deuterium concentration in the storm ice samples, together with a model of isotope fractionation, ...

Abstract: A hurricane beta-drift law is derived by applying dimensional analysis to the numerical simulations of Chan and Williams. The beta-drift speed and direction are given as simple functions of hurricane strength, radius, and ...

Abstract: A survey of existing synoptic data from the vicinity of major mountain ranges indicates two common aspects of orographic influence on the atmosphere?a hydrostatically generated pressure difference across the mountains and ...

Abstract: A theory of lee cyclogenesis is proposed, based on a linearized model of baroclinic wave generation by mountains in the presence of a background shear. The theory predicts that lee cyclogenesis will occur when the criterion ...

Abstract: Recent observations and numerical experiments indicate that during severe downslope windstorms, a large region of slow turbulent air develops in the middle and upper troposphere while strong winds plunge underneath. A ...
