Abstract: The mechanism of the development and maintenance of the zonal circulation of the atmosphere is discussed from the point of view of vorticity transfer by atmospheric disturbances. Because the disturbances with vorticity ...

Abstract: In the first part of this paper, the partial differential equations governing the three-dimensional large-scale disturbances in a baroclinic zonal current are derived by applying a semi-Lagrangian coordinate system. These ...

Abstract: Atmospheric vortices are treated as masses of air with certain distributions of vorticity, with or without solid boundaries. It is shown that in the northern hemisphere the effect of the vorticity distribution in the ...

Abstract: In discussing wave motions along a strong jet of westerlies, we can no longer neglect the variation of west wind with latitude, and therefore must consider the possibility of having a phase velocity whose value is between ...

Abstract: The structure of squall-line type thunderstorms is investigated with special emphasis on the upshear sloping updraft which is often observed in these storms. To aid in the investigation, a new version of the convective ...

Abstract: The stationary wave components of the planetary-scale circulation are maintained by topographic forcing and by latent and sensible heat transfers and radiation. These waves have a potential vorticity balance mainly due to ...
