Abstract: The usefulness of any simulation of atmospheric tracers using low-resolution winds relies on both the dominance of large spatial scales in the strain and time dependence that results in a cascade in tracer scales. Here, a ...

Abstract: Consideration of flows in which the rate of change of momentum is much smaller than the Coriolis force suggests that the advected quantity momentum may be approximated by its geostrophic value but that trajectories cannot ...

Abstract: From spectral analyses of the 1° terrain heights of Gates and Nelson (1975), the representation of the earth topography by truncated series of spherical harmonics is obtained. Rhomboidal and triangular truncations at various ...

Abstract: Advection in weather systems results in filamentary and spiral structures in tracers, whose complexity increases as stirring progresses. Characterizations of fine-scale structures in chemical tracers, which are typically ...

Abstract: The response of a barotropic model, linearized about a climatological 300-mb December?February time-mean flow to localized forcing, is considered. In order to aid the design of the experiments and interpretation of the ...

Abstract: The global response to tropical heating is studied by performing a time integration of a 15-level primitive equation model, starting with a basic flow maintained by a constant forcing. The direct, quasi-steady response to ...

Abstract: his manuscript revisits a study of eddy?mean flow interactions in an idealized model of a western boundary current extension jet using properties of the horizontal velocity correlation tensor to diagnose characteristics ...

Abstract: he impact of El Niño?Southern Oscillation (ENSO) on atmospheric Kelvin waves and associated tropical convection is investigated using the ECMWF Re-Analysis, NOAA outgoing longwave radiation (OLR), and the analysis technique ...

Abstract: Atmospheric general circulation model experiments have been performed to investigate how the significant zonal asymmetry in the Southern Hemisphere (SH) winter storm track is forced by sea surface temperature (SST) and ...

Abstract: It is shown how to estimate the directions and relative magnitudes of Q-vectors from a map of isobars and isotherms. The divergence of this vector field represents the forcing function in the quasi-geostrophic omega-equation. ...
