Abstract: seudomomentum and pseudoenergy are both measures of wave activity for disturbances in a fluid, relative to a notional background state. Together they give information on the propagation, growth, and decay of disturbances. ...

Abstract: A model of the linear stability of spiral-shaped potential vorticity (PV) filaments is constructed by using the Kolmogorov capacity as a time-independent characterization of their structure, assuming that the dynamics is ...

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: 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: AbstractA novel Lagrangian framework is developed to attribute monthly precipitation variability to physical processes. Precipitation variability is partitioned into a combination of five factors: airmass origin location, ...

Abstract: The humidity in the dry regions of the tropical and subtropical troposphere has a major impact on the ability of the atmosphere to radiate heat to space. The water vapor content in these regions is determined by their ...

Abstract: xtratropical cyclones are typically weaker and less frequent in summer as a result of differences in the background state flow and diabatic processes with respect to other seasons. Two extratropical cyclones were observed ...

Abstract: AbstractThe rate of humidity entrainment in the convective parameterization scheme in a general circulation model affects the simulation of convectively coupled waves. However, it is unclear whether this is caused directly ...

Abstract: A theoretical framework is developed for the evolution of baroclinic waves with latent heat release parameterized in terms of vertical velocity. Both wave?conditional instability of the second kind (CISK) and large-scale ...
