Cloudy Puddle

Cloudy Skies

Standard Gaussian-type statistics are not really adequate to describe atmospheric variability; this traditional approach implicitly dismisses fluctuations as "noise" of use only in computing a standard deviation which, together with the mean, presumably varies so little in space and time that one can meaningfully speak of "climatological" values. In geophysics, unfortunately, this approach ofte...

A cloudy Vlasov solution

We propose to integrate the Vlasov-Poisson equations giving the evolution of a dynam-ical system in phase-space using a continuous set of local basis functions. In practice, the method decomposes the density in phase-space into small smooth units having compact support. We call these small units " clouds " and choose them to be Gaussians of elliptical support. Fortunately, the evolution of thes...

TOMS cloudy ozone anomaly

This study investigates anomalous ozone distributions over cloudy areas in Nimbus-7 (N7) and Earth-Probe (EP) TOMS version-7 data and analyzes the causes for ozone anomaly formation. A 5 •-longitude by 5 •-latitude region is defined to contain a Positive Ozone Anomaly (POA) or Negative Ozone Anomaly (NOA) if the correlation coefficient 5 between total ozone and reflectivity is ≥0.5 or ≤−0.5. Th...

Waves in a Cloudy Vortex

This paper derives a system of equations that approximately govern small-amplitude perturbations in a nonprecipitating cloudy vortex. The cloud coverage can be partial or complete. The model is used to examine moist vortex Rossby wave dynamics analytically and computationally. One example shows that clouds can slow the growth of phase-locked counter-propagating vortex Rossby waves in the eyewal...
