Recent observations by Farman et al. reveal remarkable depletions in the total atmospheric
ozone content in Antarctica. The observed total ozone decreased smoothly during the period …

This report presents the details of the governing equations, physical parameterizations, and
numerical algorithms defining the version of the NCAR Community Atmosphere Model …

The influence of breaking gravity waves on the dynamics and chemical composition of the
60‐ to 110‐km region has been investigated with a two‐dimensional dynamical/chemical …

… the thinking of both Piaget and Garcia has been enriched and … In similar fashion, Rolando
Garcia, a student of Carnap and … Garcia has been led to envision in a new way the evolution …

Study Design. A prospective, randomized, multicenter, Food and Drug Administration-regulated
Investigational Device Exemption clinical trial. Objectives. The purpose of this study was …

Simulations of the stratosphere from thirteen coupled chemistry‐climate models (CCMs) are
evaluated to provide guidance for the interpretation of ozone predictions made by the same …

Ozone depletions in the lower stratosphere outside of polar regions are difficult to explain
using only local chlorine and bromine chemistry. We speculate that iodine chemistry in …

Middle atmospheric general circulation models (GCMs) must employ a parameterization for
small-scale gravity waves (GWs). Such parameterizations typically make very simple …

The dynamical response to localized, unsteady tropical heating is studied in a stochastic
framework. Spectral statistics of the random wave response are derived from those of tropical …

… The simulations discussed below use version 3 of the Whole Atmosphere Community Climate
Model (WACCM3), developed at the National Center for Atmospheric Research (NCAR), which …
