Abstract: The ability of coupled atmosphere?ocean general circulation models (AOGCMs) to simulate variability in regional and global atmospheric dynamics is an important aspect of model evaluation. This is particularly true for ...

Abstract: In this study the vertical convergence of the eddy heat flux, found as a forcing term in the thermodynamic energy equation of the transformed Eulerian mean formulation, is estimated in the troposphere and in the lower ...

Abstract: Future projections of near-surface ozone concentrations depend on the climate/emissions scenario used to drive future simulations, the direct effects of the changing climate on the atmosphere, and the indirect effects of ...

Abstract: he fourth in a series of four articles on historical and projected climate extremes in the United States. Here, we examine the results of historical and future climate model experiments from the phase 5 of the Coupled Model ...

Abstract: of knowledge regarding trends and an understanding of their causes is presented for a specific subset of extreme weather and climate types. For severe convective storms (tornadoes, hailstorms, and severe thunderstorms), ...

Abstract: ntific assessment examines changes in three climate extremes?extratropical storms, winds, and waves?with an emphasis on U.S. coastal regions during the cold season. There is moderate evidence of an increase in both ...

Abstract: nd climate extremes have been varying and changing on many different time scales. In recent decades, heat waves have generally become more frequent across the United States, while cold waves have been decreasing. While ...

Abstract: nder the Federal Aviation Administration?s (FAA) Aviation Climate Change Research Initiative (ACCRI), non-CO2 climatic impacts of commercial aviation are assessed for current (2006) and for future (2050) baseline and ...
