Abstract: The eddy diffusion coefficient Kyy has been calculated using LIMS data for the months of December 1978 and January and February 1979. Two methods have been used. The first implements the suggestion made by Tung (1987) to ...

Abstract: It has been well established that the atmosphere is chaotic by nature and thus has a finite limit of predictability. The chaotic divergence of initial conditions and the predictability are explored here in the context of ...

Abstract: arge-scale Rossby normal modes are studied for the Northern Hemisphere winters of 2005, 2006, 2008, and 2009 using global observational meteorological analyses spanning the 0?92-km altitude range. Spectral analysis of ...

Abstract: It is recognized that the resolved tropical wave spectrum can vary considerably among general circulation models (GCMs) and that these differences can have an important impact on the simulated climate. A comprehensive ...

Abstract: The response of stratospheric climate and circulation to increasing amounts of greenhouse gases (GHGs) and ozone recovery in the twenty-first century is analyzed in simulations of 11 chemistry?climate models using ...
