This study first provides an overview of the dynamic and thermodynamic evolution of tropical easterly waves (TEWs) for 164 named tropical storms over the Atlantic during 1989-2010 July-October. The evolution of precipitation ...

The first part of this thesis is a study of the dynamics of storm tracks from the perspective of local instability of a class of zonally inhomogeneous basic jet streams. An unstable local mode consists of a group of dominant ...

The composition and properties of black carbon aerosol particles change continuously after emission during transport in the atmosphere. Coagulation, condensation, and photochemistry are contributing processes, collectively ...

Decadal mean temperatures show a warming over the past 60 years at individual stations in Alaska. This research examines corresponding changes in frequencies of extremes of temperature and precipitation based on daily ...

Warm, tropical boundary clouds represent one of the biggest sources of uncertainty in climate sensitivity to anthropogenic forcing. Information useful for gaining a better understanding about such clouds is relatively ...

Arakawa and Schubert (1974) developed a cumulus parameterization scheme in a framework that conceptually divides the mutual interaction of the cumulus convection and large-scale disturbance into the categories of large-scale ...

Data acquired by the National Research Council of Canada (NRC) Convair-580, equipped with cloud and aerosol probes during 5 sorties through single-layer arctic stratocumulus on 8 April, 18 April, and 26 April 2008 during ...

To understand and resolve uncertainties regarding climate change, accurate observations must be utilized. Satellite remote sensing provides the best way to obtain global observations, yet the assumptions required to convert ...

The stratospheric final warming is the final transition of the zonal winds from wintertime westerlies to summertime easterlies as the solar heating of the high latitude stratosphere increases in the springtime. Recent ...

We are interested in establishing how the instability properties of the background circulation might be related to the observed intraseasonal variability. We focus on the intraseasonal variability in two Northern Hemispheric ...
