Every year, a majority of all Atlantic hurricanes originate from African easterly waves. Yet, less than 20% of all African waves originate tropical cyclones (including hurricanes). It is of interest to investigate if African ...

Relationships between synoptic activity and sea ice variability in the Arctic are studied using self-organizing maps (SOMs) to categorize observed weather patterns over the 1979-2010 period. The European Centre for ...

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 projected increase in global air traffic raises concerns about the potential impact aviation emissions have on climate and air quality. Previous studies have shown that aircraft cruise emissions (emitted between 9-11 ...

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 ...

Since the advent of dual-polarization radar, methods of classifying hydrometeors by type from measured polarization variables have been developed. However, the deterministic approach of existing hydrometeor classification ...

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 ...
