Despite over 70 years of extensive research, the factors controlling how clouds entrain environmental air are still not well understood, a problem contributing to the poor quantitative precipitation forecast skill of ...

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 ...

The primary goal of this research was to quantify occurrence frequencies of the two main proposed mechanisms of tornadogenesis in quasi-linear convective systems (QLCSs), namely, tilting and stretching (T&S) and HSI and ...

El Nino Southern Oscillation (ENSO) can have global impacts across the world. Because of its prevalence, scientists run models to forecast its next move. Here, long-short-term-memory models (LSTM) were compared to linear ...

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 ...

The principal objective of this study is to determine whether or not the penetration of a passive tracer is analogous to the penetration of a greenhouse-gas-induced heating.
