Long-lived mesoscale convective systems over Eastern South Africa
… Africa have often focused on synoptic-scale systems such as cut off lows, tropical extratropical cloud bands, and tropical cyclones, with little attention placed on the smaller mesoscale convective systems (MCSs). On a global scale, MCSs are not only important as key rainfall producers, but …

Observed microphysical characteristics and inferred thermodynamic processes contributing to the structure, evolution, and maintenance of nocturnal elevated mesoscale convective systems
… NOAA P-3 aircraft across various regions of six mesoscale convective systems (MCSs) at multiple stages of system development. These spirals sampled MCSs corresponding to various archetypes, including several conforming to the classic leading-line/trailing-stratiform mode, and others conforming to …

Numerical simulations of mesoscale convective systems: techniques for comparison with observations and a high resolution analysis of flow patterns in the convective region and transition zone of a simulated mcs
… understanding of weather phenomena, such as mesoscale convective systems (MCSs). The Bow Echo and Mesoscale Convective Experiment (BAMEX) provides a multi-sensor, high-resolution dataset that can be used for such comparisons. In Chapter 2 of this work, airborne radar observations taken during …

Dusty gust fronts and their contributions to long-lived convection in West Africa/
… predict the behavior of West African storms and mesoscale convective systems (MCSs), we must understand the life cycle of gust fronts, which invariably accompany thunderstorms and often initiate them. In this thesis, I track 40 gust fronts observed during summer 2006 by the MIT radar in Niamey, …

Source air feeding convection within a nocturnal mesoscale convective system during the evolution from surface-based to elevated convection
… observed, the mechanisms that allow nocturnal mesoscale convective systems (MCSs) to persist are still not well understood. On 9 August 2014 at approximately 2000 UTC, a regime of upslope flow owing to a weak shortwave impulse in the lee of the Rocky Mountains spawned a convective complex near …

Idealized modeling of the role of stability and shear on mesoscale gravity wave evolution
Mesoscale Gravity Waves (MGWs) are large pressure perturbations that form in the presence of a stable layer at the surface either behind Mesoscale Convective Systems (MCSs) in summer or over warm frontal surfaces behind elevated convection in winter. MGWs are associated with damaging winds, …

Dependence of tropical cirrus clouds on sea surface temperature and consequences for the Archean climate
… climate of the Archean using a simple radiative-convective model that includes the effect of the variations in the area of thin cirrus clouds. First, we look at the variation in area of upper level clouds using TRMM VIRS (Tropical Rainfall Measuring Mission, Visible Infrared Sounder) data. We …

The role of land-atmosphere and aerosol interactions on meso-scale convective weather systems across West Africa
… and aerosol interactions on meso-scale convective systems across the sub-Saharan West Africa region, and aims at providing a value-added contribution towards better understanding of the controlling mechanisms for these interactions, in order to improve predictability of the highly …

How does terrain influence the upscale convective growth of orographic deep moist convection?
… that some of the world’s most intense deep convective storms occur near the Sierras de Córdoba, Argentina, South America. A ground-based radar climatology during two austral spring and summer seasons (2015–2017) revealed that most of the storms were multicellular and initiated most …

An analysis of heavy rainfall events over the Limpopo River Basin in southern Africa, their moisture sources and pathways
… events in the LRB and the associated weather systems. It was found that tropicalextratropical cloud bands account for almost half of the events and tropical lows are responsible for just over a quarter. The remaining quarter of the events are associated with mesoscale convective systems and …

High resolution numerical simulation of a nocturnal mesoscale convective system: Comparison with pecan observations
Nighttime convective storms produce a significant portion of warm season precipitation across the Great Plains region of the United States. The PECAN (Plains Elevated Convection at Night) project was designed to improve our understanding of how these storms can develop and maintain themselves in …
