Evaporative Controls on Convective Adjustment: A Satellite-Based Assessment of Convective Available Energy (CAPE) During Surface Drydowns
… In convective atmospheres, convective available potential energy (CAPE) drives convective adjustment and can lead to precipitation. We study the evolution of CAPE during drydowns, interstorm periods over which evapotranspiration occurs, to understand the impact of evaporative controls …

Bridging the energy divide and securing higher collective wellbeing in a climate-constrained world
In spite of the impressive gains in available energy over the last two centuries, the associated benefits remain unevenly distributed. Bridging this divide only adds to the already daunting challenge of securing climate stabilization. This thesis examines the potential incompatibility between these …
