Improving numerical weather prediction: error growth at the convective scale and speed
… area where NWP is in need of improvements is convective-scale forecasting. The advantages of more accurate forecasting derive from the high societal impact of convective events, which can be severe and lead to loss of life and property. Ensemble forecasting is an ideal tool to handle …

The assimilation of surface observations in the European Alpine region
… chain to obtain refined weather forecasts at the convective scale. The setup was developed using technical choices aimed at making the system affordable for a private meteorological service with limited computational resources. The goal is to build a timely NWP system capable of quickly and …

Climate change and hazardous convective weather in the United States: Insights from high-resolution dynamical downscaling
… projections increasingly suggest that large-scale environmental conditions favorable for hazardous convective weather (HCW) may increase in frequency in the future due to anthropogenic climate change. However, this storm environment-based approach is undoubtedly limited by the assumption that …

GREMLIN: GOES radar estimation via machine learning to inform NWP
… scenes for the purpose of improving short-term convective-scale forecasts of high-impact weather hazards. The hypothesis of this dissertation is that by harnessing the power of ML, the new GOES-R capabilities can be used to create equivalent radar reflectivity suitable for initializing …

Simulating organization of convective cloud fields and interactions with the surface
The mesoscale organization and structure of convective clouds is thought to be rooted in the thermodynamic properties of the atmosphere and in the turbulent to mesoscale dynamics of the flow. Such structure may contribute to the transition between shallow and deep convection. The thermodynamic …

Multi-scale interactions leading to tropical cyclogenesis in sheared environments
… because TC development involves a wide range of scales from the stochastic convective scale to a quasi-balanced large-scale flow. This dissertation examines the factors that increase uncertainty around the multi-scale tropical cyclogenesis problem, namely, vertical wind shear (VWS), environmental …
