We are broadly interested in scale interactions in the atmosphere and how best to represent these in weather and climate models in order to build resilience in water-susceptible regions. At the moment, we are focused on mesoscale convective systems as a specific instance of this atmospheric scale problem. Mesoscale convective systems are aggregations of thunderstorms that extend over hundreds of kilometers and bring the majority of extreme rainfall throughout the tropics. Their intermediate size in the spectrum of atmospheric phenomena means that they are influenced by both the smallest scales (like ice crystal or droplet formation, called cloud microphysics) and the largest scales (via circulation patterns like the Hadley cell). We are working to understand the smallest scales through benchtop experimentation and idealized parcel modeling and the largest scales through high-resolution storm-resolving simulations.
Clouds and their Climatic Impacts
Sylvia led the editing of a new volume now available through AGU Geophysical Monographs on Clouds and their Climatic Impacts. It is available through Wiley, Amazon, and Barnes & Noble. A short piece was published on it here by Editors’ Vox blog at AGU.
