Cloud Microphysical Properties Based On Airborne In Situ Observations And Evaluation Of A Weather Forecasting Model And A Global Climate Model, John D'Alessandro
Cloud Microphysical Properties Based On Airborne In Situ Observations And Evaluation Of A Weather Forecasting Model And A Global Climate Model, John D'Alessandro
Master's Theses
Global cloud coverage has a substantial impact on local and global radiative budgets. It is necessary to correctly represent clouds in numerical weather models to improve both weather and climate predictions. This study evaluates in situ airborne observations of cloud microphysical properties and compares results with the Weather Research and Forecasting model (WRF) and Community Atmosphere Model version 5 (CAM5). Dynamical conditions producing supersaturated conditions with respect to ice at high altitudes in regions diagnosed by convective activity are explored using observations taken from the Deep Convective Clouds and Chemistry (DC3) campaign, and results are compared with simulated data from …

The Diablo Winds Of Northern California: Climatology And Numerical Simulations, Carrie Lynn Bowers
Master's Theses
Extreme fire behavior in the San Francisco Bay Area (SFBA) has historically been associated with strong offshore wind events referred to locally as Diablo winds. A 17 year surface-based climatological analysis was performed to establish a definition of Diablo winds and to identify their frequency and spatial distribution. Synoptic composites of events were constructed using North American Regional Reanalysis, and high resolution Weather Research and Forecasting (WRF) model simulations were used to investigate the mesoscale dynamics of three significant Diablo wind events. Diablo winds were defined as dry northeasterly, downslope winds that occur in the SFBA with minimum sustained wind …
