PhD Defense Expert-Guided Machine Learning for Meteorological Predictions Across Spatio-Temporal Scales Amanda Burke Tuesday, July 2nd, 2024 Zoom / 12:00 pm https://oklahoma.zoom.us/j/94120953482?pwd=w0hj5XwYsWb5mTsxuoeE6FrysEbKO8.1 Abstract: In satellite imagery, above-anvil cirrus plumes (plumes) serve as critical indicators of impending severe weather, often appearing 30 minutes before reported events. Their real-time identification is particularly valuable in radar-deficient regions, where […]
Thesis Defense Subgrid Scale Modeling of Turbulence and Cloud Microphysics Interactions Claire Doyle Friday, June 21st, 2024 NWC 5600 / 10:00 am Abstract: Clouds have a significant but uncertain impact on Earth’s climatological and hydrological cycles. In particular, the warm rain process has considerable inconsistencies between current theories and observations. One hypothesis to explain this […]

Thesis Defense Tropopause Polar Vortex Linkages to Arctic and Midlatitude Phenomena Tomer Burg Friday, May 30th, 2024 12:30 pm / NWC 5600 Abstract: Tropopause polar vortices (TPVs) are coherent, closed tropopause-based vortices that spend at least 60% of their lifetime poleward of 65° latitude. TPVs are most common in the Arctic, where they are often […]
Research Seminar Hydrometeorological extremes in a changing climate Xiaodong Chen Monday, May 13 NWC 1313 / 3:00 PM Changing climate in the Earth system has been causing more frequent and intense extreme events across scales. Our society is now faced with two key challenges regarding the water cycle: 1) understanding and predicting the evolving hydrological […]
Teaching Demonstration Overview of Earth’s water cycle Xiaodong Chen Monday, May 13 NWC 1120 / 10:00 AM Water cycle is a critical component in the Earth system, interacting with a variety of other Earth system components. Within the water cycle, different water storages possess unique properties and connect to diverse elements in the Earth system. […]
Masters Thesis Defense Optimization and Validation of MAIA Aerosol Retrieval Using POLDER Observations Benting Chen Monday, May 13th NWC 1350 / 9:00 AM If unable to attend in person Join Zoom: https://oklahoma.zoom.us/j/98689896271?pwd=WGpBZkt2VUU0SzRYZDMvaHBJS2QvZz09 Abstract: NASA’s Multi-Angle Imager for Aerosols (MAIA) is a satellite-borne multi-angle polarimeter (MAP) instrument aims at investigating the human health effects caused […]
Weather and Climate Systems Characteristics of large-scale circulation “forecast busts” over Europe in ERA5 (re-)forecasts Seraphine Hauser Wednesday, May 8th NWC 1350 / 3:00 pm Abstract: Despite rapid improvement in global-scale numerical weather prediction systems, forecast centers repeatedly experience notable declines in their systems’ forecast accuracy. These occasional very poor forecasts are often referred to […]
