Using Deep Learning to Improve Prediction and Understanding of High-impact Weather Ryan Lagerquist Wednesday, April 8th 11:00 am https://oklahoma.zoom.us/j/822210097 Zoom password: 596031 I describe the application of convolutional neural networks (CNN), a type of deep-learning method, to high-impact weather. CNNs are specially designed to learn directly from spatial grids, which improves both skill and interpretability. […]
Note: As part of the Spring 2020 the online framework, BUL seminars are offered live only to enrolled students and the speaker’s adviser(s) and committee. The live sessions are recorded and made available via the seminar’s mailing list and the BUL website. Distributions of Condensation Nuclei, Cloud Condensation Nuclei and Cloud Properties over the […]
Title: GLM and ABI characteristics of severe and convective storms. Time: Apr 3, 2020, 03:00 PM Central Time (US and Canada) Meeting Link: https://oklahoma.zoom.us/j/298115207 Meeting ID: 298 115 207 Abstract: The recent deployment of the Geostationary Lightning Mapper (GLM) on board GOES-16 and 17 provides a new perspective of total lightning production for the severe convective storms […]

Ohnstad Wednesday, April 1st 3:00pm Central Time (US and Canada)/Zoom Meeting Join Zoom Meeting https://oklahoma.zoom.us/j/505651584 Meeting ID: 505 651 584 Extreme winter weather is […]
Name: Dylan Reif Title: Initiation mechanisms of nocturnal convection without nearby surface boundaries Location: Online Date: 2020/03/31 Time: 02:00 PM Series: Boundary Layer, Urban Meteorology, and Land-Surface Processes Abstract: Nocturnal convection is common over the central and southern great plains. Nearly 25% of this convection initiates without any apparent surface convergence (i.e., far away from surface […]
Flash Drought Development and Cascading Impacts Associated with the 2010 Russian Heatwave Jordan Christian Wednesday, March 25th 3:00pm Central Time (US and Canada)/Zoom Meeting Join Zoom Meeting https://oklahoma.zoom.us/j/505651584 Meeting ID: 505 651 584 The 2010 western Russian heatwave was characterized by historically high surface temperatures that led to devastating impacts on the environment, economy, and […]
Name: Brian Greene Title: Characterizing Turbulence in Arctic Stable Boundary Layers During ISOBAR 2018 Location: NWC 5600 Date: 2020/03/24 Time: 2:00 PM Series: Boundary Layer, Urban Meteorology, and Land-Surface Processes Abstract: Operational numerical weather prediction models typically have effective resolutions too coarse to resolve turbulent processes in the planetary boundary layer (PBL). To overcome this restriction, […]
