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, […]
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. Characterizing Turbulence in Arctic Stable Boundary Layers During ISOBAR 2018 Brian Greene – […]
Name: Joshua Gebauer Title: Impact of a Vertical Vorticity Constraint on Dual-Doppler Retrieved Vertical Velocity Location: NWC 5600 Date: 2020/03/13 Time: 3:00 PM Series: Convective Meteorology (Mesoscale Dynamics) Abstract: Previous observation simulation systems experiments (OSSEs) have found that a variational dual-Doppler retrieval with both a mass conservation and vertical vorticity constraint can improve retrieved vertical velocity, […]
Name: Montgomery Flora Title: Using machine learning to improve probabilistic forecasts of severe weather in the Warn-on-Forecast System Location: NWC 5600 Date: 2020/03/13 Time: 3:00 PM Series: Convective Meteorology (Mesoscale Dynamics) Abstract: A goal of the NOAA Warn-on-Forecast project is to provide rapidly-updating probabilistic guidance to human forecasters for short-term (e.g., 0-3 h) severe weather forecasts. An […]
Title: The Pacific Decadal Precession and its Relationship to Tropical and Extratropical North Pacific Decadal Variability Location: NWC 1350 Date: 2020/03/11 Time: 03:00 PM Series: Weather and Climate Systems Abstract: Recent research uncovered evidence of a quasi-decadal mode of climate variability, termed the Pacific Decadal Precession (PDP), a counterclockwise progression of an atmospheric pressure anomaly […]
