Scale-dependent-localization for global FV3GFS hybrid 4DEnVar data assimilation system Bo Huang OU School of Meteorology November 22 2019, 3:30 PM National Weather Center, Room 5600 Successful application of ensemble-based data assimilation (DA) relies on localization to reduce sampling error due to running a small ensemble. In a simple form, the localization function is defined […]
Name: Jeff Milne Title: Further exploring the vertical structure of updraft helicity Location: NWC 5600 Date: 2019/11/22 Time: 3:00 PM Series: Convective Meteorology (Mesoscale Dynamics) Abstract: Updraft helicity (UH) is a commonly used diagnostic output from convection-allowing models (CAMs) for forecasting severe convective weather. It is calculated by taking the vertical integral of the product of […]
Name: Dr. Jeremy Gibbs Title: Three Simple Ways to Add More Structure (Functions and Parameters) to Your Life Location: NWC 5600 Date: 2019/11/22 Time: 2:00 PM Series: Boundary Layer, Urban Meteorology, and Land-Surface Processes Abstract: Feeling lost? Not sure how to characterize the intensity of turbulent fluctuations of atmospheric flow variables? Well, look no further my […]
Name: Emily Tinney Title: Convective Influence on United States Upper Troposphere Lower Stratosphere Composition Location: NWC 5930 Date: 2019/11/20 Time: 03:00 PM Series: Weather and Climate Systems Abstract: It has been well demonstrated that deep convective storms can alter the composition of the upper troposphere and lower stratosphere (UTLS). A comprehensive and quantitative understanding of this […]
Name: Variability of In-Situ Observations and the Resulting Impacts in Meteorological Applications Title: Dr. Brad Illston Location: NWC 5600 Date: 2019/11/15 Time: 2:00 PM Series: Boundary Layer, Urban Meteorology, and Land-Surface Processes Abstract: In-situ meteorological observations have been collected for over 100 years and have demonstrated their critical use in forecasting, climatology, numerical modeling, and research […]
Name: Andrew Berrington Title: How Does the Madden-Julian Oscillation Circulation Affect its Propagation? Location: NWC 5930 Date: 2019/11/13 Time: 3:00 PM Series: Weather and Climate Systems Abstract: The Madden-Julian Oscillation (MJO) is one of the key links between global weather and climate, yet operational forecasts of the MJO continue to have shortcomings, especially pertaining to the […]
Name: Daniel Tripp Title: AN ASSESSMENT OF OKLAHOMA WINTER WEATHER THROUGH THE HIGH-RESOLUTION LENS OF UNMANNED AERIAL VEHICLES Location: NWC 5600 Date: 2019/11/12 Time: 2:30 PM Series: MASTERS THESIS DEFENSE Abstract: Winter weather can lead to power grid failures, disruption of transportation, and can impact the local economy. Specifically in the southern Great Plains, short term […]
