Summer 2017 | I grew up in Mound, MN, which is a western suburb of the Twin Cities. While most would consider Minnesota a cold and snowy state, I apparently wanted colder and snowier weather because I decided to head further north to Grand Forks, ND to attend the University of North Dakota (UND). I am an avid UND hockey fan and love heading to the games when they come out to play University of Denver or Colorado College in Colorado. Experiencing bitterly cold temperatures walking to class at UND certainly made me appreciate the… Read More
Who's Who: Man Zhang
Winter 2017 | As a visiting scientist at the University of Maryland in 2005, Man Zhang learned of Colorado’s reputation of being a great place to live. When her husband had an opportunity to come to Colorado as a visiting Ph.D. student, they didn’t think twice about moving. They love Colorado and have been in the Boulder area for almost 10 years. Man was a post-doc at CIRA in the ensemble data assimilation group. She applied the hybrid variational-ensemble data assimilation system (HVEDAS) developed at CIRA to the NOAA operational… Read More
Bridges to Operations: The Unified Post Processor
Summer 2017 | Post-processing is an essential but often overlooked component of numerical weather prediction and encompasses a broad range of concepts, methods, and tools to make raw model output more useful. The Unified Post Processor (UPP) can compute a variety of diagnostic fields, interpolate to pressure levels or specified (pre-defined or custom) grids, and de-stagger grids. Examples of the products include: T, Z, humidity, wind, cloud water, cloud ice, rain, and snow on isobaric levels SLP,… Read More
Bridges to Operations: The 2016 Hurricane WRF System
Winter 2017 | The community Hurricane Weather Research and Forecasting (HWRF) modeling system was upgraded to version 3.8a on November 21, 2016. This release includes all components of the HWRF system: scripts, data preprocessing, vortex initialization, data assimilation, atmospheric and ocean models, coupler, postprocessor, and vortex tracker. In addition to default operational features, the release includes capabilities to perform idealized tropical cyclone simulations run with alternate physics, and backwards compatibility for… Read More
Visitors: Evaluating Convective Structure
Visitor: Mariusz Starzec
Summer 2017 | As a visitor to DTC in 2016, University of North Dakota Ph.D. candidate Mariusz Starzec investigated the performance of regional summertime convective forecasts. In particular, he focused on model skill in predicting the coverage, morphology, and intensity of convection. Further emphasis was placed on how representative the simulated internal convective structure is of observed convection by using the reflectivity field as proxy for convective processes. Convection plays a major role in everyday weather and long term… Read More
Visitors: Cloud Overlap Influences on Tropical Cyclone Evolution
Visitors: Michael Iacono and John Henderson
Winter 2017 | As visitors to the DTC in 2016, Michael Iacono and John Henderson of Atmospheric and Environmental Research (AER) used the Hurricane Weather Research and Forecasting model (HWRF) to investigate an improved way of representing the vertical overlap of partial cloudiness and showed that this process strongly influences the transfer of radiation in the atmosphere and can impact the evolution of simulated tropical cyclones. Clouds are a critical element of Earth’s climate because they strongly affect both the incoming solar (… Read More
Community Connections: NGGPS Atmospheric Physics Workshop
November 2016
Summer 2017 | On 8-9 November 2016, more than 80 scientists from a broad cross-section of the physics development community gathered for the Next Generation Global Prediction System (NGGPS) Atmospheric Physics Workshop at the NOAA Center for Weather and Climate Prediction. The workshop provided an opportunity for the NGGPS Physics Team to revisit and refine its near- and long-term priorities for advancing the National Centers for Environmental Prediction (NCEP) global physics suite and identify key areas that need… Read More
Community Connections: Science Advisory Board Meeting - Sept 14-15
Winter 2017 | The DTC hosted its annual DTC Science Advisory Board (SAB) meeting on September 14-15, 2016. This annual event provides an opportunity for the DTC to present a review of DTC key accomplishments over the past three years to representatives of the research community and to collect input directed at shaping a strategy for the future. “The DTC enables and supports a wide variety of research-to-operations and operations-to-… Read More
Did you know?: Join Weekly Webinar Discussion on EMC’s Forecast Systems
Winter 2017 | You can join weekly webinars to discuss the performance of EMC’s forecast/analysis systems from a synoptic and mesoscale perspective. The weekly webinar is led by EMC’s Model Evaluation Group and participants include model developers, NCEP service centers, NWS regional and field offices, DTC staff, academic community and private sector. Webinars serve as a forum for… Read More
Did you know?: Documentation is important!
Summer 2017 | A Google Search: Documentation is the Most Valuable Thing You Do (from cyborginstitute.org/projects/administration/documentation/). Good documentation makes software and tools more valuable and more durable, and although documentation can be a great expense, in the long term it’s almost always worthwhile.
