Lead Story: In Memoriam: Bill Lapenta

Spring 2020 | The DTC community mourns the passing of William “Bill” Lapenta, Ph.D. Bill was the Acting Director of NOAA’s Office of Weather and Air Quality (OWAQ) within NOAA’s Oceanic and Atmospheric Research that supports world-class weather and air quality research. He was also the guiding force and energy behind the Earth Prediction Innovation Center (EPIC) with the goal to launch the U.S. forward as the world leader in numerical weather prediction through public-academic-private partnerships. He was committed to conquering the… Read More

Director's Corner: A Look Ahead

Dorothy Koch

Spring 2020 |   At the National Weather Service’s Office of Science and Technology Integration (OSTI), we’re currently planning milestones for the coming year with our partners. OSTI manages a broad portfolio of research and development efforts designed to improve operational forecast capabilities, and our partners in these efforts are in both the research and operational communities. We aim to understand forecaster priorities, and to communicate operational requirements so that community members can come up with innovative solutions… Read More

Who's Who: LinLin Pan


Spring 2020 | LinLin was born into a family of farmers in Southeast China where the weather is dominated by the Asian Monsoon. “I can’t remember how many times my parents sighed gravely in front of the ruined crops because of the wrong prediction of Mei-yu – endless rainy days during the summer. My family would starve in this case.” LinLin was determined to study weather to help farmers, and now he works to make sure severe weather events are forecasted accurately. Diligent and determined, Linlin was accepted into the Department of… Read More

Bridges to Operations: MET Collaboration

Visitors: Evaluating the Impact of Model Physics on Forecasts of Hurricane Rapid Intensification

Visitor: Jun Zhang

Spring 2020 | Dr. Jun Zhang, a scientist from the University of Miami and visitor to the DTC in 2018, investigated the impact of model physics on the forecast performance of hurricane models for hurricanes undergoing rapid intensification (RI). Accurate predictions of hurricane intensity could significantly reduce the economic loss, especially if a hurricane makes landfall at well-developed coastal regions.  Hurricane intensity is influenced not only by environmental factors but also by internal dynamics and thermodynamics. Previous… Read More

Community Connections: Communication and Outreach in the Unified Forecast System

Spring 2020 | The Unified Forecast System (UFS) is a coupled, comprehensive Earth modeling and data assimilation system that will be used in NOAA operations and by the research community. There are naturally a lot of questions about UFS from potential collaborators, for example: What UFS codes are available to run? How do I find out more information about the project, and how can I get involved? One of the roles of the UFS Communication and Outreach Working Group (C&O WG, for short) is to communicate the answers to such questions… Read More

Did you know?: CCPP Framework

Is to be Used for Future Atmospheric Chemistry Modeling at NCAR

Spring 2020 |   The Atmospheric Chemistry Observations and Modeling laboratory at NCAR has been developing the Model Independent Chemistry Module (MICM) to represent chemical transformations in any atmosphere model. To make this happen, MICM is designed to work with the Common Community Physics Package (CCPP) Framework, a software defining how host models access physics parameterizations including chemistry. MICM gathers information on trace gases and chemical reactions from a database (coined the “Chemistry Café”). It then configures… Read More
