Autumn 2017 | Faculty and graduate students at universities typically conduct basic research to better understand the fundamental workings of their area of interest, which in our field is the atmosphere. Transitioning these findings into practical applications, including operational weather forecasting, is then done by national labs and their cooperative institutes.  Yet in many cases, university researchers are working on problems that are directly relevant to operations, and have the potential (with a little help) to be considered… Read More

Autumn 2016 | NOAA’s testbeds and proving grounds (NOAA TBPG) are an important link between research advances and applications, and especially NOAA operations. Some are … Read More

Autumn 2017 | Evan knew he wanted to be a meteorologist when he was five years old -- every type of thunderstorm that blew through Kendall, FL enamored him. When Joe Cione, a hurricane researcher moved in across the street, his future career was sealed. After graduating in 2010 from Florida State University with a B.S. in meteorology, Evan moved to Boulder for graduate school at the University of Colorado, where he analyzed model simulations and radar data from supercell thunderstorms. Cione serendipitously moved to Boulder about the… Read More

Autumn 2014 | An old management adage says that if you need some new task done NOW, ask someone who is already busy. Although she probably cringes to hear it, this applies well to Tara, with an exception: she would first offer to take it on. Her tireless approach to work follows pretty directly from a commitment to accept new challenges in new places. In practice, it has led to twists and turns along the way. After completing her Master’s degree at Colorado State University in aerosol/cloud interactions in marine stratus, her graduate… Read More

Autumn 2017 | The terrain-following sigma coordinate has been implemented in many Numerical Weather Prediction (NWP) systems, including the Weather Research and Forecasting (WRF) model, and has been used with success for many years. However, terrain-following coordinates are known to induce small-scale horizontal and vertical accelerations over areas of steep terrain due to the reflection of topography in the model levels.  These accelerations introduce error into the model equations and can impact model forecasts, especially as… Read More

Autumn 2014 | Researchers from the DTC plan to provide numerical model runs from a preliminary version of the North American Rapid Refresh Ensemble system (Pre-NARRE) to the Hydrometeorological Testbed of the Weather Prediction Center (HMT/ WPC) during their current Winter Exercise. The DTC Ensemble Task will run the ensemble system (most likely on the NOAA hjet computing system) and post-process some of the results for HMT/WPC. Members of the ensemble (eight in total) will be produced from both WRF/ RUC and NMMB dynamical cores, and… Read More
