EOL/RAL Joint Seminar - Observed and Simulated Characteristics of a Persistent Cold Air Pool in the Columbia River Basin

Main content

Persistent cold air pools frequently form during wintertime in the Columbia River Basin in Oregon and Washington, which is home to a large amount of wind energy production. To integrate wind energy produced during cold-pool events into the electrical grid, accurate forecasts of these events are necessary, including the rapid changes in wind speed that often occur during the cold pool decay phase. In a first step, I used comprehensive in situ and remote sensing observations collected during the Second Wind Forecast Improvement Project (WFIP2) to study the spatio-temporal characteristics of a strong and persistent cold air pool and the involved processes. Second, I evaluated the forecast performance of three different versions of NOAA’s High-Resolution Rapid Refresh model (HRRR) during the cold-pool event.
