Advancing Probabilistic Prediction of High-Impact Winter Storms through Ensemble NWP and Post-Processing

Funded ProjectsBy Kristina Kiest August 15, 2022

The Weather Program Office is working with the University of Utah to improve snowstorm prediction capabilities for forecasts 48 hours to 7 days in advance using techniques and advanced ensemble numerical modeling. Researchers are developing and testing new snow-to-liquid-ratio (SLR) algorithms to improve snowfall forecasts derived from numerical modeling systems, and evaluating and improving methods…

Researchers and Forecasters Team Up to Improve Forecasts in the New Hurricane and Ocean Testbed

Funded Projects, WPO NewsBy Kristina Kiest August 15, 2022

After a year and a half of concerted effort between NOAA’s National Hurricane Center (NHC), Atlantic Oceanographic and Meteorological Laboratory (AOML), and other NOAA offices, including the Weather Program Office, the Hurricane and Ocean Testbed (HOT) has been successfully re-named (from the Joint Hurricane Testbed) and re-launched in the newly designed William M. Lapenta Laboratory, named in…

Saildrones Track Hurricanes to Gather Data for Forecast Improvement

Funded Projects, WPO NewsBy Kristina Kiest August 15, 2022

In partnership with NOAA, Saildrone Inc. is deploying seven ocean drones to collect data from hurricanes during the 2022 hurricane season with the goal of improving hurricane forecasting. For the first year, two saildrones will track hurricanes in the Gulf of Mexico. One of the biggest challenges to hurricane forecasting is predicting rapid intensification, when hurricane…

Ensemble Prediction and Predictability of Extreme Weather via Circulation Regimes

Funded Projects, WPO NewsBy Kristina Kiest August 12, 2022

A presentation given at NOAA’s 46th Annual Climate Diagnostics and Prediction Workshop used cluster analysis methods to investigate and forecast circulation regimes impact on weeks 3/4 predictions. This study demonstrates that the dominant circulation regimes over North America are combinations of teleconnections where the clusters are related to temperature and precipitation anomalies. The computationally efficient…

Advances in the Prediction of MJO Teleconnections in the S2S Forecast Systems

Funded Projects, WPO NewsBy Kristina Kiest August 12, 2022

A recent study uses novel diagnostics to evaluate the ability of 11 state-of-the-art Subseasonal to Seasonal (S2S) forecast systems to represent the teleconnections of the Madden-Julian Oscillation (MJO) and the impact on mid-latitude weather systems and prediction. Several S2S program funded projects contributed to this work. While highlighting where model developments may be most beneficial…
