About HAP

Providing relevant information to water resource decision makers

The main goal of the Hydrometeorological Applications Program is to provide relevant information to high-impact weather, flood warning, and water resource decision makers through directed and basic research and development in hydrometeorology, aerosol-precipitation interactions, very short term precipitation nowcasting, cloud microphysical modeling, and winter weather.

Applications focused on water resources, flood warnings and control, winter weather precipitation events, and weather modification are growing at a rapid rate. Earth’s water supply, when considered on a regional basis, may not be sustainable relative to agricultural and industrial practices of the last century. RAL is motivated to building this research area to meet the needs of national (federal, state, county and municipal) and international organizations in the public and private sectors and to make a significant contribution to the science of hydrometeorology.

Webcast - The Great Front Range Flood of 2013
Rita Roberts1, Jenny Sun1, Dave Gochis1, Barbara Brown1, and Matt Kelsch2

The deadly flood that occurred in the Front Range during the week of September 10th, 2013 is believed to be the worst in the state’s history. It claimed several lives and damaged numerous homes and roads. In the context of NCAR’s Short-Term Explicit Prediction (STEP) program, an effort is underway to understand the flood event and to improve our forecasting of future heavy rainfall and flood events. In this seminar, we will present what has been learned so far from observations and modeling, including coupled hydrologic modeling. We will also discuss a vision for an end-to-end hydrometeorological prediction system for tackling the challenging problem of flash flood prediction.
