Providing relevant information to water resource decision makers

The Hydrometeorological Applications Program works to understand how water vapor, precipitation, and land surface hydrology interact across scales to define the hydrological cycle. Research results are used to improve weather and climate forecasts and to aid decision makers in a variety of water resource management applications such as flash flood prediction.

Microphysics and Aerosols

There is growing evidence that human activities can alter atmospheric processes on scales ranging from local precipitation patterns to global climate. Research and documentation of anthropogenic effects on precipitation processes strengthen the physical basis for deliberate attempts to alter clouds with the goal of enhancing precipitation. The potential for such man-made increases in precipitation is strongly dependent on the natural microphysics and dynamics of the clouds that are to be seeded.

Watercycle Research

While the water cycle is a global problem, increased knowledge over the CONUS will lead to significantly better understanding and prediction of key aspects, on scales ranging from storm-scale to climatic fluctuations. This improvement has the potential to dramatically alter the public’s ability to plan for and react to significant weather events. This effort begins by understanding how water vapor, precipitation, and land-surface hydrology interact across scales to define the hydrological cycle up to a continental scale, and thus improve large-scale prediction models. A key area of research will be to better understand and measure the components of the water cycle work together as a coupled system.
