The UA's Department of Hydrology and Atmospheric Sciences now offers the nation's first graduate degree program (MS, PHD), with a major in Hydrometeorology. The terrestrial water cycle includes both the atmospheric component--water vapor, clouds, and precipitation--and the land component--surface and subsurface runoff, infiltration, evapotranspiration, snowmelt, river flow--which play a major role in the weather and climate and strongly affects human activities.
Historically, the science of hydrology has focused on land-related processes and has relied on prescribed atmospheric inputs, generally from observations or atmospheric model outputs, or through empirical estimates derived from conventional meteorological measurements. In contrast, while the atmospheric sciences generate hydrologically-relevant forecasts, they tend to avoid dealing with the details of processes influencing feedbacks generated by the land surface. In establishing a firm linkage between the two, the program asks the following questions:
- What is the science involved with the interface of water in the atmosphere and water on the ground?
- What are the ramifications for predictive capabilities when these processes are incorporated into coupled numerical weather and climate models?
- What are the new applications in water quality, and how are water quality issues linked to precipitation and related runoff issues?
- How is the full understanding of the hydrologic cycle from "white water" to "blue water"--from precipitation to streams to oceans to water vapor to precipitation--related to the advancements in prediction and related societal benefits that link back to the water quality issue?
The purpose of the program is to:
- Educate students by providing them with (1) a well-rounded background in the fields of atmospheric, hydrologic, and systems sciences, (2) the tools and methods for numerical modeling, prediction, and data assimilation (surface hydrology, weather and climate), and (3) the sensors, data sources, and data manipulation tools, including remote-sensing and geographic information systems (GIS)
- Partner with various national and international weather and climate forecasting agencies to identify critical hydrometeorological knowledge gaps, to support, encourage, and facilitate research in multidisciplinary hydrometeorological science, and to work towards improved forecasts and forecast support, particularly over arid and semiarid regions such as the Western US
- Serve the hydrometeorological science and operational communities by coordinating meetings and workshops seeking to build consensus related to hydrometeorological science and to assist in the transfer of advances in understanding into the decision-making arena
