Current research projects include: MesoWest - Provides timely access to surface observations in the western United States to operational forecasters, the research community, and the public. Surface observations from a variety of federal, state, and local agencies are combined into a common data base. The ARPS (Advanced Regional Prediction System) Data Assimilation System (ADAS) is used to integrate the observations into analyses of surface weather conditions. Support for MesoWest is provided by a number of federal and state agencies and commercial firms. ROMAN (Real-time Observation Monitor and Analysis Network) - Provides current observations and analyses for use by the fire weather community. Support for ROMAN is provided by the Bureau of Land Management. METCRAX (Meteor Crater Experiment) - Investigates the formation and dissipation of nighttime cold air pools and seiches in Arizona's Meteor Crater. A one-month field experiment is planned from 1 October - 31 October 2006. This research program is funded by NSF's Mesoscale Dynamics Division with co-PIs Andreas Muschinski (U. Mass at Amherst), Sharon Zhong (U. Houston) and David Fritts (Colorado Research Associates). T-REX (Terrain-Induced Rotor Experiment) - Studies the development of mountain waves and rotors in the lee of the Sierra Nevada Mountains of California and investigates the relationship between boundary layer processes and rotors. We will compare and contrast the normal diurnal development of thermally driven circulations and boundary layers on days with and without lee waves and rotors. Field experiments were run by a large international team in the Owens Valley in March and April 2006. This research program is funded by NSF's Mesoscale Dynamics Division with co-PI Sharon Zhong (U. Houston). Great Salt Lake Studies- The level, salinity, and temperature of the Great Salt Lake respond to regional weather and climate through the interplay of the passage of storms, local evaporation, and the distribution of precipitation throughout the watershed of its closed basin. In turn, the Lake contributes to the development of lake breezes, lake breeze fronts, and lake-effect snowstorms that affect the populace of northern Utah. This research program is funded in part by NASA with PI Vince Salomonson.
