ARLEN W. HUGGINS

Associate Research Scientist
Atmospheric Sciences Division

B.S., Physics, Kansas State University
Graduate Study (36 hours), Atmospheric Science, Colorado State University

PROFESSIONAL INTERESTS:

Mr. Huggins has an active interest in applied research in both summer convective storms and wintertime storms. He has used ground-based microwave radiometers and radars, aircraft data and precipitation data to study the evolution of winter storms over mountainous terrain, including field projects in the Sierra Nevada of California and Nevada, the Wasatch Mountains of Utah and the Victorian Alps of Australia. As a researcher on U.S. Bureau of Reclamation and NOAA-sponsored weather modification projects, Mr. Huggins has studied the physical effects of both airborne and ground-based cloud seeding on winter storm clouds, and produced several publications documenting the effects of seeding from cloud to ground. He is the Director of the Nevada State Weather Modification Program, which is designed to augment snowfall in selected mountainous regions of Nevada. Recent work includes the testing and modification of National Weather Service NEXRAD precipitation algorithms in both summer and winter storm situations, using data from high altitude radars in the intermountain regions of the western U.S.
