Robert S. Webb is Director of the NOAA Physical Sciences Laboratory (PSL) in Boulder, Colorado. His laboratory analyzes and interprets physical processes that influence weather and climate from hours to decades to provide scientific information to support NOAA's mission. Under Webb's direction, PSL works to improve predictions on weather-to-climate time scales by identifying early warning indicators in atmosphere and ocean patterns that cause extreme events (such as floods, droughts, and heat waves). The laboratory's research strives to improve observations, process understanding, modeling and predictions of weather, water and climate variations and extremes, and their related impacts.
