Stereo photogrammetry applied to orographic cumulus

Joseph A. Zehnder
Arizona State University

The elevated terrain in the desert southwest of the United States provides an ideal location in which to observe the onset and development of deep convection. Thunderstorms associated with the North American Monsoon occur on a well-defined diurnal cycle, with shallow convection developing under typically clear skies over the highest peaks a few hours after sunrise. The shallow convection builds as a series of successively taller turrets that rise through the remnants of the preceding ones, transitioning into cumulus congestus and eventually cumulonimbus. This talk will provide an overview of the CuPIDO 2006 Field Experiment, which examined the initiation and development of thunderstorms over the Santa Catalina Mountains in southern Arizona. The emphasis will be on photogrammetric techniques and some examples of cumulus development and interaction of the convection with the environment will be presented.
