Abstract: phenomenological model is developed wherein vortices are introduced at random into a virtual arena with specified distributions of diameter, core pressure drop, longevity, and translation speed, and the pressure history ...

Abstract: The authors describe the design and performance of inexpensive and compact time-lapse cameras suitable for field deployment in remote locations for long periods and their application to studying two time-variable meteorological ...

Abstract: A scalemodel bluntcone capsule intended for ocean splashdown was projected into a water pool to evaluate impact loads and postimpact behavior. In a small region of the speed/angle parameter space, the capsule would ...

Abstract: hree decades of weather records at meteorological stations near Death Valley National Park are analyzed in an attempt to gauge the frequency of conditions that might form and erase the famous trails of wind-blown rocks in ...
