Ronald B. Smith ; Department of Geology and Geophysics, Yale University, New Haven CT, USA

Abstract

The southern Andes create a variety of atmospheric phenomena, but these have not been well studied. In this paper, we describe our preliminary observations and modeling of a few of these phenomena including: the sharp vegetation gradient on the eastern slopes, orographic triggering of roll convection, foehn wall and short lee-wave [rains, liquid clouds capping ice clouds, "bullet" clouds, and isotopic fractionation of water vapor.
