Dynamics of Convective Scale Interaction

Abstract

Movies made from high resolution geostationary satellite data, Bohan (1981) show that convective scale interaction (CSI), Purdom (1979), is of primary importance in determining the development and evolution of deep convection. CSI is directly associated with outflow boundaries produced by precipitating convective storms. CSI manifests itself as the merger and intersection of those outflow boundaries (arc cloud lines, Purdom (1973) with other convective areas, lines and boundaries. Under the proper atmospheric conditions, this interaction has been observed to precede tornadic storm development, Purdom (1984, 1986). CSI is fundamental in the evolution and maintenance of deep convection; it is complex because of the continuously evolving nature of the convective environment. Until recently (Wilson and Carbone, 1984), CSI had only been observed using satellite imagery. Reprints.
