Linear Rayleigh-Taylor instability and Spread-F time behaviour in Tucuman, Argentina
Main Article Content
Abstract
The role of the zonal neutral wind (U) and the gradient scale length (L) is studied as contributions to the linear Rayleigh Taylor instability growth rate, in order to account for the temporal behaviour of F layer irregularities as detected in Tucuman (26°49'S, 65°13'W) from January 1978 to December 1988.
