Linear Rayleigh-Taylor instability and Spread-F time behaviour in Tucumán, Argentina

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 Tucumán (26°49'S, 65°13'W) from January 1978 to December 1988.
