Abstract: Vertical velocity and temPerature data observed from Chaf and Faling SPhererocket S are used to study the str Ucture and generah0n 0f tUrbulence. ResultS indicatethat a mulh - layered turbulent statllre is observed. G0od cormlation is foundbetween the strong turbulent layer, dyndrical instability and radar echo power,suggeshng that the str0ng tuthulent lnyer and echo power are relared to the dynamicalinstability.Vertical wavenumber sPectrUm of h0rizonta wind indicares tha there is anexcellent agreement with the saturated spectral model, suggeshng that the strongturbulent layer and radar echo power are linked directly to the saturation of gravitywave motions via dynamical instability.
