Figure 10From: The dynamics of the mesosphere and lower thermosphere: a brief review Momentum flux spectrum. Spectra of momentum flux (\(\rho _{o}\overline {u^{\prime }w^{\prime }}\)) in mPa for total (solid), upward going (dashed) and downward going fluxes (dash-dot) derived from SPB observations over Antarctica, September to October 2010.Back to article page
