Thanks Robert, Just to clarify for me.
"The latent heat flux is the movement of heat energy from the surface to altitude associated with the evaporation of water at the surface and its condensation at altitude in clouds." I take it that, Latent heat flux is one of the effects which generates thermals. The other is sensible heat ie ground gets hot, transfers heat to near surface air by conduction. Air then rises (convection). Do you have any thoughts on why the natural vegetation (we used to call it scrub) has a strong bias to Latent Heat Flux in December but not in August?
