[Aus-soaring] Cloud proof fence

http://www.nytimes.com/2007/08/14/science/earth/14fenc.html The article is ancient but I thought it was fascinating nonetheless. Often I've seen cumulus form over the sunset country but not elsewhere when flying out of Waikerie or Horsham. Apparently it's not a coincidence. ___

Matthew, Here's the link to the actual paper. There are others in the research repository. Search for Lyons,Nair http://researchrepository.murdoch.edu.au/4041/ This is a climatological study. I think the clouds on any given day over the scrub may be for other reasons. Particularly late i

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 t

You need to understand the geography and climate of SW W.A. The wheatbelt is the area in the SW where the rainfall is high enough to grow wheat. Check out any satellite photos of the area. The rabbit proof fence is the limit of that area pretty much. I had a pal in physics at UWA in the late

Excellent, Thanks Mike. That explains a lot more than the paper ever did. Clearly if the settlers cleared land as far east as they could to grow wheat, then the rainfall has a fairly difined boundary. The fence does not stop the rain nor the clouds. There does seem to be a sort of dividing li
