Science / What drives wind, including the Jet Stream?
« on: May 27, 2013, 06:11:53 PM »
Why does this group accept differential heating as a driver for wind and reject condensation induced atmospheric dynamics?

The conventional differential heating have failed to adequately predict ice melt in the Arctic and seasonal changes in the jet stream.  And yet, when Makarieva  et al offer up a model that suggests heat transport into the Arctic is at least an order of magnitude greater than the old theory forecast, Makarieva et al is ignored.

In the comments in the discussion paper, it is clear that Makarieva et al do not consider the case of condensation onto a cold surface as in a moist wind flowing over the GIS or sea ice.  I assert, that consideration of the surface condensation case generates meridional winds that better explain seasonal changes in the NH circulation than, say the Rossby wave modeling by  Dr. Francis.

I am sorry,  but I see convention weather theory as deeply flawed in its ability to quantitatively account for the effects of latent heat. Makarieva et al is not a finished product.  My copy is covered with notes in red and purple.  These out number my notes in green. However, when it has been folded into weather theory and well baked, we will have something that is better.
