Short summary
The canopy convector effect in the context of canopy turbulence was recently introduced by Rotenberg and Yakir (Science, 2010). However, there was a lack of understanding of this phenomenon as a generic feature of canopy turbulence, as we have demonstrated in this paper. Uncertainties of existing parameterizations of canopy aerodynamic resistance to heat transfer are discussed and possible remedies are suggested.
