| Abstract: | With observational data collected and interpreted by Crane et al. (1977), the adequacy of the O'Brien polynomial to represent the exchange profile of heat and pollution in a convective boundary layer is examined and a refinement suggested. Also, it is shown that the height of the surface layer, h=0.04 z i , developed by Blackadar and Tennekes (1968) for a neutrally stratified boundary layer (with z z =0.25u */f) appears to be equally valid for the convective boundary layer where z i , defined as the top of the mixed layer, is used. |
