Abstract: The Zilitenkevitch relation for nocturnal boundary-layer (NBL) depth h in terms of scales u*/f and L is necessarily a poor predictor of h when single-point values of surface fluxes are used. This is because the latter are ...

Abstract: Aspects of the land-surface and boundary-layer treatments in some 20 or so atmospheric general circulation models (GCMS) are summarized. In only a small fraction of these have significant sensitivity studies been carried ...

Abstract: The Cold Fronts Research Programme (CFRP) concentrated upon cold frontal systems (synoptic scale fronts) occurring in southeast Australia during late spring and early summer (November and December); many of these tend to ...

Abstract: Observations of wind stress and wind profiles over the ocean reported in the literature over the past 10 years are consistent with Charnock's (1955) relation between aerodynamic roughness length (z0) and friction velocity ...

Abstract: There are numerous reports in the literature of observations of land surface temperatures. Some of these, almost all made in situ, reveal maximum values in the 50°?70°C range, with a few, made in desert regions, near 80°C. ...

Abstract: Evidence is presented that the excess surface net radiation calculated in general circulation models at continental surfaces is mostly due to excess incoming shortwave fluxes. Based on long-term observations from 22 worldwide ...

Abstract: An evaluation of the clear-sky longwave irradiance at the earth?s surface (LI) simulated in climate models and in satellite-based global datasets is presented. Algorithm-based estimates of LI, derived from global observations ...

Abstract: There is direct evidence that excess net radiation calculated in general circulation models at continental surfaces [of about 11?17 W m?2 (20%?27%) on an annual basis is not only due to overestimates in annual incoming ...

Abstract: For representative tropospheric profiles of water vapor, CO2 and temperature we have calculated in situ longwave radiative flux divergence for use in a simplified second-order closure model of nocturnal boundary-layer ...
