Abstract: Gradients of temperature and humidity above water surfaces are analyzed in order to determine the dependence of the long-term average Bowen ratios ? (the ratio of sensible to latent heat flux) on surface temperature. The ...

Abstract: From a review of experimental evidence it is concluded that in confined bodies of water the ratio of surface drift to surface friction velocity, us, u* is a function of water depth that precludes the application of ...

Abstract: Data from a recent experiment indicate that the height scale for wind in the planetary boundary layer is u*/F, where u*/F is the friction velocity and f the Coriolis parameter, rather than zi, the height of the convection-limiting ...

Abstract: Following a suggestion by Deardorff, Hess et al. have proposed that a necessary condition for the formation of dust devils is ?h/L?50, where h is the convective boundary layer height and L the Obukhov length. A survey of ...

Abstract: Observations of funnel clouds over Port Phillip Bay, Victoria, Australia, indicate that they occur during outbreaks of cool air from the Southern Ocean advecting over the relatively warm bay waters. These clouds act as ...

Abstract: National weather services now receive global model forecasts from a number of centers around the world. The existence of these forecasts raises the general question of how the operational forecaster can best use the ...

Abstract: A 4-day photochemical smog event in the Melbourne, Victoria, Australia, region (6?9 March 2001) is examined to assess the performance of the Australian Air Quality Forecasting System (AAQFS). Although peak ozone concentrations ...
