      Diffusive Fluxes. Sensible heat flux. The density of sensible energy is. ... These can easily be converted to latent heat fluxes as well by simply multiplying the evaporative flux equations by Lv. where F is the flux of water vapor from (or onto) the surface, ra is the density of air, U is the near surface wind speed, qs is the surface mixing ...

      Latent heat flux (W/m2). Figure 5. Sensible heat flux (W/m2). Finally, lets look at changes in ground temperature and canopy temperatures. We see results that are similar to the heat fluxes. Figure 6 shows the temperature of the ground, looking at it we can see that grasses have the highest temperatures, then shrubs, and crops have the lowest ...

      Sensible heat fluxes were corrected for differences between the sonic temperature and the actual air temperature (Schotanus et al. 1983). Both the sensible and latent heat fluxes were corrected for misalignment with respect to the natural wind coordinate system (Baldocchi et al. 1988).

      The Southern Great Plains (SGP) carbon dioxide flux (CO2 flux) measurement systems provide half-hour average fluxes of CO2, H2O (latent heat), and sensible heat. The fluxes are obtained by the eddy covariance technique, which computes the flux as the mean product of the vertical wind component with CO2 and H2O densities, or estimated virtual ...

      Diffusive Fluxes. Sensible heat flux. The density of sensible energy is (1) We have to be a bit careful in the vertical because of compressional effects that are not relevant to vertical energy exchange. Note that for adiabatic processes, q is conserved and no heat is exchanged.

      Additionally, the latent heat flux is also a function of humidity so that on a calm humid day the transfer of both sensible and latent heat fluxes will be less than it would be for windy and dry conditions. 10-11. On a clear still night over land, the surface temperature usually (increases, decreases) if a low cloud moves overhead. Explain.

      The Bowen radiation energy balance technique (BREB) can be used to calculate sensible and latent heat fluxes at the surface (Fritschen and Simpson 1988). Fritschen (1988) utilizes data provided by an experiment called ASCOT, conducted in 1984, to provide alternate methods to calculate surface and latent heat fluxes.

      Once PCAPs are established, many other factors that affect radiative and sensible and latent heat fluxes at the surface and within the entire depth of the PCAPs become important, e.g., time of year, presence of low clouds within PCAPs and mid- and high-level clouds above them. Figure 1 illustrates many of these meteorological processes.
