In this paper, repeated aircraft runs at about 33 m over heterogeneous terrain are analyzed to study the spatial variability of the mesoscale flow and turbulent fluxes in the inland breeze.Abstract:
Repeated aircraft runs at about 33 m over heterogeneous terrain are analyzed to study the spatial variability of the mesoscale flow and turbulent fluxes. An irrigated area, about 12 km across, generates a relatively cool moist inland breeze. As this air flows out over the warmer, drier surrounding land surface, an internal boundary layer develops within the inland breeze, which then terminates at a well-defined inland breeze front located about 1½ km downstream from the change of surface conditions. This front is defined by horizontal convergence, rising motion, and sharp spatial change of moisture, carbon dioxide, and ozone. Both a scale analysis and the observations suggest that the overall vertical motion associated with the inland breeze is weak. However, the observations indicate that this vertical motion and attendant vertical transport are important in the immediate vicinity of the front, and the inland breeze does lead to significant modification of the turbulent flux. In the inland breez...read more

Influence of the spatial distribution of vegetation and soils on the prediction of cumulus Convective rainfall
TL;DR: In this article, the Earth's surface role with respect to the surface energy and moisture budgets is examined, and changes in land surface properties are shown to influence the heat and moisture fluxes within the planetary boundary layer, convective available potential energy, and other measures of the deep cumulus cloud activity.

On micrometeorological observations of surface-air exchange over tall vegetation
TL;DR: In this paper, it is shown from the mass conservation and the continuity equations that the net ecosystem exchange (NEE) of a scalar constituent with the atmosphere should be NEE =∫ z r 0 ∂ c ∂t d z+( w′c′ ) r + w r c r − 1 z r ∫ zr 0 c d z where the first term on RHS is the storage below the height of observation (zr), the second term is the eddy flux, and the third term is a mass flow component arising from horizontal flow convergence
