Sentences with phrase «deep convection takes»

Firstly, we know that there is a great deal of decadal variability in how much and where deep convection takes place.

Not exact matches

In fact the shortwave energy absorbed during the tropical summer at depth remains there until the winter when the humidity falls enough so that evaporative cooling sets up strong enough vertical convection to overcome the shallow diurnal reversals in the topmost one to three meters and dredge those deeper waters up to surface where some more rapid cooling can take place.

Processes taken into account included (i) air mixing by pressure and temperature gradients down to a few meters below the surface (i.e., the so - called convection zone); (ii) molecular diffusion in the open pore space and gravitational fractionation (entrainment toward the deeper firn depends on concentration gradients, diffusivities, and molar mass); and (iii) a downward air flux in the open porosity zone due to bubble closure removing air from the open pores.
