Modelo simplificado para turbulência na camada limite noturna
(Universidade Federal de Santa Maria, 2016-03-08)
The appropriate estimation of turbulent fluxes in very stable conditions is a great challenge
for numerical models that simulate the average behavior of the stable boundary layer.
Although many features of the flow are ...
