Abstract

The evolution of the mixing layer height, both diurnal and nocturnal and the nocturnal planetary boundary layer height has been evaluated at the Central Nuclear de Almaraz, Spain in a winter period. Results show that a surface-based stable boundary layer forms after sunset and grows during the night, and that it is completely eroded by convection only after midday. On the other hand the mixing layer height, which is lower than the nocturnal planetary boundary layer, keeps nearly steady during the night, and then grows due to convection even on a cloudy day 1 Introduction
