Characterisation of the Nocturnal Boundary Layer at a Site in Northern Spain

摘要

The availability of well-calibrated meteorological data for a 10-month period on a 100-m tower has allowed a statistical study to be carried out of many boundary-layer variables. The analyses are restricted to nighttime conditions with stable stratification most of the time, allowing the checking of a number of similarity proposals and the quantifying of the frequency of the different nighttime regimes. We study in detail two typical nights at the site: one weakly stable and one with very strong stratification, highlighting the different aspects between the nights.
