The Nocturnal or Night Low-Level Jets (NLLJ) are those jets that have their maximum intensity at night and are formed by the decoupling of the PBL. The aim of this study is the detection of NLLJ using an objective methodology (Rife et al., 2010). To do it, an index based in the vertical structure of the wind’s temporal variation was used. Once identified, we investigated its structure, the vertical profile, and its temporal evolution.
