1 INTRODUCTION Coastal fog has gained the interest of academics and researchers for over a century. A large effort has been made to study the life cycle of fog, that is, formation, evolution, and dissipation (Nakanishi, 2000), in coastal areas, addressing the physical, microphysical, and chemical processes related to its thermodynamics. Knowing the fog formation mechanism, we can make a first guess regarding the fog type (Gultepe et al., 2007) and evolution (Huang et al., 2015). Lewis et al.

Introduction Over mountainous terrain, under unperturbed synoptic-scale weather (i.e., anticyclonic conditions), the atmospheric boundary layer responds to the diurnal cycle of radiative forcing developing daily periodic wind systems at different spatial scales (Whiteman 2000; Giovannini et al. 2017; Lehner and Rotach 2018). These wind systems evolve during the day, variously interacting among them.
