Characteristics of Downslope Wind Storms in the View of the Typical Atmospheric Boundary Layer

Civil engineering infrastructure has been commonly designed according to relevant standards and codes — this is obligatory for the contractors and the owners. An important portion of those standards and codes focuses on wind- induced damage and structural collapse, whereas the wind characteristics are, for the most part, represented as the atmospheric boundary layer (ABL). At this moment, there are no clear guidelines or code implementations on the characteristics of local, mountainous wind storms. It is therefore of great interest to learn more about those winds and provide their characteristics in a form usable for engineers. The scope of the present chapter is to address characteristics of some major mountainous winds in comparison with the standard ABL, that is, Santa Ana (West Coast of North America), Foehn (European Alps), downslope winds of Liguria (Europe), Bora (Adriatic region in Europe), downslope winds of Japan (Asia), and Zonda (Andes in Latin America). The information presented is expected to enhance creating a platform for implementing the characteristics of local mountainous winds in the international standards and codes.
