Hydrogeological multiple hazard: a characterisation based on the use of historical data
Published in Jan Rybář, Josef Stemberk, Peter Wagner, Landslides, 2018
In the summer (northern hemisphere) the Azores high strengthens, builds northwards and tends to dominate north Africa and the southern Mediterranean. This produces the typical Mediterranean summer of clear, hot and still conditions. Any rainfall, there is, tends to be due to convective activity in the fairly moist air over or near the sea (Barry & Chorley 1987).

Azores High: The Azores High is a high-pressure pattern that forms in the subtropical Atlantic Ocean. Although it occurs outside the Arctic Ocean, it is linked to the Icelandic Low through the North Atlantic oscillation.

The North Atlantic Oscillation (NAO), mainly mediate the weather conditions in the NWCIP. The Azores High induces northerly and north-westerly (NW) winds over the area that are prevalent throughout the year, with the highest magnitudes in the summer season (Ramos et al. 2011). As a result, dominant NW waves are produced with a mean Hs of 2m and a peak period between 9 and 13s (Costa and Esteves 2008). During winter, low-pressure systems generated over the Atlantic can cross the NWCIP with associated south-westerly (SW) and south (S) winds, producing extremely high energetic conditions on the continental shelf (Vitorino et al. 2002a). Hs between 3 and 6m are not uncommon, reaching between 9 and 12m during strong storm events (Dias et al. 2002; Vitorino et al. 2002a, 2002b; Costa and Esteves 2008).
