Turbulence Transitions and Advective Boundary Layers over the Sea
The behavior of this transition is examined in terms of wind direction which determines the fetch from the land with offshore flow directions. Low-level wind maxima above thin stable boundary layers are common with offshore flow of warmer air over cooler water. Such conditions also occur at this site with southerly flow from warmer water over the cooler water of the coastal zone. Because the stability is forced by advection, the boundary layer behaves differently compared to nocturnal stable boundary layers over land that are radiatively driven. These differences are explored. The characteristics of the drag coefficient and surface exchange coefficient for heat are interpreted in terms of these differences and the transition between the two scaling regimes.
