WebThe surface roughness length for a given location over land is generally specified to be constant depending on the terrain condition, whereas the roughness length over the sea can be highly variant, which depends strongly on the time-dependent air-sea momentum transfer via the wind-driven surface wave field [ 18, 19 ]. WebFor the characterization of MABL, the assessment of sea-surface roughness has re-ceived much attention [4,11–16]. For example, Anctil and Donelan [2] focused on the effect of shoaling waves (i.e., wave steepness and celerity) on the aerodynamic roughness of the water surface. Essentially, sea-surface roughness is one of the key parameters for

WebThe roughness length is commonly parameterized using the roughness Reynolds number for smooth flow to provide the surface “roughness” at low winds (Smith, 1988). Other low … The Douglas sea scale, also called the "international sea and swell scale", was devised in 1921 by Captain H.P. Douglas, who later became vice admiral Sir Percy Douglas and hydrographer of the Royal Navy. Its purpose is to estimate the roughness of the sea for navigation. The scale has two codes: one code is for estimating the sea state, the other code is for describing the swell of the sea. Web16 Dec 2024 · The control experiment calculates the sea-surface roughness length as a function of friction velocity based on the Charnock relationship. The experiment considering water depth in the sea-surface roughness length over shallow waters is compared with the control experiment. capricorn kontakt
