Wind setup, also known as wind effect or storm effect, refers to the rise in water level in seas, lakes, or other large bodies of water caused by winds pushing the water in a specific direction. As the wind moves across the water’s surface, it applies shear stress to the water, generating a wind-driven current.
The interchangeability of pressure and wind allows for the two to be used to give equivalencies for the public. [7] Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [6] Some storms may have particularly high or low pressures that do not match with their wind speed.
Flow visualization of wind speed contours around a house Wind engineering covers the aerodynamic effects of buildings Damaged wind turbines due to hurricane Maria. Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage ...
Incidentally, due to this phenomenon, a small reduction in water level occurs just seaward of the breaker line, in the order of 20% of the wave set-up. The wave setup at ocean beaches can be significant. For example, a wave with a height of 5 m (on deep water) and a period of 12 s, at perpendicular incidence and γ = 0.7, gives a wave setup of ...

The portal was founded by Ivo Lukačovič in November 2014, [1] [2] initially focusing on wind animation. It has since expanded to include various essential meteorological parameters, such as temperature, pressure, relative humidity, cloud base, and additional panels featuring more advanced data.
The driving force behind the vertical velocity is the Ekman transport, which in the Northern (Southern) hemisphere is to the right (left) of the wind stress; thus a stress field with a positive (negative) curl leads to Ekman divergence (convergence), and water must rise from beneath to replace the old Ekman layer water.
