Sir Francis Beaufort. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded ...
Wind stress in one of the drivers of the large-scale ocean circulation with other drivers being the gravitational pull exerted by the Moon and Sun, differences in atmospheric pressure at sea level and convection resulting from atmospheric cooling and evaporation. However, the contribution of the wind stress to the forcing of the oceanic general ...
This is followed by gale warnings (winds of force 8 or more on the Beaufort scale), if any (e.g., "There are warnings of gales in Rockall, Malin, Hebrides, Bailey, and Fair Isle"). This sometimes follows the opposite format (e.g., "There are warnings of gales in all areas except Biscay, Trafalgar and FitzRoy").
Historically, the Beaufort wind force scale, created by Francis Beaufort, provides an empirical description of wind speed based on observed sea conditions. Originally it was a 13-level scale (0–12), but during the 1940s, the scale was expanded to 18 levels (0–17). [21]
Gale warning flags (USA) A gale warning is an alert issued by national weather forecasting agencies around the world in an event that maritime locations currently or imminently experiencing winds of gale force on the Beaufort scale. [1]
Severe local storms – Short-fused, small-scale hazardous weather or hydrologic events produced by thunderstorms (including large hail, damaging winds, tornadoes, and flash floods). Winter storms – Weather hazards associated with freezing or frozen precipitation ( freezing rain , sleet , and/or snow ), or combined effects of winter ...
The scale doesn’t prescribe a right and a wrong way to eat, Van Eck says, but if you’re able to identify where you fall on it, you can get insight into how much to eat and when, and even avoid ...
For initial conditions of a flat water surface (Beaufort Scale 0) and abrupt crosswind flows on the surface of the water, the generation of surface wind waves can be explained by two mechanisms, which are initiated by normal pressure fluctuations of turbulent winds and parallel wind shear flows.
