Due to the random, intermittent, and volatile nature of wind speed, in order to accurately describe the wind speed characteristics, in this paper, the wind speed's mathematical model was created using a combination of four components that are basic wind, gust wind, gradient wind and noise wind.
Gradient wind describes a wind field's steady energy that is changing slowly over time; it can be expressed as a superposition of a gradient component and the basic wind speed
Notice that in fine vortical structures, where the centrifugal force becomes important, the gradient wind
balance (between pressure gradient, Coriolis and centrifugal forces) could advantageously replace the geostrophic balance for constraining slow modes.
One of the tough things to work out at this part is the transition between the sea breezes and the gradient wind
Examples of specific topics covered include aircraft electrification, airmass, anabatic wind, boundary layer, convection, Dansgaard-Oeschger event, Dobson spectrophotometer, gradient wind
, katabatic wind, meteorology, noble gases, pollution control, temperature scales, waterspout, and Venturi effect.
As long as the gradient wind does not exceed 23 knots, we would normally expect the morning NW wind to decrease and a SE sea breeze to develop over the Derwent around noon, local summer time.
In S to SE gradient wind situations, winds over Storm Bay and the Derwent are generally more uniform, although some acceleration can be expected near the more prominent points and headlands.
ii) Under any kind of offshore gradient wind flow, Storm Bay is affected by the significant topographic features of southern Tasmania and can be most frustrating.
With west gradient winds, the entire coast generally suffers from the effects of the lee trough.
