The results were compelling: the mean wind
speed absolute error observed between the SLD and the met mast reference was less than 0.
New planning rules introduced by central government mean wind
farms should only get the go-ahead if clearly backed by local people.
GUSTS "There will be a constant, mean wind
of 45 to 55kmh but short-term gusts will reach 80 to 100kmh.
The Met Office and TORRO (The Tornado and Storm Research Organisation) estimated that the tornado had a general 'T4' rating on the TORRO scale with a short spell as a 'T5' tornado, which would mean wind
speeds between 93 and 130 mph, equivalent to an F2 on the Fujita scale.
Tatge concluded, "Gust wind speeds compared to mean wind
speeds were unusually high and compare to values for Kyrill in 2007.
The hub height is generally cost-optimised for each specific site taking account three things: The increase of mean wind
speeds with height and therefore energy production of the turbine with higher towers; Increased cost of higher towers and consequential increase in foundation costs; External constraints, e.
1 show the Weilbull distribution, described by its probability function, versus the mean wind
speed, for data collected on an annual basis from 1995 to 2005, for the city of Annaba--Algeria, based on parameters calculated using the Weibull methods presented in previous section.

To obtain a relatively meaningful wind speed figure an anemometer would necessitate being on site for at least two years so as to measure local wind speeds, then a mean wind
speed figure would need to be identified so as to extrapolate a guestimated annual generation figure.
A storm is defined as an event when a 10-min mean wind
speed [greater than or equal to] 15 m [s.
Surely, those idiots on the council can work out that "Outstanding Beauty" in AONB doesn''t mean wind
The changes in the monthly mean wind
speed are less coherent.
