The approach uses static pushover analysis of OWT support structures subject to wind and wave combined load patterns corresponding to increasing mean return period (MRP).
An increase in altitude in inland areas generally increases the mean wind speed; similar wind speeds are recorded on the highest parts of Exmoor and Dartmoor as on the coast.
Standing residue with the heights of 30-, 40- and 50-cm increased mean aerodynamic roughness length (equivalent to the height at which the wind speed theoretically becomes zero) by 19.87, 43.77 and 61.62, respectively, and increased mean threshold wind speed by 11, 25 and 33%, respectively.
The turbulence intensity is shown to have a small stabilizing effect on the bridge stability in a sense that an increase in the turbulence intensity moderately increases the critical mean wind velocity beyond the deterministic flutter velocity.
Certainly, and providing that the Taylor's hypothesis of frozen turbulence [17, 18] is satisfied, that increase in the mean wind speed transverse to the propagation path will not affect the bit error rate since this one is a first-order statistic; but a figure of merit expressed in terms of burst error rate will be completely affected.
The size of the temperature ramps is expected to increase as the gradients in mean wind speed and mean temperature increase, and it follows that if insects do use temperature ramps as orientation cues then the mean gradient in these two variables should be accompanied by an increase in the 'tightness' of orientation (i.e. a decrease in angular dispersion around the mean value).
The mean wind speed is increased and decreased, respectively, in unstable and stable conditions.
In urban environments however, the wind resource has lower mean wind speeds and increased levels of atmospheric turbulence due to heterogeneous surface forms.
The available average power in the wind flowing through a rotor blade with swept area, A (m2) is known to increase as the cube of its mean wind speed, vm as: P v = 1 2 ρA v m 3. Open image in new window (7).
Results show that turbulence intensities decrease as the mean wind speed increases, except in the area with the superposition of general winds and typhoons.
