Sentence examples for frequency of winds from inspiring English sources

Wind rose diagrams depict the frequency of winds blowing 'from' a particular direction over the 64-year period.

Presented in a polar coordinate grid, the wind rose shows the frequency of winds blowing from particular directions.

Sources located in other directions from the monitoring site had less influence despite greater emissions and a high frequency of winds.

The frequency of wind speed observed that Weibull distribution gave better fitting results than Rayleigh distribution at wind site.

Analyses of the frequency of wind directions indicate that variations in the large-scale wind climate occurred at that time.

The new wind probability distribution map integrates both frequency of wind speed and direction data at a monitoring site.

Then, on the basis of a Weibull distribution, the cumulative frequency of wind velocities between cut-in and cut-out limits of the turbine is calculated (Table5).

For a single site, the frequency of wind speeds is usually analyzed with methods like the extreme value theory (EVT), which is based on historical ground meteorological observations (Elsner et al. 2008).

The study calculated the ventilation resistance coefficient of building height according to fluid mechanics, and then determined the least cost path among the air inlets and outlets considering the direction and frequency of wind.

The results suggest that urban design based on urban morphology and building height and considering the direction and frequency of wind would be effective for optimizing ventilation to regulate urban environmental problems.
