[1] This is a study to quantify U.S. wind power at 80 m (the hub height of large wind turbines) and to investigate whether winds from a network of farms can provide a steady and reliable source of electric power. Data from 1327 surface stations and 87 soundings in the United States for the year 2000 were used. Several methods were tested to extrapolate 10-m wind measurements to 80 m. The most a...

The purpose of the study is to estimate the optimal release conditions for male and female world discus record holders of 1998 under no wind and in the wind. The estimation was achieved by using numerical methods to deal with the lift and drag coefficients in Ganslen’s wind tunnel tests of discus. The results showed that under no wind, when the release height of both male and female holders was...

The relationships of ranges to their respective standard deviations for wind direction and speed fluctuations are found for two urban locations at a height of 33 f t . above ground level. The standard deviations are computed from 1-, 5-, lo-, and 15-sec. average and 5-, lo-, and 15-sec. iiistantaiieous chart readings. The sampling intervals for which the standard deviations and ranges are compu...

Although numerical models are essential to hurricane forecasting, many other applications require only statistical depiction of the wind distribution. In Holland’s 1980 parametric profile, radius of maximum wind, maximum wind, and a measure of the profile width describe the radial variation of the axisymmetric wind. Variants of the Holland profile are used to predict insurance underwriting risk...

Conditional sampling is used herein to examine the e€ect of fetch, stability, and surface roughness changes on wind speeds in the coastal zone. Using data from an o€shore wind farm it is shown that at a distance of 1.2±1.7 km from the coast, up to a height of 20 m above the surface, di€erences in wind speed distributions from onshore and o€shore masts are statistically signi®cant for ̄ow moving...

Wind friction threshold speeds (V,t) for particle movement were determined in a low pressure boundary layer wind tunnel at an atmospheric pressure of 5.3 mb. The results imply that for comparable pressures on Mars, the minimum V,t is about 2.5 m/sec, which would require free-stream winds of 50 to 135 m/sec, depending on the character of the surface and the atmospheric conditions. The correspond...

Data of wind speed, wind direction and temperature obtained from a meteorological mast and a RASS sodar are contrasted. Wind data were compared at a height of 100 m and temperature at 51 and 100 m. 10 minute averages during the month of April 2001 were used. Wind speeds showed satisfactory correlation and the temperature fit was better at 100 m than at 51 m. Mast data were steadier than those f...

This paper tries to observe the site potentiality with respect to wind velocity for various height conditions in Bangladesh. From the analysis, it is seen that around 42.19% higher wind velocity is obtained in Cox’s bazaar than the wind velocity of Dhaka location for 50 m height.

Ship-based measurements of sea surface wind speed display a spurious upward trend due to increases in anemometer height. To correct this bias, the authors constructed a new sea surface wind dataset from ship observations of wind speed and wind wave height archived in the International Comprehensive Ocean– Atmosphere Data Set (ICOADS). The Waveand Anemometer-based Sea surface Wind (WASWind) data...
