Variation of Wind with Height

A Statistical Approach for Wave-Height Forecast Based on Spatiotemporal Variation of Surface Wind

Height variation of the solar granulation

We analyze spectral scans of narrow-band images across the Na D2 line. They were obtained from disc centre of the Sun with our Fabry-Perot interferometer (FPI) in the Vacuum Tower Telescope at the Observatorio del Teide. The FPI was set to a bandwidth of 200 mÅ FWHM and the spectral stepwidth was 100 mÅ. Our aim is to study the variation of the granulation pattern with height in the atmosphere....

Effect of Wind on the Rise Height of Volcanic Plumes

A theoretical model of a volcanic plume, based on applying the equations of motion in a plume-centered coordinate system, suggests that the interaction between a volcanic plume and wind causes enhanced entrainment of air and horizontal momentum, plume bending, and a decrease in plume rise height at constant eruption rate. Because of rapid dilution in the high windspeeds of the polar jet, plumes...

Optimization of the Hub Height of a Wind Turbine

This paper presents a new method for optimizing the hub height of a wind turbine. In general, wind turbine energy production increases with the hub height, but so does the cost. Therefore, we must optimize the hub height. Here, we calculated the annual energy production using a wind probability function. This is a function of the hub height and the roughness, which is a surface characteristic. ...

Height Analysis For Site Selection Of Wind Potentiality In Bangladesh

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.
