Abstract
The research is aimed at obtaining information about wind turbulence in urban environments for the development and installation of renewable energy technologies, based on data collected by two propane anemometers, near the ledge of the INTEC Building AH, The data presented correspond to measurements between the month of May 2017 to January 2020.
The data processing allowed to know that the behavior of the average wind speed at both measurement points is similar throughout the period. Wind roses show that in the location of the lowest height anemometer, the wind direction is more stable as these records have smaller dispersions. The hourly wind analysis corresponds to a site near the coast, where the speed rises rapidly at dawn reaching maximum values at noon, from there a plateau is seen, while the night speeds are discrete in all months, the highest values being at August and December.
Weibull velocity distributions for both anemometers, using factors, of form k = 2 and of scale c = 2,80 with average speed 2.48 m/s, it is appreciable greater accumulation of low velocities (range 1-3 m / s) in anemometer # 1, while for # 2 (higher) there is greater accumulation in the range of 3-7 m/s, while for speeds greater than 7 m/ s the accumulated have no appreciable differences.
