Software Proposal for Determining the Prevailing Wind Direction: PrevailingWindRUB 1.0

Abstract

Knowing the characteristics of the climatic elements of a place is greatly important in spatial studies. Although not used as often as temperature and precipitation, wind might be utilized as a guide especially in planning studies. Wind is mostly a horizontal movement. The direction, speed and frequency of the wind are its three most prominent characteristics. Establishing the prevailing wind direction in terms of angle will provide more realistic results. Rubinstein stated that the prevailing wind direction can be determined in degrees based on how often the wind blows from which direction. The ratio of the directions from which the wind blows to all directions is used in the proposed method. While doing so, considering certain relations with the shares belonging to different directions at the same time makes this method more advantageous over others. The method does not use data on calm days, but shows the second-order prevailing wind direction and frequency if available. The software attached used herein is proposed to determine the prevailing wind direction using the Rubinstein method.
