Evolution of Wind Rose Diagrams for RTPP, KADAPA, A.P., India

An air quality management program requires reliable information on air quality to be collected, analyzed and evaluated. There is paramount need to protect man, domestic animals, crops and materials from damaging exposure to air pollution. In addition, it is necessary to know the trends in air quality so that control efforts can be regulated accordingly. Air pollution processes vary in time and space according to their transport, dispersion, removal, transportation etc. hence, it is necessary to know the processes in different scales based on meteorological aspects. Wind Rose diagrams represent the two - way joint frequency distribution of wind direction and any parameter under consideration.

This paper presents the evolution of wind rose diagrams for various environmental applications and to understand the distribution pattern of air pollutants emitted from Rayalaseema Thermal Power Project (latitude of 14°42'52"N   and longitude of 78°27'29"E) VV Reddy Nagar, Kadapa, and Andhra Pradesh, India.
