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☄2'52"N and longitude of 78☂7'29"E) VV Reddy Nagar, Kadapa, and Andhra Pradesh, India.

Effect of meteorological conditions on the air quality of delhi to tackle the problems and to reduce health risks generated due to air pollution, immediate steps need to be taken. Wind Rose diagrams represent the two - way joint frequency distribution of wind direction and any parameter under consideration. Monthly wind rose diagrams generated for rtpp, kadapa station, a.p, india, from june 2011 to may 2012 are shown below Wind rose module (using raw wind data). hence, it is necessary to know the processes in different scales based on meteorological aspects. Description of Sun path Diagram The heavy lines running from east to west represent path of sun on 21st day of each month of the year.

Wind data from 2009 onwards was used to generate the plots. The site shows a frequency distribution over 16 directions and 7 wind speed ranges, and plots the results graphically as a wind rose diagram. Air pollution processes vary in time and space according to their transport, dispersion, removal, transportation etc. Description of Wind Rose Wind rose gives detailed information on wind speed and direction for a month or a whole year. Windrose plots for about 80 Indian cities (as of 2010). In addition, it is necessary to know the trends in air quality so that control efforts can be regulated accordingly. There is paramount need to protect man, domestic animals, crops and materials from damaging exposure to air pollution. Thus the wind rose is a simple information display technique that has a multitude of uses.An air quality management program requires reliable information on air quality to be collected, analyzed and evaluated. Windpower "farms" do extensive wind rose type studies prior to erecting their wind turbines. If wind rose data had been collected and used prior to the construction of San Francisco's famous windy Candlestick Park, the stadium could have been placed a few hundred yards to the north where it would have been protected from the prevailing westerly wind. Architects do, or should, use wind rose information for the siting of buildings and stadiums. Naval Oceanographic Office to get average winds for each ocean for each month of the year to help the create optimal sailing routes between ports. Sailors use wind rose information taken from the "Pilot Charts" by the U.S. The information provided by the wind rose can be applied to many and varied situations. A good example of a wind rose application is shown at the following URL. Wind speed data can be superimposed on each direction segment to indicate, for example, the average wind speed when the wind was blowing from that segment's direction and the maximum wind speed during the logging period. Typically the wind direction data is sorted into twelve equal arc segments, 30° each segment, in preparation for plotting a circular graph in which the radius of each of the twelve segments represents the percentage of time that the wind blew from each of the twelve 30° direction segments. The collected wind data is then sorted by wind direction so that the percentage of time that the wind was blowing from each direction can be determined. It also returns the data represented in the graph into a data table (double array and cell array that can be directly exported to excel). An interective web-page on the state wise seasonal mixing height data for India has been added. To create a wind rose, average wind direction and wind speed values are logged at a site, at short intervals, over a period of time, e.g. For observing stations where wind speeds are measured, mostly at airports, users can access tabular data and / or generate wind rose plots. The wind rose is the time honored method of graphically presenting the wind conditions, direction and speed, over a period of time at a specific location.
