IV. D iscussion After the individual interpretation of data, needs to be done overall correlation of studied data to predict the future climatic condition. For best correlation of data, we should find out the percentage variation from last time decades. Stepwise data have given below: The Year Mean radiation for Ist half-year (W/m2) Mean radiation for IInd half-year (W/m2) Mean yearly radiation in (W/m2) Percentage variation from last decade Ist half year Percentage variation from last decade IInd half year Percentage variation from last decade (yearly) 1988-1997 6244.65 4561.15 5402.90 1998- 2007 6237.14 4833.11 5535.12 -0.120 5.962 2.447 2008-2019 6227.02 4454.78 5340.90 -0.162 -7.828 -3.509 The Year Mean Pressure for Ist half-year (in hPa) Mean Pressure for IInd half- year(in hPa) Mean Pressure (in hPa) Percentage variation from last decade Ist half-year Percentage variation from last decade IInd half-year Percentage variation from last decade (yearly) 1988-1997 1007.34 1007.45 1007.40 1998- 2007 1007.53 1007.53 1007.53 0.019 0.008 0.013 2008-2019 1007.69 1008.43 1008.06 0.016 0.089 0.053 Table 13: Kota atmospheric pressure percentage variation from last decades Items 1978-1987 1988-1997 1998-2007 2008-2019 The Yearly Ist half IInd half The Yearly Ist half IInd half The Yearly Ist half IInd half The Yearly Ist half IInd half MWD NW NW NE W NW W W N SW WSW W WSW HWES 0-5 0-5 0-5 0-5 0-5 0-5 0-5 0-5 0-5 5--10 5--10 0-5 HWES: Highest Wind Event Speed Table 14: Maximum observed wind event direction with speed the yearly, Ist half and IInd half-yearly The Year Average Precipitation for Ist half-year Average Precipitation for IInd half-year Average yearly Precipitation (in mm) Percentage variation from last decade Ist half-year Percentage variation from last decade IInd half-year Percentage variation from last decade (yearly) 1978-1987 104.67 608.50 713.17 1988-1997 114.88 715.82 830.70 9.75 17.64 16.48 1998-2007 108.29 443.31 551.60 -5.74 -38.07 -33.60 2008-2019 102.69 510.68 613.38 -5.17 15.20 11.20 Table 15: Kota precipitation percentage variation from last decades © 2021 Global Journals 1 Global Journal of Science Frontier Research Volume XXI Issue VI Year 2021 18 ( H ) Version I Role of Solar & Atmospheric Disparity on Climate of Western India, Kota, Rajasthan, India Table 12: Kota Solar Radiation percentage variation from last decades
