Global Warming, maximum temperature, rainfall, linear trend, Mann-Kendall testAbstract
The temperature and rainfall trends are analyzed for meteorological data of Anand in Gujarat, India over approximately last three decades stretching between years 1980 to 2011. The long–term change in temperature and rainfall has been assessed by linear trend analysis. The increasing trend in mean of maximum (MMAX) temperature and total mean rainfall (TMRF) is confirmed by Mann-Kendall trend test. It is observed that in Anand of Gujarat, the monthly mean of maximum (MMAX) temperatures have increased significantly for all the months except the month of October for which a very weak decrease in MMAX temperature is observed. This implies that in Anand the highest decrease in MMAX temperature occurs in December (0.0580C). The annual mean of monthly mean of maximum temperatures observed an increasing trend having an annual increase of 0.0060C per year and monthly mean of TMRF have increased significantly for the months March, April May, June, July, August, September, and October whereas it shows decreasing trend in January, February, November, and December for the Anand. This implies that in Anand, the highest increase in TMRF occurs in October and has increased by 4.983 mm during the last 32 years. The annual mean of monthly mean of total mean rainfall observed an increasing trend having an increase of 0.063 mm per year.
