A Study Of Temperature And Rainfall Trends In Buldana District Of Vidarbha, India

[Full Text]



D. T. Deshmukh, H. S. Lunge



Keywords: - Global Warming, maximum temperature, rainfall, linear trend, Mann-Kendall test.



Abstract: - The temperature and rainfall trends are analysed for meteorological data of Buldana district in Vidarbha, India over approximately last three decades stretching between years 1975 to 2005. 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 Buldana district of Vidarbha region, the December MMAX temperature has increased by 2.69390C and annual MMAX temperature has increased by 1.32060C whereas the highest decrease in TMRF occurs in November, by 25.079 mm, and annual TMRF has increased by 12.137mm, during the last 31 years. Annual MMAX temperature shows increasing trend which is statistically significant at 5% level of significance whereas annual TMRF shows increasing trend which is statistically insignificant at 5% level of significance.
