Abstract

The rainfall and temperature is the most fundamental physical parameter among the climate as it determines the environmental factors of the particular region which affect the agricultural productivity. Global warming/climate change is one of the most important worldwide issue talked among the scientists and researchers. Attempts have been made to study the temporal variations and trends in monthly, seasonal and annual temperature over Anand (middle Gujarat). Analysis has been carried for four temperature indices, namely - minimum temperature (Tmin), maximum temperature (Tmax), mean temperature (Tmean) and diurnal temperature range (DTR). Non-parametric Mann-Kendall (MK) test was used to detect the trends and the magnitude of the trends were determined with Sen’s estimator of slope.The present study is the warming trends in Tmin , Tmax and Tmean temperatures and decreasing trends in DTR over City of Anand. At the site, the total numbers of statistically significant values in three temperature indices - Tmin , Tmax and Tmean are more than total numbers of non-significant values on annual, seasonal and monthly timescale.All the trend in Tmin variable are increasing at the station on annual, seasonal and monthly scale. These increasing trends in Tmin are significant at annual, seasonal and monthly scales over January, July August and December over Anand, it is significant at annual, seasonal (winter, monsoon, post-monsoon). In general, the magnitudes of rate of change in Tmin are higher as compared to other variables on all time scale at the station.The increasing trends in Tmax at Anand are significant on annual scale, monsoon season as well as in February, March, May,June, August, October to December at Anand Similar to the trends observed in Tmin and Tmax, Tmean shows significant increasing trends on annual, seasonal (monsoon and post-monsoon) and monthly (except January) scale over Anand timescale. DTR shows significant decreasing trends on annual scale, winter season, post-monsoon season and in April month at Anand.
