The study of meteorological parameters like rainfall and temperature characteristics changes are critical for agricultural, environmental and water resources projects. Generally, trend analysis is performed to evaluate the direction and magnitude of changes in meteorological variables. In this study, the trends in rainfall and temperature and the possible relation between them have been investigated at four stations of Jaraikela catchment of Brahmani river basin in annual, monthly and seasonal time steps. The annual rainfall and temperature show an increasing trend at all stations. As far as monthly analysis is concerned, no definite pattern has been observed in maximum and minimum temperature and rainfall. This study revealed that there exists no direct relationship between increasing rainfall and increasing maximum temperature when the monthly or seasonal pattern is concerned over meteorological subdivisions of the catchment; however, it is concluded that the relations between the trends of rainfall and temperature have large scale spatial and temporal dependence.
