Abstract: Precipitation and temperature, being the fundamental variables of climate, need to be studied extensively to understand the hydrological response of any watershed. This research aims to investigate the spatio-temporal variability of a data-sparse Himalayan watershed. The spatial patterns of the two variables are analysed at various time scales. The Mann-Kendall (MK) test is employed to detect the trends for both precipitation and temperature at different time scales. The results suggest that the spatial patterns of precipitation are affected by the orographic effects, and those of temperature are affected by the elevation changes in the study area. The trend analysis results point towards increasing trends in both temperature and precipitation on the annual time scale, which could result in glacier melting, lesser snowfall, and extreme events in the future. The study will prove fruitful in better understanding the area's hydrology, mainly because it is a data-sparse region. Also, it can assist in carrying out rainfall-runoff hydrological modelling more efficiently.

Keywords: precipitation; temperature; spatio-temporal; spatial patterns; trend analysis.
