Climate change and the precipitation variations in the northwestern Himalaya: 1866–2006
Abstract Using available instrumental records, this paper examines the variation of precipitation from 1866 to 2006 in the northwestern Himalaya (NWH). The study indicates no trend in the winter precipitation but significant decreasing trend in the monsoon precipitation during the study period. Peri...
