dc.description.abstract | This study examined trends and change points in long-term annual and seasonal rainfall over hot- and cold-arid regions of India. K-means clustering classified 32 stations into two clusters Coefficient of variation for annual, wet season and dry season rainfall ranged from 19-41%, 22-43% and 30-55%, respectively for Cluster-I and from 25-47%, 31-52%, and 43-142%, respectively for Cluster-II. Short- and long-term persistence was more dominating in Cluster-II (entirely-arid) and Cluster-I (partly-arid), respectively. Sen’s method revealed increasing trends for annual and wet season from 0.92-1.35 and 0.77-0.85 mm-year-1 for Cluster-II, and from 0.93-1.21 and 0.81-1.13 mm-year-1 for Cluster-I, respectively. Dry season rainfall increased with 1.09 mm-year-1 in cold-arid region. The significant change points in annual and wet season rainfall mostly occurred during 1941-1955 (hot and cold), and in dry season during 1973-1975 (hot-arid) and 1949 (cold-arid). Moreover, the findings are useful for managing surplus/deficiency of rainwater in the Indian arid region. | en_US |
