Abstract: Rainfall variability has gained significant attention from the global research community, especially after the rising issues of climate change. In the present study, an assessment of the contributions of intensity-based rainfall classes (very low, low, medium, rather heavy, and heavy) to average annual rainfall as well as to the number of wet days over Tehri catchment, Uttarakhand, India, is presented. It is pertinent to mention that the very low rainfall class is not considered among wet days and hence is analyzed only for contributions to annual rainfall and not for contributions to the number of wet days. The daily rainfall data is collected for 119 years (1901–2019) from the IMD 0.25° × 0.25° grids, whose at least 25% fell within the boundary of the catchment. Fifteen grids are selected based on the above-mentioned criteria, and the period of 1901–2019 is divided into two parts, i.e., pre-1960 and post-1960 periods for a comparative assessment. The results reveal that the medium rainfall class contributes a majority of annual rainfall followed by light rainfall, rather heavy, heavy, and very low rainfall classes. Similarly, for wet days, medium (50%) and light (45%) classes are the major contributors followed by rather heavy (4%) and heavy (1%) classes. Regarding these contributions, no significant difference is observed between pre-1960 and post-1960 periods. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
