Abstract | The temperature in the mountains has been increasing at an unprecedented rate in the global warming era. As a result, it is necessary to evaluate suitable models that could provide precise maximum temperature estimates. This paper explores the goodness-of-fit of the two-parameter bell-shaped, light-tailed, and heavy-tailed distribution functions for modeling the annual maximum temperature in the Northwest Himalayan region of India. The distributions under consideration are Gamma, Gumbel, Lognormal, Normal, and Weibull. Method of maximum likelihood estimation is used for parameter estimation along with Akaike information criteria for model selection. Gridded data from Climate Research Unit, UK, was obtained at the 525 grids of the region. This study shows that Normal distribution gives the best fit followed by Lognormal and Gamma distributions, and these three models jointly fit all the grids in the region. Furthermore, we estimate the 5, 10, 20, 50, 100, and 500 years return level of annual maximum temperature starting from 2017. The future projections reveal that, on average, the region will face [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] temperature rise by the years 2022, 2027, 2037, 2067, 2117, and 2517, respectively. In comparison to the middle of the region, the higher and lower belts of the region will be severely impacted. |
