Trend Detection of Temperature, Diurnal Temperature Range and Rainfall in Amritsar by using Mann Kendall Test
Year: 2025
Type: article
Abstract: The analysis of diurnal temperature range (DTR) for Amritsar from 1970-2023 was done.Daily minimum and maximum temperature were analyzed for additional consideration of DTR trend by using time series.DTR change of the Amritsar and seasonal variations of maximum and minimum temperature, rainfall by separating into and season.Diurnal temperature range (DTR) Rabi Kharif steadily decreased at the rate of -0.042°C/yr, -0.033°C/yr and -0.046°C/yr during annual, and season in the past 50 years.The Kharif Rabi yearly maximum averaged temperature indicated marginal decreasing trend but the yearly mean least temperature is increasing more rapidly, 0.028 °C/yr, 0.029 °C/yr and 0.028 °C/yr during annual, and season.The significantly expanding pattern of mean least temperature Kharif Rabi adds to the reduction of mean DTR.Annual and total rainfall has decreasing trend at the rate of -0.039 mm/yr and -0.223 mm/yr but the Kharif total rainfall during showed slightly increasing trend with 0.026 mm/yr.
