Assessment of Temperature of Ramgarh District, Jharkhand, India: A Case Study of Coalfield’s Temperature

Abstract

Global interest in climate variability, especially annual temperature changes, necessitates an analysis of spatiotemporal meteorological dynamics, particularly in regions relying on rain-fed coal field agriculture areas. This study examines the impacts of temperature trends and climate change in Jharkhand's Ramgarh district, India. Six sub-divisions, such as Ramgarh, Gola, Chitarpur, Mandu, Patratu, and Dulmi, are under-examined, exploring long-term temperature changes from 1981 to 2022. Leveraging the Mann-Kendall test and Sen's slope Test, a 42-year data set analysis uncovers a decrease in average and maximum temperatures, contrasting an increasing minimum temperature trend. Applying Sen's slope for each temperature category Maximum, Minimum, and Average at Six sub-divisions of the Ramgarh district where Mandu has the highest increasing slope of 0.01 was observed in minimum temperature. However, Gola’s maximum and average temperature observed the highest decreasing slope among all stations. Similar patterns were found at other stations. Hence, our study suggests that additional attention should be given to the variability of temperature, and it is imperative to consider the increasing temperature trend to mitigate its effects on human well-being.
