Climate Analysis and Trends Assessment

Raju Kalita from the Department of Physics at Northeastern Hill University presents a trend analysis of climate indices for daily temperature and precipitation records in Tura, Meghalaya. The study uses data from NASA's Langley Research Center, covering the period from 1982 to 2019. The analysis involves 27 core climate indices, with a focus on temperature and precipitation. The Mann-Kendall test is applied to determine trends, revealing significant findings in temperature and precipitation patterns. The study concludes with insights into the impact of climate change on the region, highlighting a decrease in cold nights and an increase in precipitation intensity.
