Temperature trend and variation analysis in the eastern plain zone of Uttar Pradesh

Abstract

The Eastern Plain Zone of Uttar Pradesh faces latent heat stress in the Rabi crop production. This study mainly concentrates on the minimum and maximum temperature data of the eastern plain zone. Data for the period 1981-2018 collected on a monthly and yearly basis to calculate trend and variation. Sen’s Slope Estimator and the Mann-Kendall (MK) test was used for pattern and slope magnitude determination. Maximum temperature decreased over the years for all the districts of Eastern Plain Zone (EPZ) whereas a significant increase in the minimum temperature was noticed. The majority of districts revealed a significant decrease in the maximum temperature in January, July and December months whereas minimum temperature significantly increased in February, April, May and October months.
