Statistical analysis of long term climatic data of Eastern Uttar Pradesh

Abstract

The study analyzes long-term climatic variability in Eastern Uttar Pradesh,
focusing on seasonal and annual variations in maximum and minimum
temperatures and rainfall across three agroclimatic zones: Eastern Plain, North
Eastern Plain, and Vindhyan Zone. Results indicate significant fluctuations,
particularly in post-monsoon and winter seasons, where higher coefficients of
variation were recorded for both temperatures and rainfall. Maximum temperature
variability ranged from 0.3% to 6.3%, while minimum temperature variability
reached up to 14.2%, especially in winter months. Annual rainfall also showed
considerable variation, with coefficients ranging from 0.1% to 43.8% across
zones and years. These climatic irregularities are likely to impact key crops like
rice and wheat, increasing vulnerability during critical growth stages. The
findings underline the urgency for adopting climate-resilient agricultural
practices, improved irrigation management, and region-specific crop planning.
Addressing this rising agroclimatic instability is essential to ensure sustainable
agricultural productivity and food security in Eastern Uttar Pradesh.
