Structural Breaks in Mean Temperature over Agroclimatic Zones in India

Abstract EN

Amongst Asian countries India is one of the most vulnerable countries to climate change.

During the past century, surface temperature in India has shown a significant increasing trend.

In this paper, we have investigated behavior of mean monthly temperature during the period 1901–2001 over four agroclimatic zones of India and also tried to detect structural change in the temperature series.

A structural break in the series has been observed at the national as well regional levels between 1970 and 1980.

An analysis of trends before and after the structural break shows a significant increase in July temperature in the arid zone since 1972.
