Assessment of Reference Evapotranspiration in the Context of Climate Change for Central India (Madhya Pradesh)

Abstract

In this article, trend detection of reference evapotranspiration (RETo) was investigated for Madhya Pradesh State, Central India. There were 45 stations selected for the study, and analysis was carried out for 102-year duration (1900–2002). Trend of the RETo was detected based on the monthly, seasonally and annually applying nonparametric Mann–Kendall (MK) tests at the 5% and 1% significant level. The same tool was also applied on the other climatic variables (Tmax, Tmin, cloud cover and vapor pressure) to observe the reason of existence of such trend in RETo.
