Climatic variability in Jhansi region of Uttar Pradesh

Abstract

The daily rainfall and temperature data 1969-2000 of Jhansi were analyzed to know seasonal and annual variability. Three distinct crop growth seasons kharif (26-41 SMW), rabi (42-15 SMW) and summer (16-25 SMW) were characterized for seasonal trends. The stable rainfall period was worked out. The annual and kharif rainfall showed a decrease in rainfall in recent decade (1984-1993). Trend analysis on rainfall reflects a decrease of 0.89 and 1.12 mm per year in annual and kharif season during past 35 years whereas no such specific trend was observed for rabi and summer seasons. The temperature variability was small indicating only minor year-to-year variations. However, during recent decade, the minimum temperature showed an increase of 0.05 and 0.13 ° C per year during annual and kharif season.
