for the last 50 years (1961-2010) were used. The daily maximum temperature data for
the period 1969-2010 were obtained from National Data Center, India Meteorological
Department, Pune and data for the period 1961-1968 were derived from daily Indian
Daily Weather Report logs published by India Meteorological Department.
It was observed that the stations from the northwest Rajasthan and neighboring
Punjab, north M. P and coastal Andhra Pradesh experienced more than 700 days of heat
wave days during the data period 1961-2010. Also stations from Uttaranchal, east Uttar
Pradesh, Bihar, and Orissa experienced more than 60 severe heat wave days during the
data period of 1961 – 2010. Among the 104 stations used here, Nellore has experienced
maximum number of heat wave days (1646) during the entire period followed by
Ganganagar (830), Chennai (781) and Jhansi (769). Ganganagar, Hissar, Bhubaneswar
showed consistently increasing trend of heat wave across all the decades. In the case of
severe heat wave days, Dehradun experienced the maximum number of severe heat
wave days (82), followed by Bahraich (64), Purnea (63) and Balasore (62). The
maximum number of heat wave days was observed in the month of May and maximum
number of severe heat wave days was observed in the month of June. The decade 2001-
2010 experienced the maximum heat wave spells. The year 2010 had the maximum
number of both heat wave and severe heat wave days. There is a significant increase in
the spatial coverage of heat wave and severe heat wave during the decade 2001 – 2010
compared to the previous decade.
The results of trend analysis show evidence of an increasing trend in heat wave
days over India during 1961-2010 with more than 50% stations showing statistically
significant increasing trend.
It can be concluded that the observed increasing trend in the heat waves in India is
in tune with the observed global warming.
