In the context of climate change and its impact on sectors like agriculture and health, it is important to examine the changes in the characteristics of temperature extremes of different intensities and duration. In this study, an India Meteorological Department gridded temperature dataset is used to examine the changes in the frequency of occurrence of extreme temperatures over India and its seven homogeneous regions during the period 1969–2005.

Heat stress is an important aspect in the lives of people working under exposed conditions for long hours. It is interesting to examine the impact of global warming on the occurrence of heat stress in India. This study uses India Meteorological Department (IMD) daily temperature gridded data to
investigate the changes in frequency and episodes of extreme temperature events in seven temperature homogenous regions and the country as a whole by applying the guidelines suggested by the World Meteorological Organization ‘Expert Team on Climate Change Detection and Indices’. It is

To examine changes in the wintertime seasonal (December, January and February) temperature and precipitation over the Siachen Glacier, one of the largest glaciers outside the polar region, an analysis of its temperature and precipitation indices is planned.

In this article meteorological measurements in India are analysed showing marked trends of increasing temperature over the past quarter century, but significant variations in these trends during different seasons and over different regions of India. Marked differences between the variations in minimum temperatures in North and South India have been brought out.
