Climate Change, Heat Wave, temperature rise, relative humidity
Globally, the temperature with its devastating impacts is increasing day by day. This rising temperature for prolonged periods leads to heat wave formation, which is exacerbating due to the increasing climate change. The change in frequency, duration and magnitude of temperature and relative humidity are the manifestations of climate change. Heat wave refers to the degree to which the increased temperature with relative humidity varies and increases vulnerabilities of communities towards climate change. Heat waves affects specifically human health besides other development activities. This study focuses on the heat wave trend analysis associated with the variability in temperature and relative humidity in Delhi for the time period of 61 years (1955-2015). The data is analyzed for the months April, May and June using liner square method. The significance of the trend is analyzed with the help of t-test. The heat wave shows an increasing trend for all three months for the selected period. Through the analysis, it is projected that there may be an increase in heat wave, which might further influence and augment the vulnerability of the communities towards climate change and other development activities.
