CLIMATE VARIABILITY IN DRY REGIONS OF INDIA: A CASE STUDY OF RAJASTHAN

R.B. SINGH, Ajay KUMAR

Abstract


The global community is in panic with fear of changing climate. Though it is very difficult to experience phenomenon of climate change but we can say that the climate is showing huge variability. To understand the impact of human on climate and vice-versa the knowledge of climate variability is necessary and moreover it helps in prediction of future trends of climate. In this paper spatio-temporal analysis of climate variation has been done by using interpolation technique.  About 61 per cent of total area of India has dry climate and its typical example is western part of Rajasthan. In the Western Rajasthan during last 30 years the temperature has shown a great variability with an average rise of about 0.5 oC for the month of June and 1oC for the month of January. During the same period the average annual rainfall has shown a decrease of 50 mm. With an overall rise in temperature over the region and changing precipitation trends the humidity provinces as defined by Thornthwaite, have shifted eastward. The climate variability studies can help to identify vulnerability of a region towards climate change which further helps in formulation of mitigation and adaptation strategies.
