Variability and Long-Term Changes in Surface Air Temperatures Over the Indian Subcontinent

Surface air temperature is one of the most important meteorological parameters of the climate system. It is widely used to detect the first signal of climate change. The term, “global warming,” frequently discussed today, is a consequence of the substantial rise in surface temperatures across the globe. With the steep rise in surface temperatures over the past few decades, global warming is being viewed as a triggering source of the observed and projected rise in the frequency and intensity of many extreme weather events. Owing to this observed and projected temperature rise, climate models indicate larger changes in the climate system, on regional and planetary scales. Probable changes in the climate systems affecting the Indian subcontinent, due to rise in regional surface temperatures, are of great concern. Changes in seasonal temperatures over the region, especially trends in temperature gradients, may induce a significant change in monsoon performance and its effect on crop production. Hence, it is desirable that a true assessment of the rise in the surface temperatures over the Indian subcontinent is carried out. In this chapter, we document the past observed changes in surface air temperatures over the region as a whole and on different parts of the region. The analysis has been done for (a) for the whole data period 1901-2010 and (b) recent 30 years 1981-2010.
