Data from an international collaborative study are used to illustrate the application of this proposed interpretation of the coefficient of variation, and they also provide support for the assumptions used in the mathematical derivation. Tamil Nadu is classified into seven agroclimatic zones: northeast, northwest, west, southern, high rainfall, high altitude hilly, and Cauvery Delta (the most fertile agricultural zone). Over land regions of Asia, the projected area-averaged annual mean warming is likely to be 1.6 ± 0.2°C in the 2020s, 3.1 ± 0.3°C in the 2050s, and 4.6 ± 0.4°C in the 2080s and the models show high uncertainty in projections of future winter and summer precipitation. Despite a growth in productivity Annual and seasonal maximum and minimum temperatures are predicted to have more variability and significant warming trend in the future.
