Changes in rainfall and relative humidity in river basins in northwest and central India.

The article focuses on the changes in rainfall and relative humidity in river basins in northwest and central India. It shows that most of river basins have increasing trends both in yearly rainfalls and relative humidity. It considers that the magnitude of increased rainfall for river basins varied is from 2-19% of mean per 100 years. The increase of heavy rain from 9-27 mm per 100 years over different river basins with reduction in the number of rainy days suggest the possibility of increasing intensity of floods. Moreover, it is believed that an increase in areal magnitude of vegetation cover as well as rainfall over the last period has increased the moisture in the atmosphere through enhanced evapotranspiration, which in turn has increased the relative humidity.
