Rainfall

Rainfall is the result of water vapor condensing and precipitating, forming droplets that fall from clouds due to gravity. It is an important part of the water cycle. Global warming is often taken to refer to global increases in temperature accompanying the increases in greenhouse gases in the atmosphere. When the temperature increases, so does the water-holding capacity of the atmosphere. The increase in surface heating can indeed increase surface temperatures but it also increases evaporation. The distribution of the world’s rainfall is shifting as our climate changes. Wet areas may become wetter, dry areas drier, storms more intense, leading to more chaotic weather around the world. According to the Intergovernmental Panel on Climate Change, an increase in the average global temperature is very likely to lead to changes in precipitation and atmospheric moisture, including shifts towards more extreme precipitation during storms. As the lower atmosphere (the troposphere) becomes warmer, evaporation rates increase, which leads to an increase in the amount of moisture circulating. When the troposphere has more moisture, more intense precipitation occurs, thus potentially triggering more flooding over land. Conversely in other areas, warmer temperatures may lead to increased drying accelerating the onset of drought. Rainfall analytics will enable the users to visualize and compare district-wise observed rainfall as well as projected values based on RCP scenarios. The analytics in the form of bar charts and trend lines facilitate the users to easily visualize the changes for enhanced user experience.
