- An empirical proof shows that there is an increase in the rainfall between 1871 and 2010 the increase is around 7% as per the analysis done by the Meteorological Centre (Met), Bangalore
- Met center’s shows an upward in the trend over 140 years and the 7% increase is in rainfall this period is expected in the backdrop of global warming as per the chairman of the Divecha Center for Climate Change in IISC
- He further opined that “Global warming does imply greater precipitation in areas where temperatures are rising, because this means a corresponding increase in atmospheric vapour,”
- As observed in the met center rainfall in Bangalore is consistent, analysis in rainfall data from a rain gauge in central Bangalore reveals that rainfall during September (city’s wettest month) increased by 40mm in 100 years
- But the department is yet to figure out whether the rainfall is getting more intense or the number of rainy days is increasing
- Bangalore is influenced of ‘heat island effect’, but the concrete surface begin to dominate a city’s landscape which create a temperature gradient between the more built-up center and the greener peripheries
- Local circulation is formed by increasing the amount of rainfall and due to urbanization across the state which is a major role in increasing rainfall here
- According to met center they too have observed “extreme weather conditions” in the state over a decade, seeing an increasing frequency of 24-hour rainfall in parts of the state
- Agumbe in Shimoga, called Cheerapunji of the south on August 1st, 2014 recorded 400 mm in a single day
