Indicator 3: Annual ‘Min’ Temperature
The mean ‘Minimum Annual Temperature’ in Bangalore from 2001–2013, as
availed from the IMD, amounts to 15 °C with a standard deviation of 0.5 °C (as
shown in Fig. 6).
The data availed from the IMD data for Bangalore as shown in the above graphs
tells us that there is a variation in the temperature among different years but there
has been no such increase of temperature.
The maximum average temperature recorded in the study area from 2001 to
2010 amounts to 29 °C and the average minimum temperature to 18 °C with a
variation of 1 °C in the mean maximum temperature and 0.9 °C mean minimum
temperature (as shown in Fig. 7); this shows there is a very slight variation, but not
an increase in the temperatures over the last decade. Except a drought occurrence
53–60 years ago, there are no extreme events like hot waves recorded in the region
and as the above graph also shows temperatures being moderate over the said
decade, it can be surmised that there is no climate change in the region.
