Hi Ravi, LTA is the long term average. I think it can be calculated over a period of 30 or 40 or 50 or 100 years (not sure).
IMD calls it the LPA (Long Period Average) and is calculated over a period of 50 years between 1951-2000 (I could see 1941-1990 used somewhere. I wish someone could clarify :-) ). IMD also classifies whether the monsoon is normal or not based on this LPA. +/-10% of LPA is Normal. (see http://www.imd.gov.in/doc/termglossary.pdf. Lots of definitions there) It would be interesting to have that 10% band on the rainfall tracker, and to highlight the drought years in Red or such colour. On similar terms, in the erratic months graph, it would be great to have the respective normal bands for the months so that we can see how erratic the rainfall actually is.
