Santa Cruz , Mumbai,  Rainfall data Analysis.

Rainfall data available from 1950 to 2025 shows that of the 72 years data for rainfall for the month of May during this period, 11 counted as extremes defined by greater than or equal to thrice the normal rainfall for Santa Cruz, namely 11mm. There were 11 of them (Table 1). 

When the wave of worldwide dam content change for May hit Santa Cruz, Mumbai, it generated enormous heat input shock as measured by the Average shock Input Temperature, deg C, every minute, in May, per unit dam content change, BCM during the month varying from 4.28 in May 1962 to 23.82 in  May 1974. The Extreme Total Rain in May during the period forms a 6^th degree polynomial nonlinear correlation(R) with its R^2 measuring 0.83 with the Average shock input temperature during May of each extreme rain year. See Ch10Figure10 below.

For this simulation the earthquakes were used as proxy for the worldwide dam content changes. The source used was USGS earthquake search at the website of usgs.gov.in
