Analysis of rain data collected by the Automatic Weather Station collected by Yuktix Technologies at the GKVK campus at Yelahanka shows that Sundays have been the rainiest days in the past 6 months.
The data shows that it has been continuously raining more on Sundays is the past 6 months in Yelahanka and the net rainfall that happened on Sundays is more than twice of any other day. While on one hand this could be a fun data point which could help event planners in picking the most appropriate day for event planning (it happens to be Friday), this begs a more serious question more serious question.:
Do the cars, factories and industry which are more active during the week affect our Weather pattern?
A similar pattern was discussed by Nature Magazine, which suggests that rain is most likely to occur along the US Atlantic coast on the weekend and the weather is most likely to be better on a Monday, Tuesday or Wednesday. According to them, this happened mostly on the account of a “natural” cloud-seeding effect created by the massive drift of pollution which followed a well defined weekly cycle.
This is not the only study that signals at human-made weather patterns. NASA also found correlation between day of the week and rainfall caused by pollution.
The data from Yuktix Weather Station can be accessed from here. You can clearly see that rains graphs are peaking around Sundays. It is for sure that the nature does not know which day of the week it is, whether it is a Tuesday or a Saturday.
“It has to be due to something that human beings are doing,” says Tom Bell of NASA’s Goddard Space Flight Center, “And one thing we do know that humans are doing is that they’re polluting the atmosphere more, at least in urban areas, for certain in the middle of the week” than on weekends.
