@Pavan, i too have given up on Pune, seems this once in a lifetime drought (i hope i never see it again), i bet we might not even get 20 cms entire season. better start saving some water, there is nothing left to save though
Thanks Rajesh. Yes, I'll remind you on wednesday. :)
At last delhi getting rains ,more than 60mms in the past few hours.
Hi Rajesh,
What does it mean that the northern trough is getting active? Does it mean that it will rain the north and not in the west? My question is : are these things a zero sum game? Just trying to understand how the monsoon works.
Thanks,
anonymous: I have explained in wednesday's blog, that the Northern trough gets active, and the off shore western trough gets weak. It happens as a sequence, bcoz the monsoon trough being north cannot host any systems from either seas. and, the SE winds from the Bay rush moisture into the Eastern parts of India, and into the region North of the trough along the Northern plains. So, the predicted rainfall on Friday..BTW, if you can identify yourself good, or mention where you are from..i do not enjoy chatting with anonymous people -:)
What is a "zero sum Game ?"
Hi Rajesh,
Thank you for your response on the northern trough. My name is Vivek and I am based in Gurgaon.
Your website is excellent. Thank you for the effort you put in to maintain it.
A zero sum game is a term from game theory/economics. In a zero sum game one person's gain is another person's loss. My question was if rain in the north was at the expense of rain in the west.
BTW most economic interactions are not zero sum. All trades benefit both parties in the trade. Why else would they enter the trade?
You can read up zero sum games

Thank tons again,

Vivek.
Hi Rajesh,
Its been almost 35 days and we are yet to see BB1, are conditions so adverse that this will be the first monsoon where we might not see low in low leave alone a deep depression. (i remember 2002 was a bad July year)
Regards, Ananth
Vikek - Most of weather predictions are based on statistical models based on simulations (taking in account currrent weather patterns - presume 16-20 factors and simulating same for future tenor points) or can be based on approximations - analytical models based on regression analysis.
As far as we know east and west may not have negative correlations - there are instancs when both are volatile or opposite. Anyway Rajesh sir can explain better.
vivek/sset: Relation between Northern Monsoon axis in the UP/Delhi region and West coast rainfall is always there...weakens the off shore trough.
ananth:Yes. Numbering the Bay system is almost forgotten..its been so long now -:))
Thank you Rajesh and sset.
