Saturday Night Update for Sindh:

not a drop since last 36 hours. I think around 4 lakh cusec of water is flowing in Mahanadi,in sambalpur.

sset said...

Thanks Rajesh sir, Rohit for good information.

We can see that entire south east Karnataka has received very low rain.. what ever we see is from start of monsoon and no improvement. I have noticed this same pattern for last 3 years and this region is very close / infact merges with Rayalseema and interior TN, therefor it is tending towards desertification. Infact these regions will not even receive rains in sept and very negligible NEM. Many cities and agricultural areas are in this zone.

Even if we randomly pickup least rain place from Marathwada for instance Augrangabad - 500mm is more than any of these places.

As given by Rohit in cms

mysore - 14,
chamrajnager - 08,
mandya -06 - Agricultural zone,
kolar - 11 - Agricultural zone,
tumkur - 18 - Agricultural zone,
chitrdurga - 19,
ramanagar - 16 - Agricultural zone,
Bangalore - 25 - saturated city,
mysore - 14 - saturated city

sset said...

North KAR many places like bagalkot,raichur,bagalkot,bellary also have received less rain but only saving grace is depression/lows over MAHA/Marathwada can bring some generous rain to them.

Has a new UAC formed in the BOB sometime back??

sset said...

Dear Villi - with respects for your weather knowledge-> myself as common person has observed change in SE interior KAR -> definite change on monsoon pattern/environment - these places are not even receiving 50% of normal rain.

Principal Component Regression - is one of the estimation techniques used for data mining -> weather predictions too use this model -> principal component analysis is used for data reduction.
