Great work Rohit. Monsoon in Mumbai city has entered defecient region. SWM 2017 for mumbai is missing Rajesh sir's script this time.

Thanks Rohitji for region-wise toppers. We see many new places in toppers list overtaking classic places. Hope this does not happen next year - for instance we see Mt.Abu same as Augumbe, Augumbe no longer in top slots - same goes with Kerala.
Hope Rajesh Sir is in good phase - probably doing deep research - leaving weather domains to new scientists like you and vagaries core group.

Long Range Forecast for the Rainfall during Second Half (August –
September) of the 2017 Southwest Monsoon and Updates for the
Seasonal Forecasts

Highlights:

 Quantitatively, the rainfall over the country as a whole during the second half of
the season is likely to be 100% of LPA with a model error of ±8%.

 The rainfall during August is likely to be 99 ± 9% of LPA as was forecasted in June.

 The seasonal (June to September) rainfall over the country as a whole is likely to be
normal (96% to 104% of LPA) as was forecasted in June.

1. Background and details of the 5- Parameter Operational Model

The forecast for the rainfall over the country as a whole for the second half of the 2017
monsoon season has been prepared using a Principal Component Regression (PCR) Model and
Monsoon Mission Coupled Forecasting System (MMCFS). The PCR model is based on 5 predictors
with a model error of ±8% of long period average (LPA). The LPA of the rainfall over the country as a whole for the second half of the monsoon season (August to September) based on the 1951-2000 period is 43.5cm (49% of the average season rainfall) with a coefficient of variation (C.V) of 15%.

2. SST conditions in the Pacific and the Indian Oceans

Since mid-March, warm ENSO neutral conditions are prevailing with SSTs over east-central
tropical Pacific close to El Niño threshold in recent weeks. However, the atmospheric conditions over the Pacific continue to reflect neutral ENSO conditions. Latest forecast from MMCFS indicates neutral ENSO conditions are most likely till 2018 spring season with high probability (80-90%) till end of 2017. Most of the other global models also suggest neutral ENSO conditions during the remaining part of 2017. Over Indian Ocean, neutral Indian Ocean Dipole (IOD) conditions are prevailing. The MMCFS forecast indicates nearly equal probabilities for neutral and negative IOD conditions to continue during the remaining part of the monsoon season.

3. Forecast for the Rainfall during the Second Half of the 2017 Southwest Monsoon
Rainfall and Updates for the Seasonal Forecasts

(a) The rainfall over the country as a whole during second half of southwest monsoon season
(August to September) is most likely to be normal (94%-106% of LPA).

(b) Quantitatively, the rainfall for the country as a whole during the second half of the season is likely
to be 100% of LPA with a model error of ±8%.

(c) The rainfall during August is likely to be 99 ± 9% of LPA.

(d) The seasonal (June to September) rainfall over the country as a whole is likely to be normal (96%- 104% of LPA) as predicted in June.

Tamilnadu was -21% deficit on 31 July to +10% above normal on 10th Aug.. So 31% gain in 10 days of break SWM !!

And SI Kar not benefiting from break SWM TS also as -33% deficit as till today.. Now whom @ sset would blame ? whether TN as SI Kar share is grabbed by TN as per his theory by saying Guj/Raj lows making SI Kar deficit ! So in break SWM TN gaining but SI Kar not so now who is stopping SI Kar.
