South West Monsoon Advances into Mumbai...Sunday 19th June

Vagaries Views on Advance of Monsoon and next 2 days Advance Estimate:

We are happy to note as mentioned in Last Article, good rains occurred in Marathwada. South Marathwada got good rains, prominent amongst them was
Bhokar 102 mms (Nanded Dist), Himayat Nagar 97 mms, Nanded with 60 mms, Umari and Hadgaon 55 mms, Ashti ( Beed) 38 mms, Kallamuri 19 mms. In Latur District, Nilanga got 37 mms, Latur got 34 mms, Chakur 12 mms. and Parbhani 12 mms. Umerga (Osmanabad)  got 51 mms and Lohara 46 mms.

The UAC moved towards Vidharbh/Telengana and then towards M.P. before dissipating. This dragged the South West Monsoon into Vidharbha. The west coast trough showed some strength on Saturday and Sunday, bringing in good rains to Madhya Maharashtra (South) and North Konkan. 
Monsoon also advanced upto Dahanu.

The moving system also brought some rains in Eastern areas of Gujarat.

Monsoon into Mumbai: Mumbai received some sharp showers on Sunday evening. By 8.30 pm IST, Colaba had measured 22 mms and Scruz 26 mms. Vagaries recorded 35 mms.
So, by Monday morning Mumbai may get the estimated 35-40 mms forecasted. 
Monday and Tuesday will be cloudy, with some showers. Rainfall amount will be around 25-30 mms /day.

[Our terminology for city forecast was given before, but i repeat: From least rain and increasing rainfall:
 i) A few showers ii) some showers iii) occasional showers iv) Fairly frequent rain showers v) frequent rain vi) intermittent rain showers vii) continuous rains.]

Good rains expected in North Marathwada (Aurangabad) and Nasik regions next 2 days.
Showers in West M.P. and reducing rains in Eastern region of M.P.
Increased rainfall in Kathmandu and Western Nepal from Monday for 3 days.

Latest ENSO Wrap-Up issued 21 June 2016

The latest ENSO Wrap-Up and Climate Model Summary are now available on the Bureau's website.

Chance of a negative Indian Ocean Dipole event increases
The tropical Pacific Ocean remains in a neutral El Niño–Southern Oscillation (ENSO) state—neither El Niño nor La Niña—with all ocean and atmospheric indicators now near normal.

Recent observations and climate model forecasts continue to suggest La Niña may develop in the coming months, hence the Bureau’s ENSO Outlook remains at La Niña WATCH. This means there is a 50% likelihood of La Niña developing during the second half of 2016. If La Niña does develop, climate models suggest it is unlikely to reach levels seen in the most recent event of 2010–12, which was one of the strongest La Niña events on record.

La Niña is typically associated with higher than usual winter and spring rainfall over northern, central and eastern Australia, and cooler than normal daytime temperatures south of the tropics.

Warm ocean temperatures to the north of Australia, in the Indian Ocean, and in the Tasman Sea, are also currently influencing Australia’s climate. Warm ocean temperatures surrounding Australia provide more moisture to weather systems that pass over the oceans and potentially change the path weather systems take, resulting in more systems reaching the continent.

Warm ocean temperatures to the northwest of Australia can be associated with a negative Indian Ocean Dipole (IOD), especially when they occur at the same time as cooler than usual ocean in the tropical western Indian Ocean, near the African coast. Climate models and current observations suggest a negative IOD may be in the early stages of development. However several more weeks of similar ocean temperature patterns would need to be observed before 2016 is considered a negative IOD year. Negative IOD events typically bring higher than usual winter and spring rainfall to southern Australia.

Both JAMSTEC and Australian Agency have forecasted negative IOD , which in turns means a drier monsoon for the western coast .

Rajesh Sir, Based on your experience , how much important is IOD for monsoon for Konkan and western maharastra, are the signs bad from an overall monsoon picture ?
