Vagaries of the Weather...is not an unusual phenomena...

It is seen that the cyclic variations occur over the years . This can be attributed to the various weather parameters  happening from meteorological events in certain periods of time.

Cyclic rotations are repetitive over the years. 

In Europe, currently, there is a freezing extended winter and most unusual cold snowfall in California. 

India saw the hottest February ever.






An early ( temporary) beginning to March 2023 with high temperatures and lack of winter ( WDs) systems. 


Mumbai saw hot weather for an unprecedented 8 days at a stretch with daytime temperatures 6c above the normal.

Expecting Mumbai to see some light thundershowers from 15th, and better day temperatures around 34/35°c.

We write ( temporary) as the heat waves in the Sub Continent is about to wane.

We do not expect any place in India to touch even 40c ,at least for the next 10 days into March.

All theories will vanish, as Nature first heated the Land, and consequently formes a Low pressure trough in Central India by Mid March. 

Early Pre Monsoon Showers expected..  Thundershowers with rain and hail is expected all over 

1. Central India ( EastRajasthan , M.P, Chhattisgarh,  parts of Haryana &U.P, Jharkhand. 

2. Peninsula India ( Maharashtra  Gujarat, Karnataka, Telangana).

3. Parts of Southern States. 

‐----------------------------------------------------------

Outlook: for 14th -20th March 

A wet spell of pre-monsoon rains is likely across the country - beginning tomorrow 14th March, and likely extending to 20th March!

Reasons:

- Strong Western Disturbance due to dip in Westerly Jet Stream at 200 hPa

- Trough of low and wind convergence in lower levels across peninsular India

- Lots of moisture pulled in from Arabian Sea and Bay of Bengal 

Thunderstorms with chance of hail likley across Maharashtra, Madhya Pradesh and western parts of Karnataka and Kerala starting from 14th March. 

15th-17th March to see the most widespread thunderstorms across the interior peninsula including Telangana, Andhra Pradesh and Tamil Nadu. 

Parts of Gujarat, Rajasthan, Uttar Pradesh, Chhattisgarh, Odisha, Jharkhand, Bihar and West Bengal to see thundershowers during the next 7 days. 

Outlook prepared by Vagarian Shreyas. 


Sunday, March 12, 2023

Posted 12th March Afternoon:

Mumbai:

Its been hot and very hot last 10 days for Mumbai. With above normal temperatures to the extent of upto 6c above the average. The last 6 days..showing the trend.👇

Well, all this was attributed to the dominating Easterly winds, which constantly kept the Westerly sea winds at bay. Even the North winds , which could have provided relief, but were missing due to absence of Western Disturbances in the North. 

Now, with a Trough of Low pressure developing in the Interior Maharashtra region, the hot easterlies will cease to blow over Mumbai, and ....

From Tuesday 14th, Mumbai will see the days getting better at 34/35c..Much better then the high 30s. But, the sweat factor may increase, as the sea winds can increase the humidity levels..Light drizzle possible in some areas of city on 16th.

So, after 14th, for the week upto 17th, Mumbai will see around 34/35c in the day and partly cloudy skies. 

Interior Maharshtra  regions like Madhya Maharashtra, Marathwda  and Vidharbh can get showers and hail.

Heavy rains and hail possible in Sambhajinagar ( Aurangabad) and Marathwada on 15th/16th. Warning to farmers to take due precautions to cover the crops after thrashing.

15/16 रोजी संभाजीनगर (औरंगाबाद) आणि मराठवाड्यात पाऊस आणि गारपीट होण्याची शक्यता आहे. पीक कापणीनंतर झाकण्यासाठी योग्य ती खबरदारी घेण्याचा इशारा शेतकऱ्यांना

Pune can expect light showers on 15th/16th.

These showers in the interior are actually "advance  pre monsoon showers". The trough in the Interior Maharshtra and South M.P. region cause the moisture from the Bay and Arabian Sea to converge in the Central Peninsula.

Threatening MJO

Dr.Vineet's analysis ...More on his page

First time ever in history MJO line has gone out of the boudarylimits  of this plot


In terms of amplitude wise, it is third highest, just trailing behind 2015.

Important thing to note 2015 when such an amplitude of mjo was observed , very strong elnino followed

9th March:

El Nino and The South West Monsoon...Instead of going into panic mode, let us first understand the  current phase and possibility of an "El Nino" situation.  

El-Nino:

El Niño refers to a warming of the central and eastern tropical Pacific Ocean that can have compounded effects on global weather patterns. El Niño events can have significant impacts on the SouthWest monsoon.


But, there is no one-to-one direct effect between El Niño and the Indian summer monsoon. The quantum of impact may vary depending on the strength and timing of the El Nino event.

Overall in history.👇
Data from 1951 shows there were 15 moderate and strong El Nino events between 1951 and 2022.

As per information form records, In this period, the Indian monsoon was deficient (-10%) in 8 years and in another 3 years the monsoon rainfall was on the lower side of the norm ( -5% to -10%).

-------------------------------------------------------------

Technical Explanatory Note of Latest Scenario:

* La Niña has ended and ENSO-neutral conditions are expected to continue through the Northern Hemisphere spring (March/April)and early summer 2023.(May/June)(as per CPC)

*Equatorial sea surface temperatures (SSTs) are below average across most of the Pacific Ocean. 

*Niño 3.4 -0.2ºC

*The tropical Pacific atmosphere is consistent with La Niña. ENSO-neutral conditions are expected to begin within the next couple of months, and persist through the Northern Hemisphere spring and early summer.

**The ONI is based on SST departures from average in the Niño 3.4 region, and is a principal measure for monitoring, assessing, and predicting ENSO. Defined as the three-month running-mean SST departures in the Niño 3.4 region.

 El Niño: characterized by a positive ONI greater than or equal to +0.5ºC. La Niña: characterized by a negative ONI less than or equal to -0.5ºC. By historical standards, to be classified as a full-fledged El Niño or La Niña episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons. 

(CPC considers El Niño or La Niña conditions to occur when the monthly Niño3.4 OISST departures meet or exceed +/- 0.5ºC along with consistent atmospheric features. These anomalies must also be forecasted to persist for 3 consecutive months.)


The most recent ONI value (December 2022 – February 2023) is -0.7ºC.

Excerpts from National Oceanic and Atmospheric Administration (NOAA)

-------------------------------------------------------------

Expected Position Explanation:(As per Vagaries)


A perfect forecast of El Nino and how it will impact the South West monsoon will be seen only by May-June. Besides El Nino, there are other factors too influencing monsoons. 

So, the earliest that an initial El Nino can be called as "setting" is in June/July 2023. 

But we should  now expect an full fledged El Nino event by August-September.

Let's be Alert rather than confused.

We expect Mumbai to heat up to 38c again by Saturday/Sunday...but no rain of course. A dazzling hot 🔥 sun with dusty atmosphere..AQI could be around 300.

The blowing easterlies will keep the air dusty aided by the local conditions.

Warm stuffy at nights, as we do not expect nights to fall below 24c.

Interior Konkan could heat up to 40c.

Pune and Sambhajinagar (Aurangabad) will remain dry and around 36c in the day.
