Rains expected in extreme South Peninsula

30th November: "Ditwah" though not organised and bands not very prominent, still showing strength and heavy downpours in T.N.

Extremely cool days in T.N.  

2nd coolest November for Delhi since 2011

Delhi safdarjung avg. minimum temperature this November is 11.38c, this is the 2nd lowest avg. minimum temperature in Delhi in November since 2011. 

The graph shows the average. minimum temperature in Delhi from 2011-2025. Vertical lines show standard deviation (variability in temp). Data: IMD

"Ditwah " effect 

In Sri Lanka 

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

Air Quality Index...29th Evening 

Cyclone Senyar Breaks All Rules — A Bay of Bengal Cyclone Reappears in the Pacific!

A very rare event: The remnants of Cyclone Senyar, which formed earlier in the extreme Southeast Bay of Bengal, have re-emerged in the western Pacific as a tropical depression. In a normal scenario, cyclones from the Bay of Bengal do not travel into the western Pacific Ocean.

 NEW PAGE INTRODUCED IN OUR BLOG..."GENERAL NON WEATHER MATTER"

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

Cyclone "Ditwah  causes massive damage to Sri Lanka with torrential rains:

3 hrs ended 5.30 Today 28th

27th Night :

Cyclone "Ditwah" forms over Sri Lanka. 

CURRENT STEERING MECHANISM: 

*LOW-LEVEL SUBTROPICAL RIDGE (STR)

TO THE EAST AND SOUTHEAST.... SYSTEM WILL Skirt T. N. COAST

*Land friction effect

*South-West wind flow will weaken it fast

*Poor TPW support.. Weakening the System. 

Outlook for the weekend 28thNov. - 1st Dec. 

For T. N & A. P. Coast

For Mumbai and Pune.

Mumbai: FAQ..(i) Has the Mumbai winter gone (ii) will the pollution reduce soon.

We have explained the cause of the pollution in our previous post... Weather related. 

Mumbai can expect a change in winds from Saturday... Hence pollution can reduce from Sunday.

Temperatures are expected to become slightly better from Sunday when 

Mumbai can expect a nominal fall in night Temperatures by 2/3°...to become around 19/20°.

Pune : After a rise in night Temperatures seen recently, a fall to 12/13° from Sunday 30th November ...definitely better and cooler

26th November 

Much discussion is taking place on the Pollution topic...and Delhi 👇seems to be the most " on line".

But, Mumbai 👇 is also now seeing polluted air since a few days.

 

Mumbaikars Blame smoke, construction, gases or even a far away volcano erupting.

But, the real reason is the weather condition..."Temperature Inversion ".

*What is a Temperature Inversion?

A temperature inversion occurs when air temperature increases with height, instead of decreasing. This creates a stable “cap” of warm air above cooler air near the surface.

*Why it causes discomfort? 

1. Stability and Lack of Mixing

Cool air below is dense and heavy. Warm air above is lighter.

This stops vertical mixing, locking the cool air in place.

2. Pollution Trapping

Smoke, dust, vehicle emissions, industrial pollutants, and even natural aerosols remain near the ground.

This can lead to haze, smog, respiratory discomfort, and low visibility, especially in urban basins

*Common Situations Where Inversions can Form

-Clear, calm nights: Ground cools rapidly → air near surface cools faster.

-Valleys and basins: Cold air sinks and gets trapped.

-Coastal regions: Sea breezes and cold ocean currents help form marine inversions.

-Winter: Longer nights and weaker sunlight make inversions more frequent and longer-lasting.

26th Noon (Revised):

(A) Cyclonic Storm "Senyar" [Pronunciation: 'Sen-yar'] over Strait of Malacca and adjoining Northeast Indonesia and

Very likely to maintain the intensity of cyclonic storm for next 24 hours and then weaken gradually.

IMD revises Path from previous Track..

(B)  (B) Well Marked Low pressure area over southwest Bay of Bengal and adjoining areas of Southeast Sri Lanka & Equatorial Indian Ocean...Likely to move NNE and become a depression....IMD

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

25th Night...11 pm

Many international agencies classify and track “Tropical Cyclone 04B” using 1‑minute average sustained winds, while IMD uses 3‑minute averages and its own classification/tracking conventions, so numbers and even timings can look different but refer to the same system.

Both methods are valid; they just follow different World Meteorological Organization–accepted practices.

Wind averaging differencesIMD defines maximum sustained wind as the highest 3‑minute mean wind at 10 m height within the cIyclone circulation.

Agencies like the U.S. National Hurricane Center and Joint Typhoon Warning Center use a 1‑minute mean wind at 10 m.Because a 1‑minute average captures shorter gusts, 1‑minute “sustained wind” values .

Tracking differencesAgencies use slightly different analysis techniques (satellite methods, model blends, weighting of observations), which can give small differences in estimated position, track, and intensity at a given time.
