Congratulations, You got the wikiwarning brought to you by exxxxon and friends 👏
Thanks but not sure exactly what this means.
Thanks you for the reply @@RaghuMurtugudde It means that those with money have power. Those with lots of money have lots of power. Which means we live in a Corporatocracy Empire. They own our Gvts. medias, etc. IMF says: "Fossil Fuel Subsidies Surged to Record $7 Trillion" in 2023. "Money begets power, power begets money." Exxxon knew in the 1970's. it is documented. Yes, the world does not work as we assume, at least, the human part of the world. We do understand the Physics and Evolution quite well.
Thakyou for such crystal clear explanation
Glad that they help. Feel free to share. Thanks.
How to download frequency and intensity sir?
Not clear what you are asking but if you are talking about cyclones then y ou will have to go to the databases that serve world cyclone info. The details may not be enough to get frequency and intensity of individual cyclones. Best.
Thank you Sir 🙏
Glad that these help. Feel free to share. Thank you.
Professor thank you to upload this best video, the problem of this video is very short. what is the energy interval of potential and kinetic energy per unit mass in the troposphere and lower stratosphere?
Videos are presented as podcasts. You need to spend more time learning and see how the method I presented can be used to derive the vertical distribution of PE and KE. All the data is available as reanalysis products. Best.
@@RaghuMurtugudde thank you.
thank you sir👏🏻
Glad that they help. Feel free to share. Thank you and best.
I have the value of zonal wind, how can I get meridional wind speed from zonal wind speed? thank you
You cannot.
Really I love all your upload videos. thank you
Thank you Sir for this precise explanation.

Sir thankyou for taking out your time noticing my massage , sir youy lecture is v. beneficial it helped alot in understanding basic oceanography
Glad that they help. Feel free to share. Thank you.
amazingly expalined sir
Glad that they help. Please feel free to share. Thanks.
Nice explanation. I have a question about trace gases exchange between troposphere to stratosphere (water vapor) and stratosphere to troposphere (ozone over shooting). How can we calculate the mass of water inserted into troposphere to staratosphere and mass of ozone down ward from stratosphere to troposphere in a given data?
If you have the data then just do the flux calculations of any quantity in any direction. Best.
@@RaghuMurtugudde Yeah, I have ozone and water vapor data from Aura MLS satellite. Thank you your response I will ask you if any difficulty.
can you kindly name the book for the chapter " TC - Chapter 13 - Near-Equatorial Precipitation Distribution" ?
Dynamics of the Tropical Atmosphere and Oceans by Peter Webster.
Thank you, great video for my exam prep!

can u give the review title plz i need it for an essay
The doi is always included in the podcast but you can also use google? Blue carbon as a natural climate solution Peter I. Macreadie, Micheli D. P. Costa, Trisha B. Atwood, Daniel A. Friess, Jeffrey J. Kelleway, Hilary Kennedy, Catherine E. Lovelock, Oscar Serrano & Carlos M. Duarte
@@RaghuMurtugudde I did not find the DOI and thank you very much for the help and fast reply.
Nice explanation sir
Glad that the podcasts help. Feel free to share. Thanks.
The presentation was excellent until the Mann Hockey Stick. How on earth does someone with this sort of knowledge have no knowledge of the delusion right in front of him. Not only has there been no warming in the last 60 odd years (radiosonde balloon and satellite data NOT surface corrupted rubbish) it looks like we are heading towards a serious cooling period. In Australia our summers are cooler and shorter and the never ending droughts predicted by our halfwits have resulted in flood after flood!!
Mother Nature doesn’t care if we agree with her or not. All the best.
Hi professor, can you explain to me how to calculate the variable eddy viscosity with depth
Look at the general formula and see what data you need and what resolution. Only possible with LES or DNS or microstructure data that is long enough within an eddy. I only worry about large scales and the low-frequency or spatial rectification of such details are hard to quantify. So I tend to ignore them.
thank's professor so much@@RaghuMurtugudde
Hello from the U.S.! Im a fan of your channel and love learning. Thanks so much!
Great to hear! I spent much of my life in the US but returned to India only in 2018. Please feel free to share. Thank you.
why is called fusion, since the boron, after capturing a proton, is transformed into smaller particules, alpha particules! It is in fact a aneutronique FISSION!!
Good point but since two molecules are involved instead of splitting one, we stick to the terminology of fusion.
Thank you very much for, the clear explanation.
Glad that they help. Please feel free to share. Thanks and best.
Excellent work Professor. Do you have a more expansive course available ?
I have many courses on the two channels. Not sure what you mean by more expansive but see the ones that are already there. Thanks.
I think people are making up random hypotheses for side effects (the useless species for the food chain are exactly the ones needing little iron like green blue algae) when it's pretty clear this is the actual carbon sequestration of the planet in a nutshell with iron as the driver. Humans are responsible for throttling that pump (and life of the ocean) by sequestering probably 90% of the natural iron flow into the ocean from rivers by diverting 50% of water to agriculture and otherwise reducing sediments via hydropower etc. So the least we could do is restore balance and the sequestration pump by fertilization (and actually fishing is probably much less co2 intensive than agriculture so there's another plus). That being said, I doubt natural sequestration is fast enough to make a dent in what we have done. Back of the envelope, the ocean had to deal with 0.25 gt co2 yearly or so from vulcanic activity, and if the pump had been much faster we would not have any co2 in the atmosphere. And that was with abundant ocean life. So that's a far cry from the 1500 gt or so we put up there cumulatively or 35 gt yearly.
Iron fertilization has to result in actual export of carbon and that hasn’t been as successful so far as one expects. It’s a bit like cloud seeding. There are more experiments planned and more results will come in but scalability is definitely an issue either way. Blue carbon and other approaches have to add to the portfolio of ocean carbon drawdown. Thanks.
Thanks 😊
Glad that these help. Please feel free to share. Thanks.
CZcams has removed restrictions on access to videos on the eemian. I found your video by searching for the word "Eemian" when before it was impossible to find.

Glad to hear. Not sure why youtube had restrictions on the Eemian. Thank you for letting me know.
Thank you professor. At a given real temperature data, how can we calculate the wavenumber and wavelength of the equatorial wave in the troposphere and lower stratosphere?
Just take the dispersion relations that are available in any standard book and do it.
your lectures are very high level and informative
Glad that they help. Feel free to share. Thank you.
Sir , I had a confusion that below CCD carbonate dissolve at faster rate ( pH decreases with depth in ocean water)but in this lecture you mentioned that below CCD carbonate dissolve stops and get deposited
Did I say that? That’s wrong of course. Seafloor has to be above the CCD for deposition to happen. Let me correct that. Thanks a lot for pointing it out. I don’t know how I screwed up such a simple thing.
Sir thanks a lot for your lectures, it help me so much in understanding basics of oceanography
Tuba, I have added a correction at the end. Please see. Thanks again.
Thank you so much, your videos in this oceanography section help me a lot to understand the ocean and atmospheric circulation
Glad that they help. Please feel free to share. Thank you and best.
Sir how you got that accent.. it’s beautiful.. do you stay out side of India?
Thank you. Not sure what you are comparing to but I lived abroad for many years before returning to India.
Thank you for creating these. Very valuable knowledge
Glad that they help. Please feel free to share. Thank you for taking the time to comment.
Can you tell which book you are referring to here?
I provide the DOI in the podcast. Please pause and copy. Thanks.
Is it necessary that the layer at 100 meter depth travels in direction opposite to wind direction?
Go forward to other podcasts on the vertical structure of the mixed layer, currents, etc. You will see that the Ekman transport is real and computable but you don’t need to obsess about this simple dynamic of the Ekman spiral. It is an ideal but useful concept. It cannot be found in the real world.
Is it necessary that top layer moves at 45 degree angle?
These are ideal situations where you have a simple balance between wind forcing and ocean response. In reality, you will need to be realistic about the friction and momentum penetration.
@@RaghuMurtugudde thanks a lot...is it also necessary that the layer at 100 m depth travels opposite to the wind direction, or is it also a simplification?
In an ideal situation Only.
😊thank you
Glad that these help. Please feel free to share. Best.
Thank you for your explanation, it was very helpful. Could you please provide a detailed explanation of how to calculate the strength of Bjerknes feedback? I haven't found clear learning resources on this topic.
This paper is the best one you can find for getting to what you want - agupubs.onlinelibrary.wiley.com/doi/10.1029/2006GL027221. Best.
@@RaghuMurtuguddethank you for the video and also for providing this paper.
Hi. I am worldbuilding, and I am trying to get the climate zones of the planet I am making (sort of) correct. I have had a hell of a time figuring out the sesonal differences in the precipitation around the equator. This animation helped a lot. Thank you :)
Glad that the podcasts help. Feel free to share and all the best with your worldbuilding.
So where we see these black blobs means strong absorption as a greenhouse gas, deterring it from exiting to space?
Yes but it also depends on the wavelength. In the UV band, it is the incoming solar that is absorbed by Oxygen and Ozone in the stratosphere, for ex.
thanks sir, very helpful
Glad that they help. Please feel free to share.
Looks like there is little to no energy leaving leaving the atmosphere where CO2 absorbs. That means nearly 100% of potential energy that can be absorbed by CO2 is already absorbed therefore adding more CO2 won’t have much effect, since there is none leaving. commons.wikimedia.org/wiki/File:Atmospheric_Transmission.png
Very basic with little analysis.
This is an introductory course for beginners and not a research project. Thank you.
Thank you. This book I can find!
Google can help you find anything. Good luck.
Hello Sir, It would help if you add the all titles of the books and author names to video description as I couldn't find the second book via google search you mention in the video (I am probably not searching for it correctly). Thank you.
Tell me the name of the book I mention and I will show you how to search. Just to make sure you understood the name correctly.
Hello Sir, May I know if there's a text book to go with these lectures? Are the diagrams/tables from a particular text book? Thanks.
The book is mentioned at the very beginning in chapter 1, podcast 1. A free book from Roger Schmittner called Introduction to Climate Science. But figures are from many sources and usually a reference is listed in the slide.
