Thank you and bless you for this good video sir! I finally understand the concept for this topic that i hardly to understand just by reading my lecturer notes 😭😭❤️❤️
Hi. I want to thank you so much because I've got this topic quite difficult to understand but your video + comment bellow have clearly explained me about this. thank you
The water in the car analogy doesn't make any sense to me. The water appears to move when the car is accelerating. But once the acceleration stops the water is still again. So unless the Earth's rotational speed is changing and the earth is accelerating this analogy does not work at all. I'm a student trying to work this out but your video hasn't helped. Sorry
Thanks for your comment. Like any analogy, there are limits to it. The bucket of seawater accelerating in a car analogy is a good first approximation to explain why the center of the subtropical gyre is shifted from the center of the ocean basin towards the western side. So the western side of the surface current gyre has all this water that needs to be moved through that area, hence western intensification. But I agree, in a steady state it doesn't fully explain western intensification. However, my experience is that students tend to grasp that better then other explanations. In reality, western intensification is caused by the difference in strength of the Coriolis effect with latitude (which itself is caused by the spinning Earth, hence the bucket of seawater analogy). For a more detailed explanation of what causes western intensification, see Figure 7.8 on page 217 in Essentials of Oceanography, 12th Edition. But that explanation, which includes geostrophic flow considerations, is a little more difficult to grasp.
Hey Al. I ending up finding the answers through extensive googling, but thanks for your comment. I think the Coriolis affect is easy enough to understand if its explained clearly, as is the reason for the difference in its strength between the poles and equator and hence western intensification. For some reason, however, I found the explanations for all of these things extremely hard to find on the internet and was thrown off by a lot of confusing analogies like 'the sloshing effect'. My opinion would be that it's better to just say it how it is.
Hi I just wanted to thank you I just didn't understand this topic even with re-reading the book over and over but this video and this comment made me go bk to the book, and I was finally able to put it all together thank you very much, and Jacob is also right there is not a lot of info out there to help explain this, and the car analogy also confused me, but now I can see why you use it. I am going to watch more of your youtube videos for my class and recommend it to others who were also struggling with this :)
Sir it was simply excellent. The way you explained western intensification was superb!!!
Thanks, Al! I still point my students to your videos. :) ~Gwyn Jones (Bellevue College)
Thanks so much for the great video, interesting and very helpful!
Very helpful. Taking a course with Lynne Talley at Scripps and this was very awesome review video.

No worries. Thanks, Jacob.
