Where I can get lecture notes/videos about EP flux and residual circulation?

I would like to learn more about EP flux and residual circulation. Recent studies using mainly GCM output and explain their results using EP flux and GW drag. As I learn from few study material, the EP flux is related to Eddies. Shall We use EP flux for explaining Tropical latitudes. I am also facing problem with plotting the EP flux vectors and residual circulation. So, I would like to learn in depth about these topics and also to get some hands on experience.

Thank you in advance,

With best regards

Dear Sir,

I suggest you can refer the following paper by Plumb (1985). You have lot more references to estimate plumb flux or EP flux in several paper later.

Good luck

Best regards

I am sorry I cannot help you. I am not a meteorologist, I am basically ionopsheric physicist.

Hi Kishore,

For lecture notes I suggest starting on this site:

http://www.staff.science.uu.nl/~delde102/AtmosphericDynamics.htm

Chapter 11, which discusses wave drag and Eliassen-Palm flux, is probably what your looking for and at the end of the document there is a list of ten or so references, which are probably of interest. The link to the Chapter 11 pdf is below:

http://www.staff.science.uu.nl/~delde102/AtmosphericDynamics2015bCh11.pdf

The site appears to be owned by Aarnout van Delden from Utrecht University, Netherlands.

In terms of plotting EP flux vectors I'd suggest start by looking here:

https://www.ncl.ucar.edu/Applications/EPflux.shtml

which points to the links below for further advice on calculating and plotting EP flux divergence.

There is also a reference to:

Edmon, H.J., B.J. Hoskins, and M.E. McIntyre,1980:

Eliassen-Palm cross sections for the troposphere.

J. Atmos. Sci., 37:2600-2616

Hope that's of some help,

Andrew
