Thank you very much for the answer and materials. I am very beginner. Now I am going through these materials and may come back if I need more help.

I am a beginner of learning Tropical Cyclone. I would like to represent the extratropical transition of a tropical cyclone. But I can't understand on what actually in need to focus.

For a tropical cyclone, I can calculate time series of rainfall, maximum wind speed, minimum sea level pressure and discuss its features. Similarly, what are the quantities I should calculate to represent the extratropical transitions of the same tropical cyclone? and What actually I need to show?

Is it just simple discuss how a tropical cyclone changes its behavior when it moves toward the higher latitudes?

No, it is not sufficient to just discuss the behavior as it moves into higher latitudes. ET occurs because of environmental reasons, not geographical reasons.

How much of a beginner are you? My answer below may be a bit over your head if you do not know much about tropical cyclones. If that is the case, I suggest looking back at the theory and [basics](https://www.meted.ucar.edu/training_module.php?id=868#.XnubT4hKhPY) of tropical cyclones (structure, maximum potential intensity, etc.) to get a good grasp of what separates tropical cyclones from extratropical cyclones.

If you are specifically looking at quantities, I suggest looking at [cyclone phase space diagrams](https://journals.ametsoc.org/doi/full/10.1175/1520-0493%282003%29131%3C0585%3AACPSDF%3E2.0.CO%3B2). The variables in these diagrams include the thermal wind for different levels, as well as baroclinicity. [FSU has examples of cyclone phase space diagrams for different storms.](http://moe.met.fsu.edu/cyclonephase/)

Edit: I remembered two recent articles that review ET. They are [Evans et al. (2017)](https://journals.ametsoc.org/doi/full/10.1175/MWR-D-17-0027.1) and [Keller et al. (2019)](https://journals.ametsoc.org/doi/full/10.1175/MWR-D-17-0329.1).
