I've been talking with a few hunter friends who have been slightly upset with having to get Silencing Shot in the Marksman talent tree.
A lot of them were unaware that you're able to "abuse" the Convalescence of Winds buff for both of the places that Skarr can spawn in.
I made a few screenshots and brief description on how to tame him at his spawnpoint closest to Kirix, using the Convalescence of Winds buff.
I posted this on wowhead as well, but seeing as it's the very last comment on Skarr, I'm not sure how many would actually see it.
Taming of Skarr:
Step one: Go to this platform and jump up to the island in front of you in order to receive the buff.

Step two: You're going to jump back to the platform that you were standing on just a few moments ago. You will have to stand still where I am standing in the screenshot, and then jump without moving forward.

Step three: Once standing on the platform you should stand exactly where I am in the screenshot, and face the same direction. You have to make sure that you have the Convalescence of Winds buff and don't have the Thermal Wind buff. If everything checks out, then stand still and jump.

Step four: When you're standing on the platform that you just landed on, then go stand where I'm standing in the screenshot. The buff will disappear if you go one platform lower. You will have a clear line of sight to Skarr when standing here. You may want to keep in mind that the cast bar might be off. I have tried this 4 times now, and each time the tame was successful even tho the casting stopped halfway.

Step five: Bask in your new pets glory.
