How come there are no storm tracks west and east of South America?
I would have thought the same mechanism would be at work there as in north Pacific, Atlantic and the South Indian Ocean.

I think the southern oceans and atmosphere tend to be a bit cooler due to the lack of land masses south of the equator. That probably has something to do with it.

Interesting question...but maybe Climate Change isn’t so active due to peioples activities down there....?/s

Basically, because there is little land area to concentrate the warmth of the Sunlight to drive the formation of the only valid “Green House Gas” = Water Vapor H2O. Willis Eschenbach at WUWT has a good explanation of the actions involved:

Notice that there are no hurricane tracks through the center equatorial region (about +- 8 degrees latitude north and south). Funny that. Where it is hottest, there are no hurricanes. The lack of equatorial hurricanes means that a significant part of the South American land mass, is located where no hurricanes form.
