The problem, of course, stems from the much dryer climate that you now live in. I am afraid there is not much you can do, but I will give you the options.
1. Saw top and leafs into strips and glue up in an alternating growth ring pattern, then replane to thickness. An unacceptable task in my estimation because it would screw up the quilted pattern and be easier to make new from scratch.
2. A scheme that works fairly well with a normal table top but not with leafs (because it shows) is to make parallel saw kerfs about 1/4" apart to within 1/8" of the top surface. The piece is now clamped down on a flat surface and strips of wood are glued in the kerfs. The strips cannot be too tight or you will set in a new warp. The whole thing is niggling and would show on the leafs. You might try this scheme; however, and then add bread board ends to the top and leafs to prevent future warpage. This would also hide the strips from all but the bottom so only the grandkids would notice. Also the strips could be a similar wood.
Good luck and report your success as I am most interested.
With best regards,
