water pushed over the land, or inland flooding caused by huge amounts of rainfall often generated by lesser
tropical storms hung up over coastlines.

waters of the
tropical Pacific that
occurs every three to five years, temporarily affecting weather world - wide).

De Witt, are you saying «THS???» because you don't know it stands for
tropical hot spot [which I can't believe] or because you don't get the connection between backradiation and a THS, which I understood to be the case because the Troposphere would warm faster than the surface since it is being heated by a warmer surface, to wit, the surface of the planet which is getting warmed by the aforesaid backradiation; and in addition to but not withstanding that the troposphere whould also rise which would be another aspect of the THS, with the final characteristic being that said THS would
occur in the tropics where the warming effect of extra
water would be most pronounced, also as a consequence of backradiation?
