When a typhoon is still on the ocean, if a big bomb or several bombs are thrown to it, maybe at the eye, or at the part where the wind circles fastest, can the bomb destroy the typhoon?
No, it would just be a waste of money. The natural forces that fuel a typhoon, which absorbs energy from solar heated oceans, dwarf ordinary bombs into insignificance and are comparable but superior to the most powerful H-bombs ever tested (15 - 50 megatons). There is, of course, no question of dropping an exceptionally powerful H-bomb on a typhoon, that would only make things worse. As proof that typhoons derive their power from solar heated oceans, you need only observe their behaviour when they reach landfall. Their power rapidly dwindles away.
