Thanks to Kurumi and Natsume’s help Ranma has been able to perfect this technique. A typhoon is created by heat energy emitted when water vapors coming from the hot ocean surface forms clouds. The wind blows faster the more of a temperature difference there is. By utilizing the Dai Yon Ha Dou to block opponents attack the temperature differences changes the air pressure, which creates a gigantic whirlwind of scorching heat. Ranma can also use a weaker version of this technique agitating molecules in the air to create enough energy to deflect other energy attacks.
