In the case of thunderstorms in front. it is the passage of violent gusts. floods: thunderstorms could a cold front which violent gusts, floods: thunderstorms could new will force the uprising of hot air. Since the cold air is heavy. spreads to the ground. its meeting with the hot air, which is volatile, will give it the push necessary to start the uprising.
