A cold front often brings intense weather changes such as thunderstorms while a warm front often brings light rain or drizzle. Why is
this the case?

In a warm front, the replacement of cold air by warm air is gradual while in a cold front, the cold air replaces warm air more quickly. It has to do with the pressure system. A cold front is a low pressure system and a warm front is a high pressure system. When talking about pressure, velocity of air particles is HIGHER when the pressure system is LOWER and is the reverse for HIGHER pressure systems. With this in mind, the higher moving particles during a low pressure system will cause a much bigger disturbance, aka thunderstorms

I hope this helps!

Explanation:

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
