A thunderstorm is a storm that produces thunder and rain, on average lasting about 30 minutes and averaging about 15 miles in diameter. There are four types of weather fronts that cause thunderstorms: cold front, warm front, stationary front and occluded front.

What type of weather can occur at an occluded front?

There is often precipitation along an occluded front from cumulonimbus or nimbostratus clouds. Wind changes direction as the front passes and the temperature either warms or cools. After the front passes, the sky is usually clearer, and the air is drier.

What type of front causes thunderstorms?

A cold front does the same thing with a warm air mass. The warm air is forced to rise because it is less dense than the cold air. This causes a surge of rising motion with is known to generate thunderstorms.
