Do stationary fronts cause thunderstorms?
Sometimes a stationary fronts could produce severe weather. There could be a band of thunderstorms or heavy rain may be pushed down from the front, which could lead to flooding. On occasion a derecho is a fast-moving area of strong straight-line winds that are sometimes produced along stationary fronts.
How do fronts cause thunderstorms to develop?
In a supercell, a moist, unstable body of warm air may be forced to rise by an approaching cold front. … The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow.
What front causes rain?
However, as a cold front comes in and drives under the mass of warm air, the warmer and moist air will be forced upwards. As the warm air is pushed higher, the moisture it carries condenses and falls as rain.
What do stationary fronts cause?
At a stationary front the air masses do not move. A front may become stationary if an air mass is stopped by a barrier, such as a mountain range. A stationary front may bring days of rain, drizzle, and fog. Winds usually blow parallel to the front, but in opposite directions.
