Best answer: Why does a warm front bring a light and steady rain?

Why do warm fronts cause rain?

A warm mass of air will generally hold moisture picked up as it passes over large areas of water through the process of evaporation. As this warm moist air rises it cools and the water vapor condenses into rain. So a warm air mass tends to bring with it plenty of rain and drizzle.

What causes steady light rain?

A front is considered to be a warm front when the warm air overruns the cold air. This type of frontal system is associated with the gradual ascent of the air, leading to stratiform clouds and steady precipitation.

What type of front brings light rain and warm air?

Warm Fronts

They are associated with warm air moving over cold air and are more likely to produce large regions of light to moderate rain, drizzle or snow. Cirrus clouds and alto cumulus, along with fog, often precede warm fronts as they move through an area.

What type of rain is associated with a warm front?

Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow. After the warm front passes, fair and milder weather is typical, however, a cold front is likely not far behind.

Why is warm front not associated with heavy rain?

The air behind a warm front is generally warmer and more moist than the air ahead of it. … The air mass behind a warm front is likely to be warmer and more moist than the one before the front. If a warm front is approaching, light rain or light winter precipitation is possible before and as the front passes.

Which front brings drizzly rain and warmer clear weather?

Air Masses and Fronts

A B
warm front warm air moves over cold air; moves slowly and brings drizzly rain. Warm weather follows.
occluded front warm air mass caught between two cold air fronts; brings large amounts of rain and snow. Cooler temperatures follow.

What type of front brings light rain and drizzle well in advance of the front reaching the surface followed by clear warmer weather?

Cold Fronts and Warm Fronts

Warm fronts usually move from southwest to northeast. A warm front can initially bring some rain, followed by clear skies and warm temperatures. A cold front is the transition area where a mass of cold air moves in to replace a mass of warm air.
