What Type of Weather Signals a Warm Front?

Question

Prior to and after the passage of one.

Answer 1

I couldn't resist answering this question.

Let us look at this as an ideal warm front setup in the eastern US in the winter time. Let's say you live in DC, heaven forbid.
You are north of a northward moving warm front. The air is cold with an southeasterly wind blowing. Cold air is denser than warm air, and the cold air around you is acting as a barrier to the warm air to the south of you. However, southerly winds aloft are advecting warm air above you and over the cold dome of air you are feeling. As this warm air is lifted by the dome of cold air, water vapor condenses to form clouds. As the warm front nears your location, the cloud base lowers. Sincer warm air is streaming northward above cold air, an inversion (temperature is warmer than air underneath it) is in place. This level of the inversion lowers as the warm front gets closer to you. Moisture builds up in the layer beneath the inversion since it can't excape upward (upward motions capped by the inversion). Drizzle begins to fall; fog developes with the chilly wind. Rain may occur. All-in-all, the weather is gloomy, damp, and cold.

When the warm front passes, the winds shift from a southerly direction. The fog lifts and the drizzle ends. the cloud bank recedes in the direction the warm front is moving. The sun may come out or the stars. The air is noticably warmer. You will have no doubt a warm front has past.

Answer 2

That would depend if the warm front is occluded or not.
If the cooler layers get below the warm, there may either be a bit of mixing and possible rain and storms, or a spell of cooler weather. If the cool air mass meets the warm air mass, you will have a strong storm or even tornado coming.
If the warm air mass gets pushed down, then it will be hot weather and even a thermal inversion may happen if it is trapped. Smog will be bad, and temperatures will keep be stifling.

Answer 3

usually there is a warm front after another in the same day
its usually and warm followed by nice weather then a cold front and then cool temps after it.

Answer 4

So basically like malinmo

you're going to get stratiform type clouds. Fog, rain, drizzle. (stable air)

with the cold front, you're going to get Cumuliform type clouds, rain showers, Thunderstorms, etc..
(unstable air)

how about looking in the text book???

Answer 5

Prior: lowering cloud bases

Answer 6

Listen idiot, if you don't know, why do you claim to be a meteorologist?? Why not admit you are out of work, on welfare and sit on Yahoo 24/7 just dreaming.

Idiots admire you cos you are stupider then them

Footie
