What is cold front??

Question

and warm front?

(:

Answer 1

Well a front in general is the leading edge of an air mass. So if you have a cold front, you have cold weather behind that line. Warm front will have warm air behind the line. By line, I mean on a weather map when they have those lines on the map with triangles (for cold front) or half circles for warm fronts.  To determine if it is a warm front or cold front you would want to look at temperature around a certain area, look at the moisture and look at the wind speed and direction.

Answer 2

A cold front defined as the leading edge of a cooler and drier mass of air. The air with greater density wedges under the less dense warmer air, lifting it, which can cause the formation a narrow line of showers and thunderstorms when enough moisture is present. This upward motion causes lowered pressure along the cold front. On weather maps, the surface position of the cold front is marked with the symbol of a blue line of triangles/spikes (pips) pointing in the direction of travel. A cold front's location is at the leading edge of the temperature drop off, which in an isotherm analysis would show up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface trough. Cold fronts can move up to twice as fast and produce sharper changes in weather than warm fronts. Since cold air is denser than warm air it rapidly replaces the warm air preceding the boundary. Cold fronts are usually associated with an area of low pressure, and sometimes, a warm front.

Answer 3

Weather moves according to temperature changes. At the front of a cold air mass is a cold front; a warm front is in front of a warm air mass.

Warm air rises over a cold air mass so a cold front moves across over us generating dropping temperatures.

Answer 4

A front is a boundary.  Cold ones move faster and lift warmer

air, which can create storms.
