Comparison cold front and warm?

Comparison cold front and warm?

  • Under the atmospheric front refers to the transition zone. Here there are masses of air, which have different characteristics. Atmospheric fronts occur when there is a collision of warm and cold air masses. Stretch air fronts for several tens of kilometers.

    The movement of air masses causes a change in the weather. At warm temperatures - warming. And if these air masses are cold, then expect a cold snap.

    Different air masses, depending on the source of occurrence. From arctic and polar to tropical and equatorial.

  • These fronts are completely different. Here are a few criteria by which they are different:

    1) Cold fronts move at a speed that is much higher than that of warm:

    2) It is known in advance when a warm front appears. And cold fronts, as a rule, arise unexpectedly.

  • The transition zone is the atmospheric front, which have different air masses. When a collision occurs, then warm and cold masses arise. I understood this well from the school curriculum. The air fronts themselves can stretch for several tens of kilometers. And their direction is directly related to the weather.

  • A similar table can be made taking into account that atmospheric fronts are places where air masses collide, which are different in their characteristic properties, where the main difference is whether cold air "presses" on warm air or vice versa.

  • If something is not clear - write in a personal. I will answer.

    1 - A warm front is formed, when warm air moves towards the cold one and displaces it (but warm air rises above the cold wedge because the warm air is lighter and less dense).

    Cold is formed when the cold air moves towards the warm, and a wedge swims under the warm air.

    2 - Warm front separates the front of the cyclone, the relatively warm part, and the warm sector.

    Cold front separates the warm sector of the cyclone and the rear (cold) part of the cyclone

    3 - Warm front characterized by the formation of clouds of ascending sliding: the family Cs - As - Ns (or Sc), that is, cirrostratus - altostratus - nimbostratus (or stratocumulus) clouds.

    Comparison cold front and warm?

    Cold front characterized by the formation of convective clouds, first As (high-cumulus), then Cu (cumulus), and at the end of Nb (cumulonimbus clouds)

    4 - With the passage of a warm front heavy precipitation is noted, in winter - heavy snow, in summer - heavy rain, which lasts several hours.

    With the passage of the cold front rainfall, thunderstorms, hailstorms, squalls, increased winds are noted.

    5 - Before passing the warm front the pressure drops dramatically. For example, it may fall on 3-3 and more hectopascals within 5 hours

    Before passing the cold front pressure drops unsharply, and can even grow.

    6 - Warm front usually moves slowly cold front faster, and at the end of the second stage of the cyclone’s existence, it overtakes the warm front and when they merge, the front of occlusion is formed.

    7 - Warm fronts generally moving from southeast to northwest, cold - from northwest to southeast.
