What is a front in science?

A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity. 7 - 12+ Earth Science, Geography, Physical Geography.

What are 4 types of fronts?

There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

  • Warm Front. Weather map showing a warm front. ...
  • Stationary Front. ...
  • Occluded Front.

What do the fronts mean?

Fronts are boundaries between air masses of different temperatures. Fronts are actually zones of transition, but sometimes the transition zone, called a frontal zone, can be quite sharp. The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass.

What happens at a front?

At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone. If the lifted air is moist, there will be condensation and precipitation. Winds are common at a front.

What causes wind?

Wind is caused by uneven heating of the earth's surface by the sun. Because the earth's surface is made up of different types of land and water, it absorbs the sun's heat at different rates. One example of this uneven heating is the daily wind cycle.

What is front meteorology?

A weather front is a boundary between two air masses. It can be thought of like the frontline in a battle, where the warm air represents one side and its 'enemy,' the cold air, the other side. Across a front, there can be large variations in temperature, as warm air comes into contact with cooler air.

Why is a front called a front?

front, in meteorology, interface or transition zone between two air masses of different density and temperature; the sporadic flareups of weather along this zone, with occasional thunderstorms and electrical activity, was, to the Norwegian meteorologists who gave it its name during World War I, analogous to the ...

What is a moisture front?

Dry Line a moisture boundary. A dry line is a boundary that separates a moist air mass from a dry air mass. Also called a "Dew Point Front", sharp changes in dew point temperature can be observed across a dry line.

How are fronts formed?

Such a front is formed when a cold air mass replaces a warm air mass by advancing into it or that the warm air mass retreats and cold air mass advances (cold air mass is the clear winner). In such a situation, the transition zone between the two is a cold front. Cold front moves up to twice as quickly as warm fronts.

What are the characteristics of fronts?

What Is A Front? A front is defined by the transition zone or boundary between two air masses with different characteristics including: temperature, wind direction, density and dew point.

Which front will bring rain?

A warm front forms where warm air moves over cold, denser air that is leaving an area. The warm air replaces the cold air as the cold air moves away. Warm fronts generally bring drizzly rain. They also are followed by clear, warm weather.

What is air masses and fronts?

Resources. An air mass is a body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, or millions of square kilometers. A front is the boundary at which two air masses of different temperature and moisture content meet.

What is a pressure front?

Surface low pressure systems usually have fronts associated with them. A front represents a boundary between two air masses that contain different temperature, wind, and moisture properties. Here, a cold front is shown which can be present any time of the year, but is most pronounced and noticeable during the winter.

What air mass is cT?

Continental Tropical air masses (cT) are a type of tropical air produced by the subtropical ridge over large areas of land and typically originate from low-latitude deserts such as the Sahara Desert in northern Africa, which is the major source of these air masses.

What is wind Ducksters?

Wind is the movement of large amounts of air. Even though we can't see air, we know that it is made up of molecules of different kinds of gasses, mostly nitrogen and oxygen. When lots of these molecules move, usually in one direction, we call this wind.

What are the 3 types of winds?

Broadly, there are three types of winds – prevailing winds, seasonal winds and local winds.

What are kindergarten winds?

Wind is the movement of air near Earth's surface. Wind can be a gentle breeze or a strong gale. The most powerful wind happens during storms called tornadoes, cyclones, and hurricanes. Changes in the temperature of air, land, and water cause wind.
