What front occurs when a fast moving warm air mass overtakes a slower moving cold air mass?
occluded front forms
What happens when two different air masses meet?
When two air masses meet together, the boundary between the two is called a weather 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.
What can happen if there is a large temperature difference between two nearby air masses?
If the temperature difference between the two air masses is high, then the winds will be strong. Fronts are the main cause of stormy weather.
What factors cause air masses to move in the US?
One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.
How can heat affect the movement of air masses?
The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses. A warm front marks the leading edge of this warm, moist air mass.
What kind of air mass would be warm and dry?
Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
What front forms when a warm air mass is caught between two cold air masses?
An occluded front forms when a warm air mass is caught between two cooler air masses. The warm air mass is cut ofl or occluded’ from the ground. The occluded warm front may cause clouds and precipitation. A swirling center of low air pressure is called a cyclone.
What are the two main characteristics of air masses?
What two characteristics are used to classify air masses? The two characteristics that are used to classify air masses, are temperature and humidity. Classify the four major types of air masses according to whether they are dry or humid.
What characteristics do all air masses have in common?
Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties.
What are the four major types of air masses according to moisture content?
Generally, there are four types of air masses that can be further categorized with specifics of where they occur and over water or land. The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.
Which two air masses have the greatest influence on weather east of the Rocky Mountains?
Which two air masses have the greatest influence on weather east of the Rocky Mountains? Explain your choice. The air masses which have the greatest influence on weather east of the Rocky Mountains are Continental Polar (cP), Continental Arctic (cA) and Maritime Tropical (mT) Air Masses.
