What are air masses that form over oceans called?
Air masses that form over the ocean, called maritime air masses, are more humid than those that form over land, called continental air masses.
How do air masses get their characteristics?
Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate. Upon movement, air masses displace residual air over locations thus changing temperature and humidity characteristics.
What happens when two different air masses meet quizlet?
What happens when two air masses meet? When two air masses meet, they form a front, which is a boundary that separates two air masses of different properties. How is a warm front produced? A warm front forms when warm air moves into an area formerly covered by cooler air.
What happens when two air masses meet quizlet?
What happens when air masses meet? When two large air masses meet, the boundary that separates them is called a front. Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink.
What type of front occurs when a warmer air mass is pushing into a cooler air mass?
warm front
What happens when one air mass overtakes another air mass?
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. The greater the temperature difference between the two air masses, the stronger the winds will be.
What will happen when a fast moving cold air mass runs into an existing warm air mass?
A cold front forms when a cold air mass runs into a warm air mass (Figure below). The cold air mass moves faster than the warm air mass. As the warm air rises, its water vapor condenses. Clouds form, and precipitation falls.
What is it called when a warm air mass is caught between two cold air masses?
Occluded Fronts- a warm air mass is caught between two cooler air masses.
What is a large body of air that has similar temperatures?
A huge body of air that has similar temperature, humidiry and air pres- A sure throughout it is called an air mass. Scientists classify air masses according to temperature and humidity. Tiropical, or warm, air masses form in the tropics and have low air pressure.
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.
