Heat Transfer
What is heat transfer?
When heat moves from one object to another.
A violently rotating column of air extending from the base of a thunderstorm down to the ground.
A tornado
What is an air mass?
A body of air with specific characteristics
When an object or substance is in motion
Kinetic energy
What causes water vapor and air to rise into the atmosphere? [explain]
Thermal energy causes air and water vapor to rise because thermal energy increases kinetic energy of their particles which makes the substances less dense so they rise.
How does heat move?
Heat always moves from an object or substance that is hot to an object or substance that is cold.
An unusual weather phenomenon in which balls of ice,fall from the sky.
A hailstorm
What is a maritime tropical air mass?
A warm air mass that forms over water.
A boundary between where two air masses meet is known as a
Front
What happens to water vapor when it is cooled down?
When water vapor (a gas) gets cooled down, its particles begin to condense which tuns the water vapor into a liquid (water).
In order for heat to transfer, an object must have
thermal energy
A storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere.
A thunderstorm
What are the different types of air masses?
Maritime Tropical
Maritime Polar
Continental Tropical
Continental Polar
The distance between particles in an object or substance is known as its
Density
What makes up a cloud?
A cloud is made up of air, water vapor, ice crystals, and CCN (dust/tiny solids in the air).
Define Conduction, Convection, and Radiation
Conduction- Heat transfer by direct contact
Convection- Heat transfer through hot/cold currents or cycles.
Radiation-Heat transfer through open spaces by heat waves.
A storm with large amounts of snow or blowing snow, winds greater than 35 mph (56 kph), and visibility of less than ¼ mile (0.4 km) for at least three hours.
A blizzard
This air mass forms over the Gulf of Mexico
Maritime Tropical
What is precipitation?
Any liquid or solid form of water that falls to the ground from the sky.
What is the relationship between temperature and the amount of water vapor the air can hold?
What form(s) of heat transfer is happening in the scenario below:
Billy goes camping with his family. In the evening, the family builds a fire. The family feels warm due to the fire.
Conduction-Flame and wood (heat transfers to the wood by direct contact)
Convection-Air above the flame gains thermal energy and rises when it cools it sinks.
Radiation- The family feels the heat because heat waves travel from the flame to their skin.
It is named after the direction from which the strongest winds typically blow over the northeast states, including New England and the Mid-Atlantic states. The storms can bring wind, snow, rain and flooding to these regions.
A Nor'easter
This air mass forms over Iceland
Continental Polar
A measure of the average speed [kinetic energy] of the molecules in a solid, liquid, or gas.
Temperature
What do the weather conditions have to be in order for a large storm to occur?
Temperature of the ground needs to be warm, Temperature of the sky needs to be cold, and the humidity level needs to be high.
