FRONTS
The boundary that forms between air masses.
What is a front?
The Earth's layer where most of our weather occurs.
What is the Troposphere?
The amount of water vapor in the air.
What is humidity?
A scientist that studies the weather.
What is a meteorologist?
This happens when updrafts and downdrafts (strong convection currents) suspend and then drop ice crystals within cumulonimbus clouds.
What is hail?
The type of front where a warm air mass slowly moves above a cold air mass.
What is a warm front?
A region of Earth's Stratosphere that absorbs most of the Sun's UV radiation and protects us from extreme temperatures from the sun.
What is the ozone layer?
The process by which water vapor cools and condenses.
What is condensation?
The tool that measures air pressure.
What is a barometer?
High altitude, flying, inflatable meteorology tool that uses scientific instruments (radio-sonde) to collect various weather data.
What are weather balloons?
When a warm air mass and a cool air mass push against each other and neither moves. This can last for days.
What is a stationary front?
The measure of force with which air particles push on matter.
What is air pressure?
These clouds that are white, "puffy" or "cotton-like" in appearance, and can join with other ones. They significy fair weather.
What are cumulus clouds?
Two (2) reasons the midwest is known for extreme hail and tornadoes.
What is?........
- Flatter, higher elevation
-Consistent winds from the south (Gulf of Mexico) & north (North pole area).
- That area of land warms quickly in the spring causing warm air masses (through radiation and conduction.)
-Location is just east of Rocky Mountains, causing cool, dry air to come directly into that area.
-the Coriolis Effect causes winds to blow and converge in this area.
The type of energy transfer where heat & light energy travel through space and are absorbed (or reflected) by various types of matter.
What is radiation?
When a cold front moves upon a warm front and pushes the warm air mass higher into the Troposphere.
What is an occluded front?
When warm air rises in the Troposphere (because it's less dense), cools off (becomes more dense) and then sinks back down to the surface of the ground.
What are convection currents?
Thin, feathery clouds that form high in the atmosphere and are composed of ice crystals.
What are cirrus clouds?
It describes the constant air currents around the Earth (at various latitudes) that shift direction or curve because the Earth rotates.
What is the Coriolis Effect?
Weather that occurs over long periods of time.
What is climate?
The type of front that is associated with extreme weather.
What is a cold front?
It usually moves from areas of high pressure to areas of low pressure.
What is the wind?
Pure, condensed water that exists higher in cumulonimbus clouds in below freezing temperatures. It aids in the production of larger hail.
What is super-cooled water?
Name three (3) factors that affect our weather.
What is ?
-temperature
-air pressure
-humidity
-wind speed and direction
-precipitation
Radiation, conduction, and convection.
What are types of heat transfer?
