Air Pressure
How much weight does air exert on our body, per square inch?
Approximately, 15 lbs per square inch
What is wind?
Air moving from a high pressure system to a low pressure system.
Dew needs what to form?
1. Water Vapor
2. Cooled Temperatures (above freezing
3. Nuclei
What is a front?
A boundary that exists between air masses of different temperature and humidity.
What are the three types of heat transfer?
Convection, Conduction and Radiation
What does Bernoulli's Principle State?
Moving air has less pressure than still air.
What slows wind down?
Friction, from objects on the ground.
Frost needs what to form?
1. Water Vapor
2. Nuclei
3. Freezing temperatures
Cold fronts usually bring what type of weather?
Stormy, cooler temperatures
The sun shining is an example of what type of heat transfer?
Radiation
What type of weather does a low pressure system bring?
Rainy, stormy weather
How is wind named?
Wind is named by where it comes from.
Hail Needs what to form?
1. Water Vapor
2. Nuclei
3. Super cooled temperatures (negatives)
4. Updraft
Warm fronts eventually bring what type of weather?
Warmer temperatures and eventually rain.
Water boiling is what type of heat transfer?
Convection
What type of weather, does a high pressure system bring?
Fair, nice weather
What does wind do for our weather?
Wind moves weather systems in or out of an area.
What does Nimbus mean in Latin?
Rain
What are two characteristics of cold fronts?
1. They move fast
2. They create cumulus clouds
Placing a iron pole in a fire would be an example of what type of heat transfer?
Conduction
What does a low pressure system mean?
There is little pressure on the layers of atmosphere. This allows stormy weather to enter the Troposphere.
What causes the Coriolis Force?
The bending of winds to the West
The Earth's rotation.
What three ways can clouds form?
1. Convection
2. Lifting
3. Frontal Activity
In a cold front, why does it create a storm system?
The cold air wedges under the warm air, creating a large cumulus nimbus cloud in a short amount of time.
Heat transfer is important to know for weather, because?
It shows us how heating occurs in nature, so we understand different heting processes.
