What da?
The scientific study of the atmosphere.
What is meteorology?
The instrument we use to measure air pressure.
What is a barometer?
Any form of water that falls to the earth's surface.
What is precipitation?
The Law of the Winds.
What is air always moves from areas of high pressure to areas of low pressure?
One example of a low cloud.
What is stratocumulus, stratus, or nimbostratus?
An indication of the amount of thermal energy in the air.
What is temperature?
Moving air.
What is wind?
A measure of the amount of invisible water vapor in the air.
What is humidity?
Three factors that determine wind speed and direction.
What are pressure effects, the Coriolis effect, and friction effects?
What are altocumulus and altostratus?
The two most common temperature scales.
What are Fahrenheit and Celcius?
The two aspects of wind we want to know.
What is wind direction and wind speed.
The ratio of the amount of water the air does hold to the amount of water it can hold at that temperature.
What is relative humidity?
Another term for fluid friction.
What is drag?
Three examples of high clouds.
What are cirrus, cirrocumulus, and cirrostratus?
The weight of atmospheric gases on the earth's surface; measured in units of force per unit of area.
What is atmospheric pressure?
The instrument used to measure wind speed.
What is an anemometer?
The instrument used to measure humidity.
What is hygrometer?
These get their name because they helped the sailing merchant ships on their way from Europe to North and Central America.
What are trade winds?
The temperature of a parcel of air at which the relative humidity is 100%.
What is dew point?
Normal sea level air pressure is this. This is a 500 point question after all...
What is 14.7 psi or 101,325 Pa?
The lowering of felt air temperature as wind blows over unprotected skin.
What is wind chill factor?
These send out microwave radio signals to measure precipitation in storms. They can also measure wind speed, providing valuable information about approaching severe weather.
What are modern Doppler weather radars?
Zones of high pressure caused by descending air at 30o latitude (either north or south).
What are horse latitudes?
What is freezing rain, sleet, hail, and snow?
