100

Region in which an air mass forms

Source region

100

Weather for a particular location at a particular time

Station model

What instrument do meteorologists use to measure wind speed?

Anemometer

200

High altitude, high velocity "rivers" of air in the upper troposphere are called?

200
What kind of weather would you expect to get from a warm front?

Longer term, steady precipitation

200

These types of air masses tend to be warm.

Tropical

200

Weather forecast made by calculations

Digital forecasts

300

What instrument do meteorologists use to measure the upper atmosphere?

Radiosonde (weather balloon)

300

What causes winds to rotate on Earth?

Coriolis Effect

300

What type of weather does a stationary front produce?

Very long term cloudy or rainy weather

300

These types of air masses tend to have high water content.

Maritime

300

Analog Forecasts

400

What instrument measures humidity?

Hygrometer

400

Which wind system affects the mid-latitudes?

Westerlies

400

What kind of front can produce severe weather due to several different air masses mixing in a small area?

Occluded front

400

These air masses tend to have little water content.

A station model has a number of 993 in the upper right corner. What does this number measure?

Barometric pressure

500

What effect of physics enables weather radar to determine how fast a storm is moving towards or away from a weather station?

Doppler effect

500

Describe how the global wind system helps create tropical rainforests.

Trade winds converge at the Equator, creating a band of low pressure, which causes rain.

500

What kind of weather would you expect to get under a high pressure system?

Clear and dry

Air mass modification

500
