Tools of Meteorology
What instrument do meteorologists use to measure temperature?
Thermometer
What causes wind?
Differences in temperature or pressure
Wind will always flow from areas of _______ to _______.
High pressure to low pressure
Region in which an air mass forms
Source region
Weather for a particular location at a particular time
Station model
What instrument do meteorologists use to measure wind speed?
Anemometer
High altitude, high velocity "rivers" of air in the upper troposphere are called?
Jet streams
Longer term, steady precipitation
These types of air masses tend to be warm.
Tropical
Weather forecast made by calculations
Digital forecasts
What instrument do meteorologists use to measure the upper atmosphere?
Radiosonde (weather balloon)
What causes winds to rotate on Earth?
Coriolis Effect
What type of weather does a stationary front produce?
Very long term cloudy or rainy weather
These types of air masses tend to have high water content.
Maritime
Analog Forecasts
What instrument measures humidity?
Hygrometer
Which wind system affects the mid-latitudes?
Westerlies
What kind of front can produce severe weather due to several different air masses mixing in a small area?
Occluded front
These air masses tend to have little water content.
Continental
Barometric pressure
What effect of physics enables weather radar to determine how fast a storm is moving towards or away from a weather station?
Doppler effect
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.
What kind of weather would you expect to get under a high pressure system?
Clear and dry
What is the term for when an air mass moves into a new region and changes or is changed by the climate in that area?
Air mass modification
Where the lines will be closest together
