8-4 Weather maps & Weather prediction Virtual Lab
1.
Scientists who study weather processes & patterns are called
_____________________. They use data to predict the weather.
2. Weather maps show what conditions are like over a large area. They
help us identify weather patterns and make forecasts Label each type
of map & its uses.
a. Type: _______________________
b. Isobars connect locations with the same
_________________
c. In High pressure areas, _________ air
sinks, bringing ______, __________ weather.
d. Low pressure areas, warm air __________
& cools, forming _______________ &
_______________ weather.
a. Type: _____________________________
b. Isotherms connect places with the same
____________________ (color map)
a. Type: _____________________________
b. Uses _______________ to send out
_____________ waves that bounce off
clouds.
c. Can detect the _______________,
_____________, & type of ______________
3.
Fronts – the _______________ _____________ large moving air masses.
Fronts are where cold and warm air masses collide. Fronts bring a change
in weather.
a. _________ front.
-Warm, wet air __________ rises over a
_________ air mass.
-As warm air rises, it cools & forms
___________ that bring light ________
b. _________ front.
-Warm air rises & cools ___________,
forming large clouds
-This bring heavy ___________ &
_________
-Storms usually pass ____________
c. ________________________ front.
-2 air masses meet & _________ moving.
-warm & cool air mix forming clouds
-Can produce light rain over _________
________ until the front begins to
________ again.
d. ________________________ front.
a. Type: _____________________________
b. “see” the clouds in _____________ light &
_______________________ light.
c. Show ___________ cover, cloud
_________________, & ________ _________
in the atmosphere.
-Cold front ____________ up to a warm
front
-Cold air lifts warm air which typically brings
precipitation from __________________ to
____________ rain.

4.
Measures Wind Direction.
As wind blows, the vane turns so that it points in
the direction that the wind is blowing from.
a. Weather maps help you make forecasts by tracking weather patterns
b. Fronts bring _____________________, such as rain or snow
c. If a front is ___________________ you know that precipitation is
_____________
5.
Measures Air Pressure
When atmosphere contains more air molecules in
a given amount of space the air pressure increases.
