Continental Tropical Air Mass
This air mass is warm and dry, forming over land in tropical regions.
Match each atmospheric layer with what happens in it.
TRIPLE POINTS!!
Troposphere → Weather
Stratosphere → Ozone
Mesosphere → Meteors
Thermosphere → Aurora
Exosphere → Satellites
How can meteorologists predict the weather?
Using data from satellites, radar, and weather stations. They analyze temperature, humidity, and wind patterns, and use computer models to forecast what will happen.
