General Science-Fronts & Clouds Flashcards
Differences in air pressure cause WHAT and WHAT of air masses of different temperatures toward each other.
Wind and Movement
When a warm air mass overtakes a cold air mass.
Warm Front
During a warm front, as the warm air advances; it rides over the cold air ahead. Is it heavier?
Yes
During a warm air front, as warm air rises what happens to the water vapors?
They condense into clouds that can produce rain, snow, sleet, or freezing-even all 4.
When a cold air mass overtakes a warm air mass, this is called a what?
Cold Front
What are cold fronts often proceeded by?
A Line of Precipitation, however sometimes they don’t produce precipitation as they move.
What is the only sign that a front has moved through your area?
Sudden change in winds and temperature.
When 2 fronts push against each other in a stalemate where nothing is displaced.
Stationary Front
What can Stationary Fronts often cause?
Cloudy, wet weather that can last a week or more.
What are the 3 main types of clouds?
Stratus
Cumulus
Cirrus
Clouds are low-hanging, broad, flat clouds that blanket the sky.
Stratus
The lowest of low clouds, when they occur on the ground are called what?
Stratus
Clouds are massive clouds that are puffy like popcorn with relatively flat bottoms and rounded tops.
Cumulus
When cumulus clouds darken, you can expect what?
Heavy Rain
When clouds are the thin, wispy clouds that occur much higher in the atmosphere, at elevations of 20,000 feet or more.
