Air masses can ____ as they move across the Earth. Interaction between the air masses and local geography and weather conditions can produce different _______ events.
Formed when warm humid air rises into an unstable atmosphere and produce thunder and lightning along with wind gusts, rain, or hail.
Tornadoes represent? How are they formed?
Small regions of extremely low pressure.
When wind speed at the ground is slower than upper wind speed and updrafts are created
How can the possibility of a tornado be predicted? (5) =?
temperature, barometric pressure, wind speeds, directions, and radar echoes. Tornado watch
How are hurricanes rated and on what scale?
based on pressure and wind readings on the Saffir Simpson scale.
When is the rating of hurricanes taking place?
during the progression of a tropical depression to a tropical storm to a hurricane.
Damage from a tornado vs a hurricane
Tornado: Wind damage. Hurricanes: High winds, large amounts of rainfall and flooding due to high ocean waves (storm surge)
Climate system involves 5 areas?
atmo, hydro, geo, bio, and cryosphere ( region covered with ice or snow)
5 categories within the Koppen classification

humid middle latitude with mild winters?
Mild winters. Avg temp of coldest month is below 18 C and above -3.
humid middle latitude with severe winters?
