Weather Patterns Pt 2 Flashcards
Cold font
Cold air forces warm air to rise and makes a sudden weather change
Warm font
Warm air moves over cold air and produces poor weather for several days
What represents cold/warm fonts
Cold font- triangle
Warm font- half circle
After a font passes an area
Clear skies
Weather station circles
Wind direction, wind speed, cloud coverage, temperature, and air pressure
Low pressure areas
High pressure area
Low pressure- stormy
High pressure- clear
What are clouds made of
Liquid or solid water cooling on particles in the atmosphere
Precipitation
Rain sleet freezing rain snow and hail
Tornados
Form on land last for short period of time and smaller then a hurricane
Hurricane
Form on warm water last for several days and larger then tornados
As altitude increases air pressure?
Decreases
Warm air rises because
Low Air pressure and low density
Cold air sinks because
High air pressure and high density
As temp increases density and air pressure ?
Decreases
Changes in air pressure cause the
Wind
