Document Summary

General circulation of the atmosphere- fronts: fronts sloping surfaces separating air with different temperatures and moisture, can trigger severe weather and violent storms, cold fronts: cold air masses moves under warm air, lifting it up. Vertical storm clouds, heavy rain and snow, and thunderstorms can happen: warm fronts: warm air flows up over cold air and results in widespread clouds and rain over a large area. Mid-latitude cyclones: a cyclone in the northern hemisphere rotates counterclockwise air in low pressure that can present at large, medium, or small scales, at the medium scale, cyclones form individual thunderstorms, at the small scale, cyclones form tornadoes. 1: horizontal wind shear (wind shifts from head winds to tail winds, two types of thunderstorms, air-mass thunderstorms most common and result from air convection. Flow at low latitudes and tend to form in late afternoons during summers at mid-latitudes: super cell thunderstorms frontal collision of air at mid-latitudes.
