Mature-precip

wind shear, turbulence, lightning, tornadoes, icing


What is a microburst - CORRECT ANSWER- 10-15 min of downdrafts from a thunderstorm
that can cause low level wind shear


Types of clouds associated with thunderstorms - CORRECT ANSWER- Towering cumulus,
cumulonimbus, cumulonimbus mammatus


4 types of fog and how they form - CORRECT ANSWER- Upslope- Warm moist air forced
up in altitude and cooled and fall back down mtn as fog
Radiation- warm air mass cools to dewpoint at night
Precip-accompanies rain showers and steady rain
Advection- warm moist air moves over colder land mass or cold air moves over warm body
of water


When and how fog types dissipated - CORRECT ANSWER- Upslope-wind reduced or
moving air has little moisture
