Complete Solutions.
Air mass - ANSWER large region of air with same temperature and humidity (5 types)
cA - ANSWER continental arctic; polar high/cold and dry
cP - ANSWER continental polar; polar high/cold and dry (in winter)
mP - ANSWER maritime polar; polar high and sub polar low/cold and humid
cT - ANSWER continental tropic; subtropical high/hot and dry (in summer)
mT - ANSWER maritime tropic; ICTZ and subtropical high/warm and humid
thunderstorm - ANSWER cumulonimbus cloud with lightning and thunder (3 types)
single-cell thunderstorm - ANSWER forms in maritime tropical air mass/most frequent in late afternoon
when unstable air parcels exist/mild short storm with weak wind shear
multicell thunderstorm - ANSWER forms on fronts (between air masses)/severe weather, squall lines,
moderate wind shear/system lasts hours
supercell thunderstorm - ANSWER forms in humid air and strong wind shear (Great Plains)/most
powerful and makes tornadoes/least common
single cell life cycle - ANSWER cumulus, mature, dissipating

Complete Solutions.
cumulus stage - ANSWER 1st stage of single cell cycle--cumulonimbus forms in updraft (warm, upward
air), reaches dew point and latent heat releasing into cloud, warming and rising
mature stage - ANSWER 2nd stage of single cell--strong updrafts and rain makes downdrafts, upper
regions become glaciated which leads to lightning, thunder, rain, hail
dissipating stage - ANSWER final stage of single cell--downdrafts and net evaporation cause weakening;
downdrafts block updrafts and evaporation
hurricane stages - ANSWER tropical disturbance, tropical depression, tropical storm, hurricane
tropical disturbance - ANSWER 1st stage of hurricane--mass of thunderstorms on tropical wave
tropical depression - ANSWER 2nd stage of hurricane--wind increase and closed rotation because of
Coriolis force
tropical storm - ANSWER 3rd stage of hurricane--winds increase 39+ mph and storm is more organized
hurricane stage - ANSWER final stage--storm organized with well defined rain bands and winds 119+
mph
positive feedback - ANSWER feedback of storm in which more moisture leads to latent heat being
released and storm gets stronger with high wind speeds as a result
sea spray - ANSWER frothy ocean waves that evaporate and increase air moisture, from positive
feedback
indian ocean - ANSWER most dangerous area for hurricanes due to large populations at sea level near
coasts
