Alabama Questions With Correct
Answers
Atmospheric disturbances - CORRECT ANSWER✔✔-storms: general
| | | | | |
characteristics: smaller then general circulations, migratory and
| | | | | | |
transient, relatively short duration (min, hr, days), relatively predictable
| | | | | | | | |
conditions.
Storm classes - CORRECT ANSWER✔✔-Midlat disturbances- contrasts of
| | | | | | |
tropical and polar air, pronounced seasons
| | | | | |
Tropical disturbances- generally monotonous weather, cyclones
| | | | |
Localized severe weather- can occur at many locations, short durations
| | | | | | | | |
Midlat cyclones - CORRECT ANSWER✔✔-Responsible for much midst
| | | | | | | |
weather cause ppt for much of the year. 35 to 75 degrees (Westerlies)
| | | | | | | | | | | | |
Forecasting weather, diameter of 1000 miles, low pressure (990-1000
| | | | | | | | |
mb), counter-clockwise circulation (N hemi), brings cold air from N and
| | | | | | | | | | |
warm from S, convergence
| | |
,Movement - CORRECT ANSWER✔✔-3 elements, major disturbance in
| | | | | | | |
the westerlies, cyclonic wind circulation, cold front advances faster than
| | | | | | | | | |
warm
Life cycle - CORRECT ANSWER✔✔-Cyclogenesis: birth of a cyclone
| | | | | | | |
Origin to maturity in 3-6 days, begin as waves among polar front,
| | | | | | | | | | | |
contact of cold and warm air, relationship between upper and lower air
| | | | | | | | | | | |
flow, zonal: not active, meridional: is active.
| | | | | |
Occlusion - CORRECT ANSWER✔✔-The last stage, occluded front,
| | | | | | | |
generally intense ppt for a short period until all warm air is aloft,
| | | | | | | | | | | | |
weakens the low pressure center, dissolves
| | | | |
Occurrence and distribution - CORRECT ANSWER✔✔-In N semi 6-15
| | | | | | | | |
occurring at all times, more abundant, stronger, and faster in winter
| | | | | | | | | | |
than summer, follow movement of sun
| | | | |
Midlat anticyclones - CORRECT ANSWER✔✔-Diverging air, no fronts,
| | | | | | | |
clear and dry weather, strong winds, may stagnate and remain in a
| | | | | | | | | | | |
region
Naming - CORRECT ANSWER✔✔-When a depression becomes a storm it
| | | | | | | | |
is named (alphabetical list), tracking centers (miami, honolulu, guam),
| | | | | | | | | |
names are re-used unless notable
| | | |
, Classification - CORRECT ANSWER✔✔-Based on wind speed, tropical
| | | | | | | |
depression: less than 33 knots has a closed wind circulation pattern.
| | | | | | | | | | |
Tropical storm: 33 to 63 knots. Hurricane: greater than 63 knots.
| | | | | | | | | |
Minor tropical disturbances - CORRECT ANSWER✔✔-Easterly waves:
| | | | | | |
long, weak, low pressure system 5 to 30 degrees, oriented north to
| | | | | | | | | | | |
south, 100s of miles long
| | | |
Major tropical disturbances - CORRECT ANSWER✔✔-Intense, low
| | | | | | |
pressure disturbances, develop on tropics, hurricanes, typhoons,
| | | | | | |
cyclones, smaller than midst cyclones, 100-600 miles wide
| | | | | | |
Characteristics (hurricanes) - CORRECT ANSWER✔✔-Prominent low
| | | | | |
pressure centers, steep pressure gradients, strong winds, spiral inwards,
| | | | | | | | |
warm, moist air (energy), same basic pattern of low pressure, just
| | | | | | | | | | |
intense
Hurricane eye - CORRECT ANSWER✔✔-Non-stormy, diameter of 10-25
| | | | | | | |
miles, height of 10 miles, eye wall, rising air (updrafts), high speeds, ppt,
| | | | | | | | | | | |
Downdrafts in eye ( no clouds of ppt)
| | | | | | | |
Hurricane origin - CORRECT ANSWER✔✔-Only form over warm oceans
| | | | | | | | |
in tropics: water temp over 80 to a depth of 160, coriolis is minimal at
| | | | | | | | | | | | | | |
equator, so form less than 10 lat (poleward of ITCZ) not always
| | | | | | | | | | | |
