GY 101 Lab Final Exam
percent of H2O in the atmposhere
0-4%
percent of N in the atmosphere
78.08%
classification for Southeastern United States
Cfa
where are the driest climates?
at 30 degrees N and 30 degrees S
what does it mean when trees do not have wide rings?
atmosphere was not conducive to growth (drought, forest fire, flooding, etc)
what does it mean when trees have very wide rings?
atmosphere was very conducive to growth (precipitation, temperature)
in a climograph, should the precipitation be portrayed as a line or bars?
bars
where are the wettest climates?
by the equator
Hadley Cell
causes the desert because of the descending air; 30 degrees N and S
B
dry
nitrogen oxygen water argon carbon dioxide
gases in the atmposhere
H
highland
a
hot summer
postive anomaly
indicated that the observed temperature was warmer than the reference value
negative anomaly
indicates that the observed temperature was cooler than the reference value
tornado watch
issued several hours ahead of expected severe weather; identified as having severe thunderstorm outlooks; issues when conditions are favorable for tornadoes to form
tornado warning
issues when there are tornadoes occurring; a tornado has been caught by a radar or has actually been seen by someone on the ground; typically issues for very small areas, such as counties
in a climograph, should the temperature be portrayed as a line or bars?
line
T=2
means it happens more than once a year
T=1
means it happens once a year
T=0
means it never happened before
C
mild mid latitude: mild winters, warm/hot summers
tornado season
most frequent and strongest in the spring in the southeast
Green House Effect
need to sustain life on earth; earth would freeze every night without it
what is the most abundant permanent gas?
nitrogen
why is there a huge desert in Africa?
on poleward side you have descending air, hence why you see on 30 degrees South and 30 degrees North there are huge deserts (Australia and Africa)
E
polar: very high latitude, cold climate
why is there so much rain around the equator?
rising air
D
severe mid latitude: severe, cold winters
dendrochronology
the science of technique of dating events, environmental change, and archaeological artifacts by using the characteristic patters of annual growth rings in timber and tree trunks
1950
the year reliable tornado records began to be kept
what causes the tropical climates to be wet?
tropical zone of convergence--convection
A
tropical: low latitude, warm and wet
what is an example of dendrochronology?
using tree rings to try and date climate in the distant past
what is the most abundant variable gas?
water vapor
f
wet all year
