Transcript of Friday, May 9 th, 2014 Endangered: Leatherback sea turtle (Dermochelys coriacea) Kingdom: Animalia...
Friday, May 9th, 2014
• Endangered: Leatherback sea turtle (Dermochelys coriacea)
• Kingdom: Animalia• Class: Reptilia• Order: Testudines• Family: Dermochelyidae• The leatherback is the largest, deepest diving,
& most migratory of all sea turtles. Adults can reach 4-8 ft & 500-2000lbs.
Do Now: May 9th
1. Describe what happens at a stationary front.
2. Compare & contrast cirrus & cumulus clouds.
3. You have plans to go surfing. Would you prefer a low pressure system or high pressure system? Explain why.
Do Now: May 9th
1. Describe a stationary front.– Wind/rain @ a stalled front – not moving
2. Compare/contrast cirrus & cumulus.– Cirrus: wispy, hair-like– Cumulus: fluffy, puffy, cotton– Both: fair weather clouds
3. You go surfing. Would you prefer a low or high pressure system? Explain why.
– High pressure system – pretty day– Low pressure system – winds = big waves

Station Models
Decoding Coded Pressure
196 Insert decimal point to left of last digit
19.6 Put a “9” and a “10” in front of result
919.6 1019.6Test results against range of normal atmospheric pressures
919.6 is below range of normal pressures…. REJECTED!
1019.6 is w/in range of normal pressures…. ACCEPTED!
Coded pressure 196= 1019.6 mb
Decode these coded pressures: 002 993 280 000
1000.2 999.3 1028.0 1000.0
Encoding the Pressure
1013.5 Remove decimal point
10135 Report last 3 digits
135
Pressure 1013.5 = 135 encoded pressure
Encode these pressures: 1032.7 987.3 1012.2 1000.1
327 873 122 001
The Barometric Trend+ 19 /
+ means “Higher now than it was 3 hrs ago”(- means “Lower now than it was 3 hrs ago”)
19 means pressure has changed by 1.9 mb
/ means pressure is currently rising( \ means pressure is currently falling)
What was the pressure 3 hours ago?
1017.7+1.9= 1019.6
1003.5-2.8= 1000.7
