ERTH 335 - Exam 2 Questions With Correct
Answers.
Why do scientists use climate models? - answer✔1. to understand present climate
2. tool to run experiment
3. to understand future climate
4. to communicate scientific understanding
Describe the basic strategy used in climate models to calculate future climate conditions -
answer✔divide earth into small grids and use equations to simulate wind, radiation, and
variability
How did we calculate future climate using the human climate model? - answer✔old
temperature + greenhouse warming (0.1 celsius) + random variability (coin flip) + (velocity*ΔT)
ΔT = neighbors temp - your temp
In the human climate model, why did you have to talk to the person next to you in order to
calculate future climate in your grid box? - answer✔Simulates how wind patterns affect
temperature

i.e. in the climate model a temperature found in one grid, moves to the right after a few time
steps, mimicking how heat is exchanged when the wind picks up and transfers this air
What, in the Human Climate Model, could you calculate without talking to the person next to
you? - answer✔the future climate influenced by greenhouse warming and variability (excludes
wind patterns)
What processes in the Human Climate Model were realistic? - answer✔- effect of wind to
temperature
- general climate in certain regions
- simulates variability
What to improve on Human Climate Model? - answer✔- 2 dimensional winds instead of 1
dimensional
- vertical structure (using info from the person in front of you as well)
- winds that change with time
What processes dominate the evolution of climate models over short timescales (hours to
days)? - answer✔winds
What processes dominate the evolution of climate models over long timescales (decades to
centuries)? - answer✔global warming
