Temperature Climate Change

This behavior changes the value of the Mean Annual Temperature parameter of the SORTIE plot. This can be used to simulate the effects of climate change. If the run does not have a behavior that uses temperature, this will have no effect.

Parameters for this behavior

Parameter name	Description
Temperature Change - B	"B" in the function for varying temperature through time.
Temperature Change - C	"C" in the function for varying temperature through time.
Temperature Change - Temp Lower Bound	The lower bound for allowed temperature values.
Temperature Change - Temp Upper Bound	The upper bound for allowed temperature values.

How it works

The value for plot temperature is a function of time elapsed since the start of the run, as follows:

T = T₁ + B * t^C

where:

T is the mean annual temperature, in degrees C, at time t
T₁ is the mean annual temperature value at the start of the run, as assigned in the Plot parameters
B is the Temperature Change - B parameter
C is the Temperature Change - C parameter
t is the time elapsed, in years, since the start of the run

This value is then given to the Plot object which makes it available to other behaviors in the run.

You can set bounds on the possible temperature values using the Temperature Change - Temp Lower Bound and Temperature Change - Temp Upper Bound parameters. Values are not allowed to go outside these limits.

How to apply it

Add this behavior to the run. You can use it alone or in addition to the Precipitation Climate Change behavior. You do not need to assign this behavior to trees.
