State change behaviors act on the basic properties of the virtual plot being modeled.

State change parameters

Precipitation Climate Change

This behavior changes the value of the Mean Annual Precipitation 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 precipitation, this will have no effect.

How it works

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

P = P1 + B * tC

where:

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

How to apply it

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

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.

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 * tC

where:

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

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.
