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.

Parameters for this behavior

Parameter nameDescription
Precipitation Change - B "B" in the function for varying precipitation through time.
Precipitation Change - C "C" in the function for varying precipitation through time.
Precipitation Change - Precip Lower Bound The lower bound for allowed precipitation values.
Precipitation Change - Precip Upper Bound The upper bound for allowed precipitation values.

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.

You can set bounds on the possible precipitation values using the Precipitation Change - Precip Lower Bound and Precipitation Change - Precip 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 Temperature Climate Change behavior. You do not need to assign this behavior to trees.
