Probability Distributions

 

Aim (why are we doing this?): We have a record of some climate variable, and want to know: How often do we get months which are hotter than 30$^\circ $C? Or: How often do droughts recur? In order to answer this, one may look at the distribution of the temperatures or rainfall: how many times have the events happened before?

Probability distributions and density functions describe the observed or expected frequency that a value has taken/will occur.
