The nature of the distributions and some basics are described in

I have used them for generating point patterns, adding 'noise' to generated elevation surfaces, simulation of occurrences of phenomena in space and/or time.  Distributions of various types form the foundations of statistical testing and in inferential statistics you are often comparing observations to those of a known distribution.  Understanding them, might be easier if you had a particular application in mind.
