I decided to make a game called What Plants Crave.  It’s a plant growth simulator.  So far I’m just working on the statistical modeling.

I’m happy with the weather modeling.  Here’s what I came up with:

1. My code starts with a base 50% chance of rain.
2. Every day it doesn’t rain, the base chance increases 20%.
3. If it rains, the amount of rain is determined by the chance of rain on that day, multiplied by a random number between 0-1.
4. Every day it rains, the chance of rain halves.

Simple, elegant, works pretty good!

I live in Ohio, and to check the reasonableness of the sim-weather, I looked up our annual rainfall.

According to this we get around 30″-40″ of rain annually.

My sim-weather reliably puts out around that much!
