/* An attempt at a new weather handler for Discworld.
* Ceres@Discworld 14/4/96
*
* Having thought about the way weather works (and Discworlds interesting
* meteorology) I decided not to try and implement some model of realworld
* weather. Instead regional variations in weather are handled by
* regional climate properties. This system will handle diurnal and seasonal
* variations and that's about it. Hopefully that will make it more
* understandable, usable and efficient.
*
* Basic Operation
* ---------------
* The weather is based on weather 'pattern's. The pattern lasts for several
* hours and is calculated from the 'seasonal' norm and the 'variance'. The
* 'current' weather will tend towards the pattern weather. The actual weather
* in a room will depend on the current weather, local modifiers
* (climate property), diurnal variations and variance.
*
* Thus update_patttern() is called once every reboot (for the moment) and
* update_weather() is called every 5 minutes (UPDATE_SPEED).
*
* Decisions
* ---------
* Calculation of the general weather has been moved into
* update_weather. Rather than doing it on a room by room basis everytime
* someone looks! Instead, local climate controls will be added verbatim to
* the current global weather. This will improve efficiency massively, but will
* reduce the overall weather variations.
*
* Principles
* ----------
* Temperature should go down during winter and during the night.
* Clouds should increase during the winter.
* Wind should be higher during autumn and winter (I guess).
* Rain/sleet/snow will depend on cloud density and temperature.
* If it's windy and lots of cloud density we might get a thunder storm.
* Cloud cover should lower temperature as should wind.
*
* Changed Jun 3 1996 by Grampa to include weather notifications for rooms.
