-
calendar [x] calendar split into months based on year and day length [ ] each planet has a calendar
-
seasons [x] zones of latitude [ ] dependent on axial tilt and rotational period (day) and orbital period (year) [ ] each hex has metrics that are dependent on the month [ ] each hex may have different seasons [ ] a group of hexes that have a similar seasonal cycle make up a "seasonal zone"
-
water cycle [x] ground water: aquifers [x] surface water: lakes and rivers [ ] seasonal rainfall

[ ] each hex has a wind speed and hex direction [ ] wind speed: higher in ocean hexes than land hexes. Proportional to planet atmospheric pressure and average surface temperature [x] wind direction: dependent on prevailing wind pattern [x] calculating wind direction - wind goes from high pressure to low pressure cells - hex wind direction will point towards neighbor with lowest atmospheric pressure - groups of similar pressure are "cells" [x] calculating hex pressure - higher pressures on Tropic of Cancer (northern) and Tropic of Capricorn (southern) and polar regions - lower pressures on equator and between the tropics - lower pressure in higher elevations - dry air is more dense than moist air - cold air is more dense than warm air [ ] impact on rainfall: (ex: amazon rainforest) wind directed from an ocean hex onto a land hex = increase in moisture proportional to the change in elevation between this ocean hex and the land hex 5 hexes away in the same direction. [ ] impact on fertility wind from a desert area will increase fertility of land it reaches [ ] impact on temperature wind directed from an ocean hex onto a land hex increases its temperature and that of its inland neighbors proportional to the wind speed and latitude.

geography [ ] detect oceans [ ] detect inland seas [ ] detect lake systems [ ] detect mountain ranges [ ] detect glaciers [ ] detect peninsulas [ ] detect islands [ ] name all of the above

new generator architecture [x] use numpy [ ] store all values of a hex in fixed numpy arrays "value array" in the grid instance, use getters and setters to access each value without having to rewrite a lot of code [ ] use transform functions instead of putting everything in mapgen.py
