I think it would be conventional to have both Solstice & Equinox change the terrain of plains, grasslands, swamps, deserts, forests etc... during these celestial events in the year. An equator, tropic of Cancer, tropic of Capricorn, arctic circle and antarctic circle would represent circumferential lines running across the map horizontally. After the discovery of say, "Meteorology" in the modern age would these changes on land take place.
I'm not sure if this idea has been suggested before I think it would realistic to implement. Remember the plan of attack for the Iraq war had to start before the summer or else it would have been too hot. Cold & hot weather should have an affect on combat.
