For us humans, Spring, Summer, Autumn, and Winter are taught to us at school and is usually seen from astronomical standpoint. In reality, we humans know better that there isn't just the traditional four seasons, meteorologically speaking. There's the wet/monsoon season and the dry season in the tropics and subtropics, "fire season" in places where forest fires is unavoidable, polar night and day around the Arctic and Antarctic, and so forth. Let's not even get started on why not all calendars match up to the temperatures!
Your challenge for September: Give us a look at a canon Transformer's perspective(s) on the shift from the various seasons. How would those that don't mind organic life try to explain the concept, symbolism, what-have-you, to those that could probably care less, or have difficulty grasping the influence from the Earth's tilt? A Transformer who's used to Spring in April while living in the Northern Hemisphere, now experiencing Autumn in the Southern Hemisphere during that same month? Toss in Stonehenge if you have to!
G1, Animated, Beast Wars, Armada, IDW-verse, take your pick! Just remember to keep it family friendly!
An entry thread will be up later in the month.
