Climate from an astronomical perspective

The climate conditions of each planet ,apart from size,composition and distance from the Sun is due to inclination. The greater degree in inclination the more atmospheric conditions change across latitudes. -

For instance, Jupiter's inclination compared to that of Uranus creates really different weather conditions where Jupiter has atmospheric condition similar to areas around the Earth's Equator where nothing really changes over the course of a year whereas conditions across latitudes on Uranus are those similar to those in Arctic regions where changes are extreme every 6 months where long periods of constant daylight are replaced by long periods of complete darkness.

If the Earth had the inclination of Jupiter then there would be very little difference in daylight/darkness across all latitudes whereas if the Earth had an inclination like Uranus there would be huge swings in daylight/darkness differences every 6 months and most locations across latitudes would experience conditions like those within the Arctic circle in these terms.



Mercury/ Venus/ Jupiter - Countries around the Equator

Earth/Mars/Saturn/Neptune - Countries at mid-latitudes

Pluto - Northern latitudes like Mid- Scandinavia , Mid- Canada, Mid- Alaska

Uranus - Countries with towns inside the Arctic circle

This was in response to a question as to what climate planets would have if they were countries. Inclination is a baseline for that determination, at least for those who value their intelligence and astronomical challenges.
