This question is in reference to a previous question by TrEs-2b and SRM: I want to create a planet with a significantly longer day than Earth's. However, I was only able to find a question about a planet with 9-year long days. This is way too long of an rotational period. As evidenced by the linked question, longer days equal more extreme weather (high winds, rainfall, different hemispheres). I am looking for weather like this, but do not want the distinct hemispheres (one super hot and one super cold).
So, what would be the range of day lengths needed to achieve extreme weather without distinct hemispheres?
Clarifications:
- The planet in question is just slightly larger than Earth
- There is one super-continent, similar to the size and shape of Pangaea, in the middle of the planet surrounded by oceans
- Everything else is identical to Earth (atmosphere, pressure, etc.)
- I am looking for the minimum day length to achieve extreme weather and the maximum before the distinct hemispheres form
- What I mean by distinct hemispheres is that the only habitable space is in the middle. Polar regions and deserts are ok.
Bonus points if the orbital period around the pseudo-Sun is one "day," like if the day length is equivalent to 400 Earth days, then it takes 400 Earth days to complete a full orbit.
