< p >地球有三个对流细胞/半球。这些都是极细胞,套圈细胞和哈得来环流圈。These create the trade winds, westerlies and polar easterlies which control many aspects of climate, such as where rain shadows & dry zones are located and where ocean currents flow.
However, if you were to slow down the rotation rate of a planet, you could turn those three convection cells into a single, gigantic convection cell. Assume a roughly Earth-like planet in all characteristics (sans rotation rate, which is slowed down in order to turn the three convection cells into one - and apparently axial tilt might have an effect, I'm not sure). Because climate is a combination of multiple factors, there are several questions to consider:
- How would the movement of oceanic currents be affected?
- In what direction would the wind blow at different latitudes of the planet's surface?
- Where would the dry zones of the planet be? The wet zones?
- Where would the hot zones of the planet be? The cold zones?
Bonus:
- How would this affect violent weather phenomena such as hurricanes and tornadoes?
