CLIMATE physics-general atmospheric circulation

[helpcometk]

Homework Statement

I'm trying to find sketches that demonstrate ,the general circulation patterns of the atmosphere and the cells in atmosphere of a planet.3 cases must be considered:a slow rotating ,a fast rotating and a non rotating planet.

Homework Equations

The Attempt at a Solution

It seems that corriolis effect has an impact and is related with the rotation speed.
Earth did not rotate, air flowing from a higher latitude toward the equator would move directly south or north (depending on the hemisphere). However, because of the rotation, air that flows toward the equator is moving from a latitude where its rotational speed is less to a latitude where the rotational speed is more. As a result, that air rotates more slowly than the land below it, so it "falls behind" and it is deflected toward the west .
This produces a wind at the equator that flows from east to west.
Likewise, air flowing away from the equator and towards a higher, more slowly rotating latitude will rotate more rapidly than the land below, and will deflect towards the east to produce a west-to-east wind.

That's fine for the winds at the surface near the equator. What about winds high aloft? What about winds at, say 45 degrees latitude? If the Earth was rotating very slowly, how would this change the answer to my question about winds at 45 degrees latitude?

at 45 degrees the winds would be deflected less i think if the planet was slow rotating.
Is there any book where i can look about this ,because i have searched in many and found nothing(peixoto,taylor,wallace)

Which way do the winds primarily blow in the middle latitudes?

This is known as the Coriolis effect and it plays a crucial role in shaping the general atmospheric circulation patterns of a planet.

For a slow rotating planet, such as Venus, the Coriolis effect would be less pronounced due to the slower rotation speed. This would result in weaker and less organized atmospheric circulation patterns compared to Earth. On the other hand, a fast rotating planet like Jupiter would experience much stronger and more complex atmospheric circulation patterns due to the stronger Coriolis effect.

In terms of the three cells of atmospheric circulation (Hadley, Ferrel, and Polar), the slow rotating planet would have weaker and less defined cells, with the Hadley cell being the most dominant. The fast rotating planet would have more defined and stronger cells, with the Ferrel cell being more prominent. For the non-rotating planet, there would be no Coriolis effect and therefore no distinct cells of atmospheric circulation. The air would simply flow from high pressure to low pressure areas, resulting in a more chaotic and unpredictable atmospheric circulation pattern.

Overall, the rotation speed of a planet plays a significant role in shaping its atmospheric circulation patterns, with the Coriolis effect being a key factor. Further research and analysis of atmospheric circulation patterns on different planets can provide valuable insights into the physics of climate and weather on these planets.
