CLIMATE physics-general atmospheric circulation

Click For Summary

Homework Help Overview

The discussion revolves around understanding the general circulation patterns of the atmosphere on different types of planets, specifically focusing on the effects of rotation speed. The original poster seeks sketches that illustrate these patterns for slow rotating, fast rotating, and non-rotating planets.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the impact of the Coriolis effect on wind patterns, particularly how rotation speed influences air movement at different latitudes. Questions arise regarding the behavior of winds at 45 degrees latitude under varying rotation speeds.

Discussion Status

The discussion is active, with participants exploring different aspects of atmospheric circulation. Some guidance has been offered regarding the Coriolis effect, and there is an ongoing inquiry into the behavior of winds at specific latitudes. Multiple interpretations of wind behavior are being considered.

Contextual Notes

Participants express difficulty in finding relevant literature on the topic, indicating a potential gap in available resources for further exploration.

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?
