Discussion Overview

The discussion centers on the availability of information and global maps depicting the direction and speeds of prevailing winds in the mesosphere. Participants explore various resources and tools for accessing this data, while also addressing the challenges associated with obtaining such information at high altitudes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests global maps of prevailing winds in the mesosphere, expressing difficulty in finding relevant sources.
  • Another participant shares a link to a global wind map but notes that it only covers altitudes up to 10 hPa, which is below the mesosphere.
  • A third participant reiterates the limitation of the provided tool, indicating it does not reach the required altitude for mesospheric data.
  • Some participants suggest searching for scholarly articles on prevailing mesospheric winds, indicating that most available resources are models rather than direct measurements.
  • One participant mentions the Laboratory for Atmospheric and Space Physics (LASP) as a potential source for mesospheric wind information.
  • There is acknowledgment that prevailing winds in the mesosphere may not be as well-documented or accessible as those at lower altitudes.

Areas of Agreement / Disagreement

Participants generally agree that finding comprehensive data on prevailing winds in the mesosphere is challenging, and multiple competing views exist regarding the availability and nature of such data. The discussion remains unresolved regarding specific resources that provide the desired information.

Contextual Notes

Limitations include the lack of direct measurements at mesospheric altitudes and the reliance on models that may not fully represent prevailing wind patterns. The discussion also highlights the potential for paywalled resources that may contain relevant information.

Hi! Please, does anyone know where could I find information or (ideally) global maps with the direction and speeds of the prevailing winds in the mesosphere (if any)? As much as I've tried to, I've been unable to find any source providing this information. Thank you in advance!

This is a global map of wind, weather and ocean conditions. You can choose the global projection and the height of the winds in terms of hPa. I'm not sure it has coverage that high up, but it might.
Thank you very much, CapnGranite. This is certainly a great tool, but unfortunately it only reaches a height of 10 hPa, which is approx. 30 km, well below the stratopause and the mesosphere. :frown: I need to go higher...

Yes, I did that, but I'm still unable to see a worldwide map of prevailing directions/speeds (like the one CapnGranite provided for lower altitudes, if not necessarily so sophisticated.) Maybe it's just me being unable to interpret these data, but I "can't see" the mesospheric winds from point A to point B.

To put it in other words: an atom of nitrogen right now 75 km above Manhattan (or Managua, or Madrid, or Madagascar...), where will it tend to be tomorrow (or in a week)?
 
Not simple. AFAICT, there really are none like what occurs down lower.
Example: This is behind a paywall but does present 'prevailing winds' in a model: http://link.springer.com/article/10.1007/s00585-000-0300-y

If you use google scholar and ' prevailing mesospheric winds' you get hits. Most appear to be models. You decide what fits your needs.
 
You might see what the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder might have.

Thank you both very much. I'll try and see if I can get a general idea of the "mesospheric circulation"...
