Welcome to the Ask Me Anything (AMA) community! This is a space where individuals from various backgrounds come together to engage in open and informative discussions. To ensure a respectful, enjoyable, and inclusive experience for everyone involved, we have established the following rules and guidelines:

  2. Practice Politeness and Courtesy:

    • Use polite and considerate language when asking questions or engaging in discussions.
    • Be patient and understanding if the person answering takes time to respond. They may receive a high volume of questions.
    • Avoid spamming or repeating the same question multiple times. Give others a chance to ask their questions as well.

-Use NSFW and trigger warning TW in brackets if you talk about sensitive subject.

  1. Respect Boundaries and Privacy:

    • Do not ask personal or invasive questions unless the participant explicitly invites such queries.

    • Ensure your questions are relevant to the participant's expertise or field of knowledge.
    • Avoid posting low-quality or repetitive questions that add little value to the discussion.
    • Respect the purpose of the AMA and avoid using it solely for self-promotion or advertising.

    • Prioritize thought-provoking and insightful questions that foster engaging conversations.
    • Be open to different perspectives and use the AMA as an opportunity to learn and broaden your understanding.

in the future, a mod check and balance system might be implemented . Subject to change : [You might appeal your ban by contacting a special appointed moderator to judge if the ban was abusive.

Special appointed mod can create jury like conversation with randomly chosen users with jury votes to decide if bans are legit or not.]

MODERATORS
 

cross-posted from: https://discuss.tchncs.de/post/479621

Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are:

  • computation fluid mechanics
  • scientific programming and HPC
  • nonlinear shallow water equations
  • statistical description of turbulence: spectra, energy budget etc.
  • experimental methods: PIV
  • stratified turbulence
  • academia
  • navigating your career pre- and post-Ph.D.

Ask away!

Not just the Gulf stream, but the whole Atlantic Meridional Overturning Circulation (AMOC). AMOC, as you may know transports heat keeping the tropics cool, north warm and melting the Arctic. From what I understand the observations are only a few decades old, but it suggests the AMOC has been slowing down.

As an extreme case (and I repeat extreme) scenario it begs the question would it shut down or flips direction. Theoretically there are "thermohaline" circulation modes where that may happen. Paleoclimate evidence suggest that there were times that there was no AMOC and we had a PMOC (a Pacific one) instead. So many open questions...
