      Does this (you having quantified the influence) mean that all weather forecasting models can/will have to be updated now?

    • @SimonClark
      @SimonClark  5 лет назад +5

      @@MrNicoJac fortunately not! I was working with an idealised simplification of the atmosphere, so this isn't of use for practical forecasting. Instead this is useful in shaping our understanding of the dynamics, which informs how numerical models used for prediction are designed. For example, improving the resolution in the stratosphere, or raising the lid of the model.

I've done my viva voce in October last year and expected graduated in the same year. However, the verdict was split and rose a debate among the committee. I was very confident with my research, however, one of my external wanted to fail me because he disagree with my findings. Another external examiner (a Professor) past me without any correction. Meanwhile my Internal examiner decided to give me minor correction. So, I got a major correction. Now, I m working on the correction. Wis me luck. Proud of you!!!

    Aren't they the same thing? What goes up (through the horizontal surface inside the cylinder) equals what goes down with a negative sign.

    This is awesome work! Now that you have simplified the oscillation correlation it will be more palatable to look at the electro magnetic effect of high sun spot activity on the ionosphere. Perhaps your work will create a more open perspective on the effect the ionosphere has on tropospheric temperature. Then the world will see space weather effects earth weather and we can get busy preparing for that solar slowdown which allows the polar winds to wriggle south. Sorry. Got exited about your work and started adding variables outside our atmosphere to figure out what makes the oscillation cycle. I’m just a farmer mechanic so I may have overstepped. It’s just those damn solar flares pushing on our poles have captured my attention lately and then I saw your video. Nice work young man.

    First time viewer, love this video and how everything is explained. I can't wait for better supercomputers to come online (especially state side - it's about time) and to see how researchers like Simon will better improve modeling. I get that meteorology is incredibly complicated and the chaos of earth's weather is immeasurably difficult to predict so I don't complain when weather 5 or 10 days out is wrong, but here in LA the meteorologists can't seem to predict the weather that's happening literally right now. It will be heavily raining and every app will say clear skies, zero percent change of rain. It takes me all of 4 calories to turn my eyes out the window and get a better reading. Not saying it's up to you to fix this, but Simon, please fix this.

    I was watching the civ game you guys were playing a couple of days ago and you mentioned the emissions that might be set off by getting and refining nuclear fuel, possibly deterring some from it, yes you fail go mention the significant amount more that comes from making solar panels, making and refining steel for wind, the land usage and more. I think we should all take after the European states that run off of hydroelectric and nuclear rather than believing in things such as solar that arent efficient at all at making energy, take up land, and indirectly cause a lot of pollution (not just co2, but ground pollution too when they break.), and wind that only work in places that have the terrain for it.

    Hi Simon. I’m assuming that the expanding height of the Troposphere over the decade’s doesn’t affect the relationship given the relative scales involved in the zones. It would merely alter the altitude of the transition which fluctuates in any event around the planet. Is that assumption correct? Does the trend in that expansion matter?

    That’s very cool to see, hope you get your PhD! Also, do you think the south of England will get snow when the storm over the Atlantic hits?

    As someone who was pretty good at physics in high school but never had calculus at uni, I'm kinda stunned/ashamed at how little this all made sense to me XD

    Not totally related, but where did you snag that god emperor poster?

    A Ph.D is nice, but if you want to go for the Nobel Prize you need to show how fluctuations in the magnetosphere alter interaction between the troposphere and stratosphere. Can you derive math that explains how convection from equatorial latitudes influences pressure gradients above the Arctic circle? Measurements suggest recent significant shifts in Earth’s magnetism at the equator are changing the behavior of the Hadley Cells. In turn, turbulence associated with cycling warm-to-cold air from the equator to the poles can influence the interaction covered in your thesis. Now, this is where the physics and math get interesting! Magnetic fields can affect airflow to limited extents in experiments. This is limited compared with the enormity of Earth’s magnesium. Model the influence measured in your lab and scale it up. Test your model against data for El Niño and La Niña events…. among other weather-influencing events. Let us know how you make out.
