  • I’m nearly certain it is true that Russia has dirt on him. But serious question: what possible dirt on trump could even slightly alter his base in the United States? I’m not convinced anything could. They could have videos of him raping an entire kindergarten class and his cult wouldn’t care. So at this point, what power does Putin actually hold? Trump (in theory) could tell Putin to fuck off and that would be the end of it.

    I think it’s admiration and not blackmail that keeps trump sucking Putin’s dick. I think Trump looks at Russia and wishes he could have the same unchecked power that Putin has and so he looks up to him.



  • My science falls more on the mesosphere/stratosphere side from space weather effects (top down rather than bottom up). However, SSW events are fascinating phenomena and have profound impacts on potentially all layers of the atmosphere. I’m currently developing (with lots of help) a high-top forecasting model that extends from the surface to the thermosphere. Forecasting SSW events are something we are hoping to improve with this model having a fully resolved mesosphere. I’ll edit my original post as I was hard on your article. I’ll also DM you my email and we can chat further.



  • I don’t disagree with its usefulness as a potential predictor once it is formed. I’ve seen the literature on its impact on NAO and the AO. This is particularly true following sudden stratospheric warming events and its correlation with cold air outbreaks in the NH. However claiming that it is “weak” is misleading since it hasn’t formed yet. And to my knowledge, the physical mechanism of the interaction between the stratospheric polar vortex and the tropospheric jet has not been determined. We think it is related to wave reflection from planetary wave and gravity waves during a sudden stratospheric warming event. But if we don’t understand the mechanism, forecast or climate models are incapable of predicting them since that physics will not be included in the models. At this point, using the jet stream in the stratosphere (the unformed vortex) as a predictor for the NH winter will not be better than climatology.



  • I work in the middle atmosphere and several things in this article I disagree with. First off, the polar vortex is a stratospheric and mesospheric jet stream that exists in the winter time. There is no polar vortex in the stratosphere during the summer. Let me repeat that. There is no polar vortex in the northern hemisphere right now! So how are you using it for predictions? Second, the media stole the term “polar vortex” for the Arctic jet stream that exists in the troposphere. Moreover, while correlations have been made (see Baldwin et al., 2021) on the stratospheric impact on the tropospheric weather, the physics aren’t well understood. Assuming you can make predictions on the northern hemisphere winter based on the polar vortex in the stratosphere (which again, doesn’t exist yet because it is summer) months out is unlikely.

    Edit: I edited out the argument that the OP may not reputable since they are a meteorologist in Canada.

    Edit2: I’ve edited my original post slightly after discussing this concept with the OP.
