  • The ITCZ is an interesting case to use here! You’re right that it’s the thermal equator and has low pressure, but you’ve gotta consider convection and wind direction too (i.e. the whole Hadley cell). Convection (caused by solar heating) causes low pressure too, and pressure is often relative.

    When you’re thinking about stuff on a global scale you’ve always gotta consider the global atmospheric circulation

    There’s a lot of good explanation in the link I sent - it’s tricky trying to consider all the variables together, but I would say that variations in density (latitudinally, at least - unless you want to start talking about hydrostatic balance!) doesn’t account for the variation in pressure or temperature.

    the wet bulb temperature1 is just the temperature of a wet thermometer, and varies with humidity and temperature. Wet bulb temp is never higher than the dry bulb temp, so (entertainingly) you’re proposing that the meaning of 100° varies wildly and is always lower than the true temperature, effectively making the air temperature always ≥100°, and increases when the air is drier, like some sort of inverse relative humidity.

    1(I’m aware you probably didn’t mean wet bulb temperature here, but let’s have fun with the idea) :)

    AuDHD and completely caffeine free (and stimulant/meds/drugs free too). Caffeine definitely doesn’t work for me like it does for other people - makes me sleepy and headachey. I’d rather just work with what I’ve got, (noise cancelling headphones + being inflexible) even if it has limitations


  • The weather risk management of festivals in the UK is often very unsafe and met with attitudes of “the show must go on!” and “just deal with it!” without any proper planning or attention to forecasts.

    Most of Renee Rapp’s team’s equipment was completely drenched in water and presumably ruined. Whilst it’s fine for the festivalgoers to make their own decisions, when it’s thousands of pounds worth of electrical equipment - the event organisers really should know better.




  • Where I live, in December, it’s already night by 4pm, whereas in July, 4pm isn’t even the peak of heat yet. But if someone said “good evening” to me at 4pm in either of them, I’d prob accept it either way, and I’m a meteorologist

    Also: In the UK and the US, the typical meteorological standard is just to split seasons by month (DJF MAM JJA SON) for easy stats reasons, but other countries have entirely different standards based on climate. Different people have different definitions and it’s completely fine
