This recent study by Acacia Pepler & co. describes a tale of more high pressure systems occurring over south eastern Aus in recent decades. From a snow perspective, these stupid highs keep the snow bearing weather systems well to the south. Explains some of the long term declines in snow depths, sadly. From a climate change perspective, I'd always accepted the physics of CO2 being an insulative gas, and in some sort of conceptual column, could accept a higher CO2 concentration would lead to greater heat retention. But as I'd always considered "the weather" to be a more function of winds, pressure patterns and airmass movement etc, I'd always had a mental gap between the increased insulative properties of a gas within an abstract column and real on the ground weather. However, this study would seem to fill that gap. Greater atmospheric heat retention due to increased CO2 concentration would seem to be enhancing the Hadley Cell, with a stronger downdraft along the sub-tropical ridge (ie stronger anti-cyclones over Aus), manifesting in less of what we all like here, snow. https://link.springer.com/epdf/10.1007/s00382-019-04819-9?author_access_token=45rF8WRELZ-MojG2XaT-iPe4RwlQNchNByi7wbcMAY4iiywiUo50pnNJDU-g6P2Mi2xXGmZNjsl-ocavKI5dP1iy2uhSf6CsYFWv8Nm16tKSh4Wqk9MuY_xgSV62BeKS6vinYLKar7t-0K5hZQKKWQ== Read this article in conjunction with another great graphic I found recently on the internet. Unfortunately a bit depressing, I feel bad for my kids who've just caught the snow bug.
