Eastern Australia has gone from dry, stable westerlies in mid-October to something a little more showery for the start of November. Here's how the broad-scale pattern has evolved. Note that negative AAO/SAM (reds over Antarctica) hasn't quite dissipated yet.

Antarctic origins of the air mass arriving over south east Australia.

given one of the few good uses for LLMs is coding assistance maybe tech council members should immediately open source all their code under a permissive license. to do otherwise would risk harming investment in the AI industry in Australia, imo

Did I ever share this paragraph with you from one of my journal articles? ("Railways and Water in Australasia, 1870s to 1914", History Australia 17:3, 2020)

Drowned herds. Towns underwater. Farmers in NSW are facing ‘absolute devastation’

Flooding rain continues over north east NSW, with rain now also falling west of the Divide thanks to the arrival of a second upper-level low. This system will track south on Friday, clearing the rain by Saturday.

✨Editor's Pick✨ In Geophysical Research Letters, researchers show that critical flow theory can predict river discharge based on the spacing of standing waves captured by Google Earth images. 🔗 Learn more in @eos.org : buff.ly/TdaH31L #AGUPubs #STEM #EarthScience #Hydrology #RemoteSensing

Starting on bsky with a new preprint: "How to deal w___ missing input data" doi.org/10.31223/X50... Missing input data is a very common challenge in deep learning for hydrology: weather providers have outages, some data products start later than others, some only exist for certain regions, etc.
