Snyder and the global temperature graph

Global average temperatures -- adding Snyder (2016)

A paper in this week’s Nature by Caroline Snyder at Stanford provides a fresh attempt at estimating global average surface temperatures across the Pleistocene (her estimates cover the last 2 million years).

Th' th' th' th' th' that's all folks

BOM 4-day (err, ECMWF) for this week.

Update (26 September):

This one’s looking quite interesting now on the Bureau of Meteorology’s 4-day chart, which of course is drawn off the excellent European ECMWF model (for historical reasons…).

12-13 July

...And for Tuesday

Models agree there’ll be quite a bit of rain Sunday-Monday from the tropical feed ahead of the low, then a nice cold winter blast Tuesday-Wednesday. We should see another net gain in snow depth at Thursday’s measure.

Pretty much as per the update. It looks like there might have been nearly 20 cm at Perisher Valley on Tuesday, then 25 mm of rain Wednesday-Thursday. Victoria looks similar or a little wetter.

Season starter ... at last

Spencers Creek season start

Update (22 June): Tuesday night came through (with good accumulations down to below 1600 m, not 1800 m), so we’re looking forward to seeing a number from you tomorrow, Hydro guys.

23-25 June


Outcome (27 June):

There was about 90 cm of snowfall in aggregate for this event on my best estimate, a bit under half of which came with the lead-up system starting Tuesday night … which I barely rated initially. Ho hum; wrong again.

It’s interesting to look at where the 500 hPa spaghetti plot finished up, for future future calibration. The blue line did not reach the alps:
