A new study appearing in the Journal of Weather and Climate Extremes titled “Historical extreme rainfall events in southeastern Australia” – led by LindenAshcroft, School of Earth Sciences, University of Melbourne – shows that even more extreme weather in terms of rainfall existed before 1900 in Melbourne, Sydney and Adelaide.

Moreover, the authors found a “moderate and relatively stable relationship between El Niño–Southern Oscillation (ENSO) and annual variations of total rainfall and the number of raindays.”

A funny thing happens when you line up satellite and surface temperatures over Australia. A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models (…)

The England & Wales Precipitation Series has now been updated for last year.
Precipitation totalled 952mm during the year, slightly above the series average of 918mm. In ascending order, 2017 ranked 158th.
There seems to be little evidence of any real trends. Whatever trend can be winkled out of the numbers will likely be too small to notice, and swamped by the natural variability in the data.
The wettest years remain 1872 and 1768. The driest were 1788 and 1921.
