Altijd leuk die metingen in niemandsland. Western Australia heeft een oppervlakte van half europa.
Dat meetstation ligt in de middle of nowhere vlaktes en nog is vlaktes. Leuk voor de buhne.
Hier in Perth heb ik er iedergeval niks van gemerkt. Gewone temps voor de tijd van het jaar, zo rond de 28-30 graden.
While the temperature topped out at 29.4C at 1pm for Perth locals enjoying a lazy Sunday, a record was about to be set in WA’s Pilbara.
Roebourne Airport reached 48.1C just after 2pm. The autumn scorcher was a new high for March.
According to the Bureau of Meteorology, it beat the previous high of 46.6C set at the airport in March, 2005 and the 47.8C recorded at the former town weather site 21 years ago.
Thankfully there has been some respite with the temperature in the town dropping to 43.8C at 5pm.

En dan dit:
The Australian Bureau of Meteorology, BOM, doesn’t have a set of temperature thermometers regularly positioned across the landmass of Australia from which it might derive an average annual temperature. Rather many more of it’s approximately 750 temperature recording stations are in south eastern Australia, some have records that date back to the 1850s, while others only started recording last year.
How do you derive an average annual temperature for Australia from such a mix of measurements?
The Bureau’s solution is to select a subset of about 112 stations from the 750. Some of the stations in the subset started recording temperatures in the 1850s, others not until the 1960s. Then the bureau truncates the longer temperature records, in some cases by discarding over 50 years of data, indeed everything before the somewhat arbitrary date of 1910. Data before this date is not considered reliable, but then the Bureau applies corrections to some of the rest of the data even though it should be reliable. Then the adjusted and truncated values from the subset are fitted to a grid to generate an area-weighted average of the data.
