Indicator: A-05 Temperature extremes - percentage area of extreme annual mean temperatures
Data
Percentage area hot (above 90th percentile) and cold (below 10th percentile)
Source: Bureau of Meteorology 2005, Percentage area of Australia with annual mean T in Decile 1 (<10th percentile) and Decile 10 (>90th percentile).
What the data mean
The percentage of Australia experiencing cooler conditions shows a slight decrease over the reporting period 1900 to 2004, while the percentage experiencing warmer condition shows an increase, particularly since 1980.
Data Limitations
Nill known
Issues for which this is an indicator and why
Atmosphere - Climate variability and change - Weather
Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on our human, economic and environmental health.
Other indicators for this issue:
- A-01 Annual variation in the Southern Oscillation Index
- A-02 Rainfall trends - annual mean rainfall
- A-03 Rainfall extremes - inter-annual variations in annual extreme rainfall
- A-04 Temperature trends - annual mean temperature anomalies
- A-06 Extreme weather-related effects - cost of weather-related disasters
- A-36 Rainfall extremes - percentage area experiencing extreme wet and dry conditions
- A-37 Temperature trends - spatial trend in mean annual temperatures
- A-47 Rainfall deficiencies - drought
Land - Contributions and pressures between the land and the atmosphere - Climate
Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on the land.
Other indicators for this issue:
- LD-05 Terrestrial carbon loss rate and rate of land carbon sequestration
- LD-24 Severe drought and wildfire correlation
