Modelling of daily maximum temperatures over Australia from 1970 to 2012.

Wanishsakpong, Wandee; McNeil, Nittaya

ABSTRACT The variations of daily maximum temperatures over consecutive 5 day periods from 1970 to 2012 in Australia are described. The data were obtained from the Australia Bureau of Meteorology, comprising measurements from 85 weather stations. Linear regression was used initially to model the seasonally adjusted daily maximum temperatures. Factor analysis was used to classify the temperatures from the 85 stations into seven factors which correspond to seven geographical regions. The average maximum annual temperature in these seven regions ranged from 23 to 36 °C. A 6th order polynomial regression model was then fitted to investigate the trend and pattern of the temperatures in these seven regions. Similar increasing temperature trends occurred in the central, eastern, southern and southeastern parts of the country.
