Stationary and non-stationary temperature-duration-frequency curves for Australia

Abstract Australian summer heat events have become more frequent and severe in recent times. Temperature-duration-frequency (TDF) curves connect the severity of episodes various durations to their frequencies thus can be an effective tool for analysing extremes. This study examines using data from 82 meteorological stations. TDF been developed under stationary non-stationary conditions. Generalised Extreme Value (GEV) distribution is considered estimate extreme temperatures return periods 2, 5, 10, 25, 50 100 years. Three major climate drivers Australia as potential covariates along with Time develop curves. According Akaike information criterion, framework modelling provides a better fit than its equivalent. The findings beneficial offering new aid adaptation mitigation at regional level Australia.
