Heatwave conditions in 2017 delivered record-breaking temperatures to Sydney and the surrounding regions. The following visualisation is narrated by Dr. Annette L. Hirsch of the ARC Centre of Excellence for Climate Extremes (UNSW), and analyses the role of surface conditions during heatwave events, with a specific emphasis on complex urban areas. Urban areas are often hotter than their rural surroundings, a phenomena is known as the urban heat island effect, and can be influenced by coastal breezes, inland airflow and extreme temperatures. A new configuration of the weather and research forecasting model is able to visualise urban weather conditions at very high resolutions.
