Recent Climatic Trends and Analysis of Monthly Heating and Cooling Degree Hours in Sydney

Recent climatic trends of two nearby stations in Sydney were examined terms hourly ambient air temperature and wind direction for the time period 1999–2019. A reference was set monthly number cooling (CDH) heating (HDH) degree hours that temperatures exceeded 24 °C (T24) or below 14 (T14), parameters affecting not only energy demands but also quality life. The linked to dominant synoptic conditions local phenomena: sea breeze inland winds. results indicated both areas had higher mean HDH (980–1421) than CDH (397–748), thus demands. showed a T14 (34–471) T24 (40–320). complete spatiotemporal profile variations given through analysis their dynamic progress correlation. In order estimate daily values HDH, empirical models calculated per month based on maximum minimum temperatures. use forecasted weather created may later be used planning scenarios.
