Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes. Maps using isotherms show temperature gradients, [2] which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located.
5 January 1863 is Sydney's first recorded 40 °C (104 °F) day, when the mercury hit 41.6 °C (106.9 °F) at Sydney's Observatory Hill. [11]During January 1896, a state wide heatwave blasted through NSW and caused the mercury in Sydney to hit 40.7 °C (105.3 °F) on the 6th and 42.5 °C (108.5 °F) on the 13th, this ended Sydney's longest streak of days under 40.0 °C (104.0 °F) which lasted ...
The JORN ionosonde network is made up of vertical ionosondes, providing a real time map of the ionosphere. Each vertical incidence sounder (VIS) is a standardized Single-Receiver Digisonde Portable Sounder, [25] built by University of Massachusetts Lowell for the JORN. A new ionospheric map is generated every 225 seconds. [19]

Climate map of Australia. By far the largest part of Australia is arid or semi-arid. A total of 18% of Australia's mainland consists of named deserts, [20] while additional areas are considered to have a desert climate based on low rainfall and high temperature. Only the south-east and south-west corners have a temperate climate and moderately ...
