v. t. e. In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones). Most high- and low-pressure areas seen on weather maps (such as surface ...
A synoptic chart drawn at the West Terrace Observatory, Adelaide that is larger in geographical reach than any known chart from another meteorological service for that time period. The Todd Weather Folios are a collection of continental Australian synoptic charts that were published from 1879 to 1909. The charts were created by Sir Charles Todd ...
Weather map. A surface weather analysis for the United States on October 21, 2006. A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings.

When the deep lows are significant, they can affect the south as well. [1] The Australian monsoon (AUM), also known as the Australian summer monsoon (ASM), [2] and the Australian-Indonesian monsoon (AIM), [3] is a monsoon system that increases thunderstorms and rainfall over many areas of Indonesia and northern Australia, from the far northern ...
An east coast low on 27 July 2020 taken by Himawari 8. Australian east coast lows (known locally as east coast lows, maritime lows, and east coast cyclones [1]) are extratropical cyclones or low-pressure systems on the coast of southeastern Australia that may be caused by both mid-latitude and tropical influences over a variety of levels in the atmosphere.
Prognostic chart. A prognostic chart is a map displaying the likely weather forecast for a future time. Such charts generated by atmospheric models as output from numerical weather prediction and contain a variety of information such as temperature, wind, precipitation and weather fronts. They can also indicate derived atmospheric fields such ...
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather ...
Fremantle Doctor. The Fremantle Doctor, the Freo Doctor, or simply The Doctor, is the Western Australian vernacular term for the cooling afternoon sea breeze that occurs during summer months in south west coastal areas of Western Australia. The sea breeze occurs because of the major temperature difference between the land and sea.
