On 27 November 2014, Brisbane was hit by a Mesoscale convective system [58] which brought wind gusts up to 141 kilometres per hour (88 mph), reaching speeds of Category 2 tropical cyclones, and hail stones up to 8 centimetres (3.1 in) in diameter. It was the worst storm to hit Brisbane since 18 January 1985 [59] and caused over A$ 1 billion in ...
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

Brisbane's wettest day occurred on 21 January 1887, when 465 millimetres (18.3 in) of rain fell on the city, the highest maximum daily rainfall of Australia's capital cities. The wettest month on record was February 1893, when 1,025.9 millimetres (40.39 in) of rain fell, although in the last 30 years the record monthly rainfall has been a much ...
This is the equivalent sea-level pressure; Tosontsengel is located at 1,300 metres (4,300 ft) above sea level. The highest adjusted-to-sea-level barometric pressure ever recorded (below 750 meters) was at Agata, Evenkiyskiy , Russia ( 66°53′N 93°28′E / 66.883°N 93.467°E / 66.883; 93.467 , elevation: 261 m (856.3 ft)) on 31 ...
Pressure as a function of the height above the sea level. There are two equations for computing pressure as a function of height. The first equation is applicable to the atmospheric layers in which the temperature is assumed to vary with altitude at a non null lapse rate of : = [,, ()] ′, The second equation is applicable to the atmospheric layers in which the temperature is assumed not to ...
The 2023–24 Australian region cyclone season was the fifth consecutive season to have below-average activity in terms of named storms. Despite this, it was the second in a row to have at least five severe tropical cyclones, including Australia's wettest tropical cyclone on record.
Upon crossing this border, Daryl was assigned a second name, Agnielle, by Mauritius. Over the following days, the system further deepened, peaking in strength as a Category 3 on the Australian intensity scale with 205 km/h (125 mph) and a barometric pressure of 915 hPa (mbar; 27.02 inHg). Steady weakening took place due to markedly stronger ...
The Australian High, also known as the Australian subtropical ridge, [1] is a large, semi-permanent high pressure area or subtropical anticyclone that seasonally vacillates between the Great Australian Bight in the south to the Northern Territory in the north. [2] It is generally located between 25 and 40 degrees of south latitude, depending on ...
