Black Nor'easter
A black nor'easter is a persistent and potentially violent north-easterly storm that occurs on the east coast of Australia, particularly from southeastern Queensland to southern New South Wales, usually between late spring and early autumn, about two days a year (or more, depending on the intensity).Black nor'easter to soak Sydney and surrounds by Ben Domensino from Weatherzone. 4 April 2024. Retrieved 5 April 2024. Developing offshore as a deep coastal trough, the storm is heralded by the rapid build-up of dense black cloud that brings heavy rainfall and strong northeasterly winds along the east coast of Australia. A black nor'easter can be a combination of surface Trough (meteorology), troughs, onshore flow, and a low pressure system, low. ...

Storm Clouds Over Sydney 3 - Panoramio
A storm is any disturbed state of the natural environment or the atmosphere of an Astronomy, astronomical body. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy Precipitation (meteorology), precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), wind transporting some Chemical substance, substance through the Earth's atmosphere, atmosphere such as in a dust storm, among other forms of severe weather. Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical and horizontal wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobil ...

Sea Temperature
Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of ''surface'' varies in the literature and in practice. It is usually between and below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. Warm sea surface temperatures can develop and strengthen cyclones over the ocean. Tropical cyclones can also cause a cool wake. This is due to turbulent mixing of the upper of the ocean. Sea surface temperature changes during the day. This is like the air above it, but to a lesser degree. There is less variation in sea surface temperature on breezy days than on calm days. Coastal sea surface temperatures can cause offshore winds to generate upwelling, which can significantly cool or warm nearby landmasses, but ...

Atmospheric River
An atmospheric river (AR) is a narrow corridor or filament of concentrated moisture in the atmosphere. Other names for this phenomenon are tropical plume, tropical connection, moisture plume, water vapor surge, and cloud band. Atmospheric rivers consist of narrow bands of enhanced water vapor transport, typically along the boundaries between large areas of divergent surface air flow, including some Weather front, frontal zones in association with extratropical cyclones that form over the oceans. Pineapple Express storms are the most commonly represented and recognized type of atmospheric rivers; the name is due to the warm water vapor plumes originating over the Hawaiian tropics that follow various paths towards western North America, arriving at latitudes from California and the Pacific Northwest to British Columbia and even southeast Alaska. Description The term was originally coined by researchers Reginald Newell and Yong Zhu of the Massachusetts Institute of Technology in ...

Cut-off Low
A cut-off low (or cutoff low), sometimes referred to as the weatherman's woe, is defined by the National Weather Service as "a closed upper-level low pressure system, low which has become completely displaced (cut off) from basic Westerlies, westerly current, and moves independently of that current." Cut-off lows form in mid-latitudes (usually between 20° and 45°) and can remain nearly Block (meteorology), stationary for days. Formation A cut-off low is a cold-core low where wind in the upper levels of the troposphere is "cut off" from the primary westerly winds of the jet stream. They are formed when a Trough (meteorology), trough in the upper-air flow pinches off and separates into a closed circulation. It is defined by concentric Contour line, isotherms around the Eye (cyclone), core of the low. Because they are a feature of the mid- to upper-troposphere, they may not be visible on a surface weather analysis. Because they are separated from the main westerly flow, cut-off lows ...

2022 Eastern Australia Floods
The 2022 eastern Australia floods were one of the nation's worst recorded flood disasters with a series of floods that occurred from late February to early May in South East Queensland, the Wide Bay–Burnett and parts of coastal New South Wales. Brisbane suffered major flooding, along with the cities of Maryborough, Gympie, the Sunshine Coast, Caboolture, Toowoomba, Gatton, Ipswich, Logan City, the Gold Coast, Murwillumbah, Mullumbimby, Grafton, Byron Bay, Ballina, Lismore, the Central Coast and parts of Sydney. Twenty-four people are known to have died during the disaster. Throughout South East Queensland and the Wide Bay–Burnett, almost one thousand schools were closed in response to the flooding, evacuations took place and the public were advised to avoid non-essential travel. Food shortages were reported across the region, due to the ensuing supply chain crisis as well as affecting communities in outback Queensland. The flooding caused the ground across South W ...

The New Daily
''The New Daily'' is an online Australian newspaper founded in 2013, and owned by Industry Super Holdings, which represents industry superannuation funds. History ''The New Daily'' was started by AustralianSuper, Cbus and Industry Super Holdings in 2013. The venture was deemed controversial due to its ownership by non-profit superannuation funds (which are legally obliged to spend money in their members' best interests) regarding both the publication's commercial nature and its editorial independence. The founding editor was Bruce Guthrie. In 2016, it became wholly owned by Industry Super Holdings. The initial funding and investment of the entity was paid for using funds from those organisations, with justifications made by super-fund management that investing in the news site would be a worthwhile activity for super-fund members for a number of reasons. When the publication was launched, its owner AustralianSuper planned to force subscriptions from its members unless t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hail
Hail is a form of solid Precipitation (meteorology), precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of ice, water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and Transparency and translucency, translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible during most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thunderstorms
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in cumulonimbus clouds. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms can produce little or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course ...
