"Article Evaluation"

Everything in the article relates to an anticyclonic storm, however, I think too much weather is presented that can distract the viewer from the focus of an anticyclonic storm. For example, there is a "part of series on weather" list that has multiple links to different weather events and other phenomena where it is hard to find where the anticyclonic storm is located within these tabs. Upon further examination, "anticyclonic storm" is not even listed in this. Only "anticyclone" is which seems to be a totally different page. The article has accurate scientific information, but it gets all of its information from one source. Different sources should be added and content should be presented as deemed appropriate and would thus improve the article as a whole. Multiple Wikipedia hyperlinks are provided throughout the article such as northern hemisphere, Coriolis effect, great red spot, etc.

The tone of the article represents a neutral approach. It is very independent and presents the facts appropriately and without bias.

For the sources, the page uses one main source, a book, entitled, The Weather Book, by Jack Williams. There is no link. For the picture provided within the article, a link is provided to the NASA website.

There is absolutely zero discussion on the article's talk page. This page has been subject to an assignment before and is apart of WikiProject Meteorology. The article has been rated Stub-Class on the project's quality scale and rated low importance on the project's importance scale.

Article Draft
An anticyclonic storm is a weather storm formed in an area of high pressure, where winds around the storm flow in the opposite direction compared to typical cyclonic storms above a region of low pressure. These storms can create powerful mesoanticylonic supercell storms that can create anticyclonic tornados.

Description
Anticyclonic storms usually form around high-pressure systems. These do not "contradict" the Coriolis effect; it predicts such anticyclonic flow about high-pressure regions. Anticyclonic storms, as high-pressure systems, usually accompany cold weather and are frequently a factor in large snowstorms. Along a cold weather front, an anticyclonic storm is called a wave, frontal, or mid-latitude anticyclonic storm when they are connected to a weather front. . In the Northern Hemisphere, anticyclonic storms involve clockwise wind flow; in the Southern Hemisphere, they involve counterclockwise wind flow.

Mesocyclone Super-Cells
Supercells are long-lasting convective storms that are formed when thunderstorms are accompanied by a strong vertical wind shear. A supercell will have a rotating updraft (mid-altitude mesocyclone) and a downdraft. The mid-altitude mesocyclone typically moves to the right, but when it moves to the left, mesoanticylonic super-cells are created. This is formed when the rotating updraft moves anticyclonically. Left moving supercells can be strong producers of hail storms, but rarely produce anticyclonic tornados.

Anticyclonic Tornados
Anticyclonic tornadoes can occur; while tornadoes' vortices are low-pressure regions, this occurs because tornadoes occur on a small enough scale such that the Coriolis effect is negligible. For an anticyclonic tornado to occur in an anticyclonic supercell, it must go through tornadogenesis in three steps. First, form a rotating updraft aloft. Second, develop a cyclone at the ground. Lastly, create the tornado. Under the right conditions, these can develop into a succession of anticyclonic tornadoes.

Examples

 * Hartmut, Scandinavia: From 25 February – 4 March 2018, a Siberian airmass triggered a rare instance of an "anticyclonic blizzard" during an exceptionally strong anticyclone with hurricane-force maximum gusts of 187 km/h (116 mph) and peak central pressure of 1056 hPa. It caused the Beast from the East, a deadly cold wave that channeled freezing air and large amounts of snow over Europe. The interaction of Anticyclone Hartmut and Cyclone Emma intensified the wind and snowfall threat in Western Europe, particularly the British Isles.
 * Neptune: In 1989, Voyager 2 discovered a anticyclonic cloud system (DS2) in convective storms at 55°S on Neptune. There were bright and high clouds associated with this system with an anticyclonic vortex. These cloud systems on Neptune are known as 'companion clouds' because they are formed similarly to the cloud structures on Earth that can lead to anticyclonic storms. Voyager 2 discovered convective storms where one of which resembled anticyclonic behavior. This convective storm was located in the DS2 anticyclone located at 55°S . There were bright and high clouds associated with this system with an anticyclonic vortex.
