Anticyclone - Wikipedia
Anticyclones aloft can form within warm-core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large-scale sinking such as a subtropical ridge.
Anticyclonic tornado - Wikipedia
An anticyclonic tornado is a tornado which rotates in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere. [1] The term is a naming convention denoting the anomaly from normal rotation which is cyclonic in upwards of 98 percent of tornadoes.
Cyclones And Anticyclones: What Is The Difference? - Own Your …
2024年3月29日 · We take a closer look at cyclones and anticyclones and the differences between them. A cyclone is an air mass circulating a low-pressure system, which rotates counterclockwise in the Northern and clockwise in the Southern Hemisphere.
Anticyclonic storm - Wikipedia
An anticyclonic storm is a storm with a high-pressure center, in which winds flow in the direction opposite to that of the flow above a region of low pressure. [2] Unlike a cyclonic storm , anticyclonic storms are typically associated with fair weather and stable atmospheric conditions.
反气旋 - 百度百科
反气旋，是指中心气压比四周气压高的水平空气涡旋，也是 气压系统 中的高压。 北半球反气旋中，低层的水平气流呈 顺时针方向 向外 辐散，南半球反气旋则呈逆时针方向向外辐散。 反气旋的水平尺度比气旋更大，如冬季的蒙古— 西伯利亚高压 占据亚欧大陆面积1/4。 各个反气旋 中心气压 值一般为1020～1060hPa左右，最高气压纪录达1101.6hPa。 反气旋中风速较小，地面 最大风速 也只有20～30m/s，中心区风力微弱。 在反气旋控制下，大多天气晴朗。 反 气旋 的 中心气 …

2025年1月3日 · Common to both cyclones and anticyclones are the characteristic circulation patterns. The geostrophic-wind and gradient-wind models dictate that, in the Northern Hemisphere, flow around a cyclone—cyclonic circulation—is counterclockwise, and flow around an anticyclone—anticyclonic circulation—is clockwise.
Climate - Anticyclones, Pressure, Airflow | Britannica
2025年1月3日 · While cyclones are typically regions of inclement weather, anticyclones are usually meteorologically quiet regions. Generally larger than cyclones, anticyclones exhibit persistent downward motions and yield dry stable air that …
Anticyclone | meteorology | Britannica
anticyclone, any large wind system that rotates about a centre of high atmospheric pressure clockwise in the Northern Hemisphere and counterclockwise in the Southern. Its flow is the reverse of that of a cyclone (q.v.). This article was most recently revised and updated by …
What Is an Anticyclone? (with pictures) - AllTheScience
2024年5月21日 · An anticyclone is a region of high atmospheric pressure, with winds flowing outwards from the center. Due to the Earth’s rotation, the Coriolis effect deflects the winds, causing them to rotate clockwise in the northern hemisphere and counterclockwise in …
anticyclonic - 百度百科
anticyclonic，英语单词，主要用作形容词，作形容词时译为“ [气象] 反气旋的”。 [1] Earth's atmosphere has nothing that resembles a big, stable, anticyclonic flow. 地球的大气层没有哪一部分象是一股稳定的大反气旋流。 The area extension of the anticyclonic wind stress curl is beneficial to the formation and development of the anticyclonic circulation to the …
