网页2024年9月13日 · Climate - Anticyclones, Pressure, Airflow: 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 may extend horizontally many hundreds of kilometres.

网页2024年9月13日 · Cyclones and anticyclones are regions of relatively low and high pressure, respectively. They occur over most of Earth’s surface in a variety of sizes ranging from the very large semipermanent examples described above to smaller, highly mobile systems. The latter are the focus of discussion in this section.
