11 Απρ 2024 · Have you ever gazed skyward and spotted a cloud that resembled a flying saucer or a giant contact lens? These captivating formations, known as lenticular clouds (or Altocumulus lenticularis for the science buffs), are a unique phenomenon often associated with mountainous regions.
Lenticular cloud over the Antarctic ice near Scott Base. Lenticular clouds (Latin: Lenticularis lentil-shaped, from lenticula lentil) are stationary clouds that form mostly in the troposphere, typically in parallel alignment to the wind direction.
29 Μαΐ 2024 · Lenticular clouds form primarily in the troposphere, typically aligning perpendicular to the wind direction. This occurs when moist air flows over elevated terrain, such as mountains or hills. The key process behind the formation of lenticular clouds involves orographic lift, where an airflow encounters topographic barriers.
31 Μαΐ 2017 · There are actually three types of lenticular clouds: altocumulus standing lenticularis (ACSL), stratocumulus standing lenticular (SCSL), and cirrocumulus standing lenticular (CCSL).
Lenticularis. (Section 2.2.2.2.8) Clouds having the shape of lenses or almonds, often very elongated and usually with well-defined outlines; they occasionally show irisations. Such clouds appear most often in cloud formations of orographic origin, but may also occur in regions without marked orography.
20 Απρ 2024 · Lenticular clouds remind us of the intricate and dynamic nature of our atmosphere. Their formation and presence offer insight into the complex interplay of air currents, moisture and topographical features.
In the video below, you can see the lenticular clouds changing shape, but remaining relatively in place, continually forming on the upwind side and dissipating and evaporating downwind, though their forms are relatively elongated and thin and are relatively broad.
