Other special clouds - 25.10.2022 at 12.50 - 25.10.2022 at 13.15 Kauhava Observation number 110429

Visibility Unclassified

Jari Kankaanpää, Lakeuden Ursa

During the solar eclipse, interesting cloud formations flew in the south-west direction. This picture is a combination of two separate exposures mainly to document the atmosphere. I first shot a wide view of the cloud horizon with building silhouettes and zoomed into the sun with a focal length of 200mm and took the second picture through the astrosolar filter (mylar film). away from the sky around the sun and adjusted the blue-gray shade of astrosolar a little more reddish. The sun and moon are a little too big compared to the background of the picture, but at the right time and in the right place :)

    • Stacked lenticularis info

      Stacked lenticularis clouds, is a phenomenon in which there are several lentil-like clouds piled on top of each other. In the sky watch, the practical boundary between the conventional altocumulus lenticularis and the rarer lenticularis stack is considered to be at least three overlapping lenticular, i.e. layer-like, clouds.

      Lenticularis clouds are streamlined, flat cloud shapes. Typically, they occur when a mountain or mountain causes a vertical disturbance to the air flow. At the top of the resulting air wave, moisture may condense into cloud droplets, allowing a smooth lenticular layer to be observed. Sometimes such clouds also form without strong terrain in connection with various weather phenomena.

      Lenticularis clouds themselves are not uncommon and they can be seen quite often. Overlapping lentil cloud layers are clearly a less frequently seen phenomenon. Such a layerish pile cloud is formed when the wetter and drier layers of air alternate in the air. At that time, moisture condenses in some layers and not in others, so that even a very large number of lenticular layers can be detected.

      Only such clearly formed, layered lenticular clouds are collected in the sky due to their rarity.

      In Iceland, a layered lenticular cloud formed in a wave caused by mountains. Image from Wikipedia.

Hienosti olet saanut tunnelman taltioitua! Ihan mukavaa lenticularista pimennyksen aikaan.

Erikoispilvien bongailu lähestyy jo muutenkin. Polaaripyörre on muodostunut ja pakkasta on Suomen yllä jo lupaavat 73 astetta. Viime talvi oli helmiäisten osalta mainio. Toivottavasti sitä herkkua on tarjolla tänäkin talvena :)
