Tuulivirta

Tuulivirta is a phenomenon observed in atmospheric science, where winds create a visible pattern of waves or ripples in the cloud formations. This effect is most commonly seen in cirrus clouds, which are high-altitude clouds composed of ice crystals. The waves are formed due to the interaction between the wind and the stability of the atmosphere. When a strong wind blows over a stable layer of air, it can cause the air to rise and fall in a regular pattern, creating the characteristic wave-like structures in the clouds. These waves can be seen from the ground as long, parallel bands of clouds that appear to be moving in a direction perpendicular to the wind. Tuulivirta is a fascinating example of how atmospheric dynamics can create visually striking patterns in the sky.
