They are known as Asperitas Clouds—a new class of clouds just added to the International Cloud Atlas last month (previously known as Undulatus Asperetas clouds). Are you Cirrus? –yes…yes, I am. The undulating effect of the cloud base usually the result of unstable air flowing into a region of stable air (like we saw this morning).
