  Cumulus mediocris radiatus

  The image shows typical detached Cumulus clouds. The upper, sunlit parts are bright white, while the bases are relatively dark and nearly horizontal. The clouds show modest vertical development with small protuberances and sproutings at their tops, indicating the species mediocris. Of particular interest, the clouds are arranged in bands or lines nearly parallel to the wind direction, commonly called cloud streets, which identify them as the variety radiatus. Due to perspective, when viewed along the lines, they appear to converge towards a point on the horizon. Two aircraft condensation trails, Cirrus homogenitus, are visible at the top of the image.

  Cumulus mediocris radiatus

  Cumulus mediocris cloud over northern France, viewed from an aircraft on descent towards London Gatwick Airport, England, UK. The view is looking north-north-east along the English Channel coast, which can be seen in the top left of the picture. The air flow at cloud height is from the north-west, from left to right across the image, and the clouds are aligned in lines or streets at 1, 2 and 3, making this the variety radiatus.
