English: Shown is a bed of Bermuda grass, Cynodon dactylon. The color of the grass turns from green to brown as it transitions to dormancy in fall. Frost damage by convecting air produced a particular pattern of green/brown regions referred to as "tiger striping". The spatial scale of the pattern is ≈20cm or 10in.

Notice the pronounced boundary effects, such as brown regions aligned to the edge of the lawn. This is suggestive of the underlying pattern-forming process. For the underlying process, see e.g. Ackerson, B.J., Beier, R.A. & Martin, D.L. Ground level air convection produces frost damage patterns in turfgrass.

The picture was taken with a Fairphone 4, ISO 112, f/1.8 and 1/336s exposure. It was cropped from the original with GIMP to anonymize the location. Taken in Leeland, North Carolina, USA on November 21 2023.

A close up of the same turf is shown in the picture on the right. The scale bar is 15cm / 6in.
