EXAMPLE 10/15

While they are most common in the summer, arcus clouds can occur virtually any time of the year. Here is a striated shelf cloud over the Gulf of Trieste, NE Italy on March 31 – early spring.

And a shelf cloud over W Slovenia in winter, on February 29.

Shelf clouds can also appear deep in the winter: here is one over the Gulf of Trieste, NE Italy on January 11.
