The weather can be a metaphor for emotions. It can be bright and sunny one day, gloomy the next.
I can imagine wind as a metaphor for thoughts, blowing through the mind, never-ceasing. We draw on the forces of nature to represent our inner experiences. Maybe our internal environment follows some of the same laws of physics; like fluid dynamics.
Anyway, this picture is of two people fishing at the pier on a foggy day. At least, that's what it appears to be on the surface. Beyond that, it could be something much closer to home.
