Cloud Streets are also known as Horizontal Convective Rolls. They are an easily recognisable cloud feature. I compiled a time lapse movie of cloud streets. I decided to use a short interval between each frame. The clouds were evolving rapidly. It was a very windy day. I used an interval of I think 1 second. Its played back at 24 fps. This means I would get 16.625 seconds of video (at 24 fps).
I can’t remember exactly how long it too but I think it was around half an hour to get the photos. You do need a lot of patience with time lapse. You also need lots of movement. What I liked about the scene I shot was the rapidly changing light and cloud motion.
Cloud streets tend to form roughly parallel to the wind direction. What I noticed in this time lapse was that the clouds were slowly spreading laterally to fill the gaps between them.
In very rare circumstances cloud streets can have a paisley leaf like pattern. These are distinctive in satellite images and are called Von Karman Vortex Streets. In the future I would like to do more weather time lapses. There are so many different types of clouds to photograph. You never know how a time lapse will turn out and that is part of the fun of it. I’m learning a lot about cloud evolution from doing this sort of photography.
I prefer time lapses that have a smooth transition between each frame. I don’t like time lapses which have a blocky appearance. However everyone likes different things. I do hope you enjoy this cloud streets time lapse. Let me know what you think.
I used a Sony A7s and took the frames in RAW+JPEG. I did have to use JPEGS in the final video otherwise the file size would have been massive!
