Watching the sky

A five-minute pause is enough to notice movement.

Choose a place with a clear view and spend a moment looking in each direction. Near clouds can move at a different speed from a thin layer high above them. Their edges may grow, soften, or disappear while you watch.

Use a fixed object, such as a roof or a branch, to judge the movement. Write down the time, the direction of the wind at ground level, and how much of the sky is covered. These simple observations make it easier to compare one day with the next.

Clouds are part of a changing system, so a single view offers only a small piece of the picture. The value of keeping a notebook is in returning to the same place and learning what changes over time.
