I pass before the sun, yet make no shadow. What am I?

Why this works

This riddle plays on the idea of visibility and physical presence. The "wind" is something that can be felt and heard, and it moves through the air, often causing leaves to rustle or clouds to shift, but it is invisible itself, thus it "makes no shadow." The clever twist is that while it can interact with the environment around it, it lacks a tangible form that would cast a shadow, making the answer both logical and poetic.
