Explanation:

Although you have not shown the poem you are referring to, from the context of your question we can see that you are referring to the poem "Ode to the West Wind" where in lines 15 and 16, poet Mary Shelley compares the wind moving the clouds with the wind that move the dead leaves that have fallen from the trees, so that new leaves can re-emerge. In this comparison, Shelley claims that the wind shakes the clouds as if they were branches of trees and drags them across the sky as if they were leaves, dropped on the ground.
