The late afternoon sun bathed the right bank in a mellow light, while in the west, dark clouds sped toward the city, white streaks flickering in their centers.

There was a little sigh from the tunnel's mouth and a silvery misty cloud sped from it, over the pilots and straight through the opened door.

What looked like a cloud of smoke still drifted outside the cookhouse... until, as I watched, the cloud whirled away from the building and sped in our direction.

They landed near the equator, where Tau was an amorphous white glare overhead, where abrasive clouds sped along the ground on hurricane winds almost hot enough to boil water.

Tattered clouds sped by, high overhead.

They moved slowly, while clouds sped by; dark, then light again.

Deep purple clouds with silver edges sped across the sky, and warm breezes flowed across the choppy, charcoal bay, rustling sea grass, and sharp black pine needles.

Above our head clouds sped across a deep blue sky, throwing shadows like swooping birds across the graceful Temple of Artemis.

Broken clouds sped overhead, and short splashes of sun washed the chalet, then scuttled up the steep mountainside beyond.

But by the time we got there a gray misty cloud was speeding across the sky.
