furosha

n. the eerie tranquility of fast-moving clouds, who pass through your patch of sky like a drifter stepping into your entryway to warm up for a minute, ruffling the ice from his beared before he nods his gratitude and turns back into the air.

Japanese ふ浪者 (furōsha), vagrant, vagabond. Onomatopoeic to the sound of a sudden gust of wind. Pronounced "fuh-roh-shuh."
