"Cirrus" in latin means curl and these clouds are named because they resemble wisps of curly hair. Cirrus clouds are located high above the Earth, as many as six miles high in the sky. Cirrus clouds form when a front of warm dry air meets a body of cool dry air. These clouds form in winter and in summer and the weather they cause depends on the speed and strength of the weather fronts, although they are often a sign that it is going to rain.
