Altocumulus and altostratus clouds usually bring cold, windy conditions. If you come across this type of weather make shure you are protected from drizzle or light snow.
Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is

, where P is the power through an area A. The SI unit for I is W/m2. The intensity of a sound wave is related to its amplitude squared by the following relationship:
