A sunbreak is a natural phenomenon in which sunlight obscured over a relatively large area penetrates the obscuring material in a localized space. The typical example is of sunlight shining through a hole in cloud cover. A sunbreak piercing clouds normally produces a visible shaft of light reflected by atmospheric dust, called a sunbeam. Another form of sunbreak occurs when sunlight passes into an area otherwise shadowed by surrounding large buildings through a gap temporarily aligned with the position of the sun.
