What is meant by “the sun drawing water”?

Sometimes beams of sunlight appear-as streaks running from the sun toward the horizon. This is commonly called the sun drawing water, from the popular belief that it is due to the sun’s drawing up vapor by attraction from bodies of water on the earth. Many people regard the phenomenon as a sign of rain. It is produced when the sun shines through rifts in the clouds. The paths of the beams are made visible through the illumination of dust and other particles in the atmosphere. A similar phenomenon is produced on a small scale when a beam of sunlight shines into a room in which the air is dusty. The beams are in reality parallel. Their seeming convergence is a perspective effect similar to the apparent convergence of the rails of a long straight railroad track.
