Due to the daily rotation of the Earth the lower layers of earth's atmosphere are continuously crossed by horizontal lines of the geomagnetic field. For this reason, near the earth's surface there is an upward-directed Lorentz force. Under the action of this force the positively charged objects move upward and the negative charges down. The existence of this force makes it possible to explain some poorly known phenomena that occur in the earth's atmosphere, namely, celestial elves, sprites and streams
