What do meteorologists mean by the phrase “a piece of energy”?
The unfortunate term “piece of energy” is a misnomer too often used in broadcast meteorology. While there may be some kinetic energy of the moving air involved, “piece of energy” gives little information to the viewer or listener. What the meteorologist is talking about is a spin in the atmosphere, often evident on a satellite loop, that is enhancing upward motion of air. This upward motion then leads to condensation, clouds and often precipitation. The term “piece of energy” is sometimes used in conjunction with “upper-level disturbances.” Learn more about this term on this USA TODAY resource page.
