K-index (meteorology)

The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer."^[1] It was developed by the American meteorologist Joseph J. George, and published in the 1960 book Weather Forecasting for Aeronautics.^[2]
