What does the abbreviation "KT" stand for in a weather report?

The abbreviation "KT" stands for "Knot," which is a standardized unit of measure for wind speed commonly used in aviation and meteorology. One knot is equal to one nautical mile per hour, making it particularly useful for air and maritime navigation, where distances are often measured in nautical miles. Using knots provides a consistent means for pilots and meteorologists to convey wind speeds, which are vital for safe flight operations and weather forecasting.

Other options, while related to measurements or concepts, do not pertain to the context of wind speed in weather reports. For instance, kilometers per hour is a unit of speed but is not used in aviation contexts, and kilograms of force pertains to weight and not wind measurements. Kinetic temperature could suggest a theoretical temperature measure but does not apply to meteorological wind speed reporting. Thus, "KT" specifically and accurately indicates wind speed in knots.
