Which code represents drizzle in meteorological reports?

The code that represents drizzle in meteorological reports is "DZ." In meteorological terms, drizzle is characterized by very light rain formed by small water droplets, typically less than 0.5 millimeters in diameter. The abbreviation "DZ" specifically indicates this light precipitation, distinguishing it from heavier forms of precipitation like rain, represented by "RA."

Understanding the codes used in meteorological reports is crucial for air traffic controllers, as they need to interpret weather conditions accurately to ensure safe and efficient aircraft operations. For instance, "FG" refers to fog, which can significantly impact visibility, and "SH" indicates showers, which may involve sudden changes in intensity. Knowing the correct codes allows air traffic controllers to make informed decisions regarding flight operations and safety based on current weather conditions.
