In aviation terms, what does "DZ" represent?

In aviation meteorology, "DZ" stands for drizzle. This term is used to describe a specific type of precipitation characterized by very light rain in which the droplets are smaller than what you would typically find in moderate or heavy rain. Drizzle consists of light water droplets that are usually less than 0.5 millimeters in diameter, resulting in a gentle, almost mist-like precipitation that can affect visibility and aircraft operations but typically does not create significant operational challenges. Understanding such terms is crucial for pilots and operators as they plan and execute their flights, ensuring they can respond appropriately to various weather conditions.
