Full Form of FZD
What is FZD?
Freezing drizzle (FZD) is a meteorological phenomenon where drizzle falls as liquid droplets that freeze upon contact with surfaces at or below freezing temperature, forming a thin layer of ice. In India, FZD is relatively rare but occurs in high-altitude regions such as the Himalayas, particularly in Jammu & Kashmir, Himachal Pradesh, and Uttarakhand during winter months. It is reported in aviation weather reports (METAR) and synoptic codes, where it is a hazard for aircraft icing and slippery roads. The India Meteorological Department (IMD) uses FZD in their weather bulletins to alert authorities about potential disruptions. Understanding FZD is important for pilots, road transport departments, and disaster management teams. For students appearing in exams like UPSC or SSC, knowledge of basic weather codes including FZD may appear in Geography or General Science sections. FZD differs from freezing rain in droplet size, with drizzle being smaller and more likely to freeze instantly upon impact, making it a subtle but dangerous winter weather condition.

FZD — frequently asked questions
What is the full form of FZD?
FZD stands for Freezing Drizzle, a weather term used to describe liquid drizzle that freezes on contact with cold surfaces.
Where in India does freezing drizzle occur?
Freezing drizzle mostly occurs in the higher altitudes of the Himalayas, such as Jammu & Kashmir, Himachal Pradesh, and Uttarakhand during winter.
Is FZD dangerous for flights?
Yes, FZD causes aircraft icing, which can reduce lift and impair control, making it a significant hazard for aviation operations in cold regions.
