What does the code SS signify?

The code SS signifies a sandstorm in aviation meteorology. This code is used in weather observations to indicate significant blowing sand, which can impact visibility and create hazardous flying conditions. Sandstorms often arise in desert or arid regions when strong winds lift and suspend a large amount of sand in the air, reducing visibility and posing challenges for pilots and other aviation personnel.

When interpreting weather codes, it's important for pilots and air traffic controllers to understand the specific meanings attached to various codes for safe navigation and operational decision-making.

Understanding the context and implications of this code helps in effective flight planning and safety management, especially in regions prone to such weather phenomena.
