What does 'SCT' stand for in weather observations?

In weather observations, 'SCT' stands for 'Scattered', which is a term used to describe cloud cover. Specifically, it indicates that clouds cover between 3/10 and 4/10 of the sky. This classification helps pilots and meteorologists understand the extent of cloud cover and assess its impact on flying conditions.

The use of 'scattered' is significant in weather reporting as it provides a clear indication of visibility and potential weather patterns. Understanding cloud coverage is essential for safe flight operations, as it influences both visual flight rules (VFR) and instrument flight rules (IFR).

The other terms do not reflect the correct definition within the context of weather observations. For example, 'scant' typically refers to a small quantity, which doesn’t specifically relate to cloud cover. 'Separated' and 'static' also do not describe cloud formations or visibility conditions in a weather context. Therefore, understanding that 'SCT' means 'Scattered' is crucial for accurate weather interpretation in aviation.
