Which conditions are associated with the issuance of moderate turbulence AIRMETs?

Moderate turbulence AIRMETs are issued specifically when turbulence can be expected to affect flight operations significantly but does not reach severe levels. One of the primary conditions linked to these AIRMETs is the presence of thunderstorms, particularly unorganized ones.

Thunderstorms are inherently associated with turbulent air due to their convective nature, which generates vertical currents. Even if these storms are unorganized, the updrafts and downdrafts can cause moderate turbulence in their vicinity, impacting aircraft flying nearby. The turbulence associated with these conditions is critical for pilots to consider as it may affect aircraft stability and performance.

In contrast, clear conditions typically do not lead to turbulence or the necessity for an AIRMET regarding moderate turbulence, as there are no significant weather phenomena occurring to cause it. High altitude winds might influence turbulence, but they are not alone sufficient to warrant a moderate turbulence AIRMET unless connected with more significant weather systems like thunderstorms. The absence of significant weather issues implies a stable atmosphere, which would not result in turbulence necessarily.
