Which AIRMET type specifically relates to turbulence?

AIRMET Tango is the correct response as it specifically pertains to turbulence. AIRMETs, or Airman's Meteorological Information, are advisories issued by the National Weather Service to alert pilots about weather conditions that may affect aircraft operations. AIRMET Tango focuses on moderate turbulence, which can occur at any altitude, and is particularly relevant for pilots operating in general aviation and under visual flight rules.

Understanding AIRMETs is critical for flight safety, as they provide essential information on areas where turbulence is expected to impact aircraft performance. While AIRMET Sierra deals with IFR conditions due to ceilings and visibility, and AIRMET Zulu is concerned with icing conditions, these do not focus on turbulence specifically. AIRMET WA, which doesn't correspond to a standard type of AIRMET, can lead to confusion, but it is not an actual classification used for turbulence advisories. Hence, AIRMET Tango is the correct choice when specifically referring to turbulence.
