What is the phraseology used for unstable conditions producing multiple wind shear alerts?

• A. Wind shift sequence
• B. WIND SHEAR DETECTED; MULTIPLE ALERTS
• C. Wind shear alerts continuous
• D. MULTIPLE WIND SHEAR/MICROBURST ALERTS (specific alert or wind information)

Answer: (D)

Unstable conditions that cause more than one wind shear indication require a phrase that clearly states there are several alerts and what they pertain to. The best wording is to say there are multiple wind shear/microburst alerts. This communicates both the multiplicity and the specific hazards (wind shear and microbursts) in a concise, unambiguous way, which helps pilots and controllers understand that there isn’t just a single event to monitor but several, potentially escalating as atmospheric conditions evolve.

The other phrasings either imply something different (like a sequence of wind shifts rather than alerts), or sound awkward or incomplete for indicating multiple events. The selected phrase is direct, standardized in intent, and immediately informs all parties of the heightened, repeated risk.
