Which reports provide information about turbulence?

The correct choice identifies SIGMETs, AIRMETs, and CWAs as the reports that provide critical information about turbulence.

SIGMETs, or Significant Meteorological Information, specifically address hazardous weather conditions that can impact aviation, including turbulence caused by thunderstorms, severe turbulence, and clear air turbulence. AIRMETs, or Airmen's Meteorological Information, are broader and are issued for less severe weather conditions but still provide valuable warnings regarding turbulence that could affect smaller aircraft. CWAs, or Center Weather Advisories, are real-time advisories that provide information on current weather phenomena, including turbulence, specifically tailored for the use of air traffic controllers and pilots.

These reports are essential for flight planning and safety, providing pilots with timely updates on weather conditions that could directly impact their routes. They ensure that pilots are aware of potential turbulence, enabling them to take necessary precautions and make informed decisions during flight operations.

In contrast, NWS Notices, Local Weather Articles, and Flight Path Updates may not focus explicitly on turbulence or may provide less comprehensive and actionable data regarding turbulent conditions.
