What to Expect

The Phoenix to Charleston route, heading east for about 4 hours, is interesting from a turbulence perspective. You'll begin by crossing the Mojave and Sonoran Deserts, where thermal turbulence caused by rising hot air can create some initial bumps. As you move eastward, you'll encounter the Southern Rockies, and mountain wave turbulence becomes a possibility. Then you'll fly over Tornado Alley, where severe convective turbulence from thunderstorms is common, especially in certain seasons. Further along the route, the Ozark Plateau and Mississippi Valley can bring more convective turbulence. Before reaching Charleston, you'll cross the Southeast Interior (another area prone to convective activity) and the Southern Appalachians, where mechanical turbulence from the mountains can occur. Pilots are well-versed in navigating these conditions and use weather forecasting to plan the smoothest possible flight path. It's all part of a normal flight.

The Phoenix to Charleston route passes over the Southern Rockies in New Mexico and southern Colorado. While somewhat lower than the peaks to the north, these mountains still produce notable mountain wave turbulence, particularly when strong southwesterly winds aloft align perpendicular to the ridgeline.

Turbulence Factors on This Route

• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• Severe Convective Turbulence: Tornado Alley supercells produce some of the most intense convective turbulence in North American aviation.
• Mechanical Turbulence: The Southern Appalachians produce terrain-induced chop, especially during strong wind events and summer convection over the ridgeline.

When Is This Route Bumpiest?

The winter and late fall are usually the calmest times to fly this route. The summer, while often associated with smooth conditions, can also bring afternoon thunderstorms that cause convective turbulence. The late winter, spring, and early summer tend to be bumpier, as these are seasons of increased convective activity and storm systems affecting the areas you'll be flying over, particularly around Tornado Alley. Be aware that mountain wave turbulence near the Rockies can occur any time of year, but is more common with specific wind patterns.

Tips for This Flight

Opting for a morning flight is often your best bet for a smoother ride on this route, as atmospheric conditions tend to be more stable earlier in the day. Any turbulence you encounter will likely feel similar to driving on a slightly bumpy, unpaved road. Choosing a seat over the wing provides a more stable experience during turbulence. Remember to stay hydrated by drinking plenty of water, as this can help you feel more relaxed and grounded. Focus on slow, deep breaths, and remind yourself that the pilots are expertly trained to handle these conditions; they want you to have a safe and comfortable flight.
