Nashville, United States
BNA (Nashville, United States) sits at 36.12°N, 86.68°W, 599 ft elevation — inland.
Major airport serving Nashville, United States.
Computed from BNA's geography and climate
Nashville sits squarely under the mid-latitude-latitude jet, north of which most long-haul corridors run. Clear-air turbulence (CAT) at cruise is the most common source of bumps on departures from here, especially during December–February when the jet is at its strongest. Warm-season convection (June–August) drives the dominant turbulence pattern from BNA — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures.
Climbout is usually unremarkable — most turbulence on flights from Nashville occurs at cruise rather than immediately after takeoff.
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise. Summer (June–August) is peak thunderstorm season — convective turbulence is the dominant warm-season risk.

Nashville International Airport is best described as a mid-latitude jet-exposed hub. Nashville sits squarely under the mid-latitude-latitude jet, north of which most long-haul corridors run. Clear-air turbulence (CAT) at cruise is the most common source of bumps on departures from here, especially during December–February when the jet is at its strongest. Warm-season convection (June–August) drives the dominant turbulence pattern from BNA — afternoon thunderstorm cells are routed around but their wake turbulence and gust fronts can still affect arrivals and departures.
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise. Summer (June–August) is peak thunderstorm season — convective turbulence is the dominant warm-season risk. Peak turbulence window: November–February (strong jet). Typically calmest: May–September.
We combine live NOAA Aviation Weather Center data (PIREPs, SIGMETs, AIRMETs) with physics-based Ellrod and Richardson-number calculations derived from Open-Meteo pressure-level wind and temperature data. If a source is unavailable for a waypoint we show an em dash rather than invent a number.
