Web23 sep. 2024 · Adapted from Figure 3a in Lee et al. (2024). The speed of the jet stream at aircraft cruising altitudes – around 250 hPa or 34,000 feet – ultimately depends on how the two competing effects of climate change add up. If the lower-level tug wins, the jet weakens, but if the upper-level tug wins, it strengthens. The strongest jet streams are the polar jets around the polar vortices, at 9–12 km (5.6–7.5 mi; 30,000–39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10–16 km (6.2–9.9 mi; 33,000–52,000 ft).
