Winds on an ultrahot planet challenge climate models

The ultrahot exoplanet WASP‑121 b has strong winds that transport material in different directions depending on the altitude in the planet’s atmosphere. High-resolution observations have mapped these winds for the first time, challenging the current understanding of atmospheric dynamics. The vertical placement of an exoplanet’s jet stream is not predicted by simulated climate systems.

Abstract

The ultrahot exoplanet WASP‑121 b has strong winds that transport material in different directions depending on the altitude in the planet’s atmosphere. High-resolution observations have mapped these winds for the first time, challenging the current understanding of atmospheric dynamics. The vertical placement of an exoplanet’s jet stream is not predicted by simulated climate systems.
