The jet stream does not flow straight — it meanders in giant planetary Rossby waves, driven by the Earth's rotation varying with latitude. These waves carry weather systems around the globe and, when they grow large and stall, lock in heat waves, cold snaps, and floods. A few long waves circle the whole hemisphere.
