waviness

It showed areas where the carbon fibre layers had separated - a known problem called delamination - as well as wrinkles, waviness and voids within its structure.

The cold front was following a classic waviness in the jet stream — the atmospheric rivers that move weather systems — seen in La Nina winters, Gensini said.

And it states that the Italian supplier had two formal notices of missed inspections for surface waviness in 2018 and two more in 2020.

If the jet stream does indeed shift north in the coming decades, less waviness might be expected, he said.

Some scientists have linked jet stream disruptions such as this, often referred to as “waviness,” to climate change in the Arctic, although that is still a subject of debate.
