Both the depicted and the «real» reflections take on the same characteristics of the horizontal waviness of the glossy enamel surface, making these shapes borne of the panels rather than being of a standard photographic image. (artzine.com)
They compared those events with changes in the Global Wind Oscillation (GWO) index, a collection of climate and weather information that measures atmospheric angular momentum, or the degree of waviness in the jet stream. (sciencedaily.com)
They also found a smaller cycle of waviness about every 200 years, Bowen said, although the margin of error in their records makes that finding less robust. (scientificamerican.com)
