Instead, a new study suggests, the phenomena occur when four types of slow - moving, high - altitude atmospheric waves merge over a small region and, in turn, temporarily drive a 10 - fold - or - stronger brightening of an ever - present glow in the upper atmosphere (green layer in the image above).

The ambiance of upper - atmospheric diffusion is especially palpable in such installations from the 1990s as St. Elmo's Breath (1992), and in a recent series of wide and tall glass panels animated with dissolving waves of color.

Long - term trends in the upper atmosphere - ionosphere are a complex problem due to simultaneous presence of several drivers of trends, which behave in a different way: increasing atmospheric concentration of greenhouse gases, mainly CO2, long - term changes of geomagnetic and solar activity, secular change of the Earth's main magnetic field, remarkable long - term changes of stratospheric ozone concentration, and very probably long - term changes of atmospheric dynamics, particularly of atmospheric wave activity (Lastovicka 2009; Qian et al. 2011; Lastovicka et al. 2012).

By using an idealized heating to force a comprehensive atmospheric model, the large negative anomalous latent heating associated with the observed deficit in central tropical Pacific rainfall is shown to be mainly responsible for the global quasi-stationary waves in the upper troposphere.
