Meteorological Calendar 2024 - Atmospheric optical phenomena

Colourful sunrises and sunsets enchant us time and again. But the sky has many more fascinating light spectacles to offer. For instance, what are the impressive rings you sometimes see around the sun? You may have wondered why some clouds still shine brightly even in the late evening twilight.

The Meteorological Calendar 2024 is dedicated to these optical phenomena in the atmosphere.

In keeping with the main theme of this calendar, the front pages feature impressive images of optical atmospheric phenomena and on the reverse sides, in addition to an overview, you will find articles about twilight colours and apparent distortions of the sun on the horizon. We tell you about green flashes and how you can observe them. Of course, you can also find out the physical principles behind these phenomena. Read how optical phenomena are simulated and what insights they provide.
