FrostTauZyklen

FrostTauZyklen is a term used in cryospheric and architectural research to describe recurring cycles of frost formation and dissipation on surfaces where temperatures hover around the freezing point and moisture availability varies. The name blends the German word for frost with Zyklen, meaning cycles, and it is employed to distinguish these near-thaw–near-freeze patterns from simple, unidirectional freeze events.

The core idea behind FrostTauZyklen is that surface conditions can produce repeated layering of frost through alternating deposition and melting or sublimation within short time scales. When nightly temperatures drop just below 0 C and humidity is sufficient, frost forms. If daytime temperatures rise slightly above freezing or if radiant heating increases, the frost partially melts or sublimates, returning to a tenuous frost film that can reform in the following cycle. In some settings, dew formation and radiative cooling also contribute to the cycle, creating a dynamic balance between deposition and loss.

Typical environments where FrostTauZyklen may occur include tundra and alpine terrains, coastal areas with regular fog or mist, and urban microclimates where surfaces experience rapid temperature swings. The effect is often observable as alternating frost laminae on soil surfaces, rocks, or plant stems, and can influence soil structure, surface albedo, and weathering processes.

Methods to study these cycles combine surface temperature sensing, humidity monitoring, infrared thermography, and time-lapse photography. Understanding FrostTauZyklen helps assess impacts on frost heave, infrastructure durability, and ecosystem dynamics in regions experiencing pronounced near-freezing temperature fluctuations.
