Weather Functions
The weather functions complement the Sun Clock with information about current and upcoming weather. Unlike the astronomical dial, they depend on external data and an internet connection.
The web app provides three weather views and up to three additional features:
- On the dial: a compact weather outlook for the next 4 hours
- Detailed weather: an hourly forecast covering 48 hours
- Long-range weather: a 9-day forecast together with 7 days of weather history
- Ongoing weather analysis: displays changes in the weather automatically
- Singularity monitoring: appears when a weather singularity is detected
- Phenological seasons: displays the current phenological season (Germany only)
The last two features are available only in the browser/PWA version, Astronomical Sun Clock, and are explained below.
Weather Singularities checks forecasts against regional rule sets for recurring seasonal weather patterns. An event is displayed only when the relevant rules match. The supplied rule sets currently cover Germany only, but you can create your own set for other regions:
Create Your Own Rules explains how to enter and test a custom JSON rule set in the web app, either exclusively or alongside the supplied regional rules.
Currently Germany only
Phenological Seasons provides an indication of the development of the biological year in Germany. It uses the current phenological season reported by the German Weather Service (DWD), together with regional reporting figures.
