“Wetter rohr in niederbayern” translates to “weather pipe in lower Bavaria” and refers to a traditional method of weather forecasting in the Lower Bavaria region of Germany. It involves observing the behavior of water flowing through a pipe or channel to predict upcoming weather conditions.
The “weather pipe” is typically a hollowed-out tree trunk or a metal pipe installed at an angle. Water is allowed to flow through the pipe, and the way it flows is observed to make predictions about the weather. For example, if the water flows smoothly and steadily, it is said to indicate good weather. If the water is choppy or turbulent, it may indicate rain or storms. The length of time it takes for the water to flow through the pipe can also be used to predict the duration of the upcoming weather conditions.
