The scales of conifer cones react to changes in humidity. In dry weather, the scales open outward to release seeds for dispersal by wind. Conversely, increased humidity causes the scales to close inward, protecting the seeds and preventing dispersal in less favorable conditions. Observing these changes can provide a basic, localized indication of impending weather shifts.
This natural hygrometer has been utilized for generations, particularly in traditional practices and folklore. While not as precise as modern meteorological instruments, observing conifer cone behavior offers accessible, readily observable insights into short-term atmospheric changes, potentially helpful for outdoor activities or in areas with limited access to technology. It provides a tangible connection to natural processes and the rich history of weather prediction.
