“Wetter auf dem Brocken” refers to the weather conditions on the Brocken, the highest peak in the Harz Mountains of central Germany. It is known for its harsh and unpredictable weather, with frequent fog, rain, and storms. The average annual temperature on the Brocken is only 2.9 C (37.2 F), and the average annual precipitation is 1,500 mm (59 in).
The weather on the Brocken is influenced by its elevation and its location in the path of the prevailing westerly winds. The mountain acts as a barrier to the moist air from the Atlantic Ocean, causing it to condense and fall as rain or snow. The Brocken is also often shrouded in fog, due to the condensation of moisture from the surrounding air. In winter, the Brocken is frequently covered in snow and ice.
