Bergen in Norway and Snowdonia in Wales share a common climate trait: high annual rainfall. Discover the meteorological mechanics of orographic precipitation.
How Rising Sea Winds Create Clouds
Moist winds from the Atlantic or North Sea hit coastal hills and are forced upward. As the air rises, it expands and cools, forcing moisture to condense into heavy clouds.
The Rain Shadow Effect on Leeward Slopes
Once the air crosses the peaks and descends, it warms up and dries, creating a 'rain shadow' zone on the opposite side of the mountain chain.
