I want to know the answer to the following question:
What is sufficient to divide the weather patterns in Europe into a wet north and dry south?
All the background I'm provided with is that "The effect of mountain chains on prevailing winds is to carry warm air belonging to the lower region into an upper zone, where it expands in volume at the cost of a proportionate loss of temperature, often accompanied by precipitation in the form of snow or rain.". Is that enough to answer the question?
Answer: no
