Vinil7 [7]

Months with higher temperature have more rainfall.

Explanation:

From the presented graph, we can see that all three parameters are following a same trend. When the maximum temperatures increase, the minimum temperatures increase too, and the rainfall increases as well. When the maximum temperatures decrease, the minimum temperatures decrease, and the rainfall decreases too.

There is a simple explanation for the connection of higher temperature and more rainfall in Scotland. Scotland is located on an island, thus it is heavily influenced by the sea. When the temperature is higher, the humidity is higher, and in accordance to that more rainfall occurs. When the temperature is lower, the humidity is lower, so there is less rainfall, or instead of rainfall the precipitation can be manifested as snowfall.
