I believe it runs north & south, to my understanding odd numbers runs N & S,
while even numbers runs E & W.
One country that would be smaller than England are the Maldives, since they are a serious of islands that are only roughly 300 square kilometers in area.
It is difficult to make generalizations about the highland climate zone because little research has been done at high altitudes, and data is not readily available. Without actual data, it would be wrong to make any generalization about the highland climate zone.
Hope this helps
