  Name	Description
  Mediterranean	The distinctive climatic type which occurs around latitude 35 � N and 35 � S, and is associated with warm-temperate west coasts. Summers generally are hot and dry, winters mild to cool and rainy. The climate is strongly influenced by westerly air-streams in winter, and sub-tropical high pressure in summer. In the type area, the Mediterranean basin, there is a variety of climatic regions owing to the complex configuration of seas and mountainous peninsulas in the 3000km incursion into Eurasia. Annual rainfall is broadly 500-900 mm, but less in more continental locations.
  Temperate	A climate zone between the boreal in the north and the mediterranean in the south. A mid-latitude climate influenced from time to time by both tropical and polar air masses. Temperature criteria provide subdivisions into warm- or cold-temperate climates.
