Editing Valdivian temperate forests (section)

===Climate===
Since the forest is located at around 40 degrees south, it is strongly influenced by the [[westerlies]]. The water vaper held by the westerlies condenses as they encounter the [[Windward and leeward|windward slope]] of the [[Chilean Coast Range]] and the [[Andes]], create [[orographic rainfall]]. Average annual precipitation varies from 1,000 mm at the northern edge of the ecoregion to more than 6,000 mm per year in the south.<ref name = wwf/> The northern portion of the ecoregion has a [[Mediterranean climate|Submediterranean climate]], with rainfall concentrated in the winter months. This seasonality decreases towards the south.<ref name = wwf/>

Average annual temperatures are fairly uniform within the area, especially at coastal locations where annual temperature differences between localities never exceed 7 °C.<ref name=arroyoetal95/> The northward-flowing oceanic Humboldt Current creates humid and foggy conditions near the coast. In the summer the temperature can climb to 16.5 °C (62 °F), while during winter the temperature can drop below 7 °C (45 °F).<ref>Di Castri F di & E. Hajek 1976.

The tree line is at about 2,400 m in the northern part of the ecoregion (35° S), and descends to 1,000 m in the south of the Valdivian region.<ref name = wwf/>
