Temperate Rain Forests are coniferous or broadleaf forests that occur in the
mid-latitudes in areas of high rainfall.
Temperate rain forests are distinguished from other temperate forests by a
few factors:
Rainfall: high rainfall (minimum 2,000-3,000 mm/year, depending on latitude), usually from moisture-laden winds off the ocean.
Relative proximity to the ocean: temperate rain forests depend on the proximity to the ocean to moderate seasonal variations in temperature,creating milder winters and cooler summers than continental-climate areas.

Many temperate rain forests have summer fogs that keep the forests cool and moist in the hottest months.

Coastal mountains: temperate rain forests occur where mountains ranges are close to the coast; coastal mountains increase rainfall on the ocean-facing slopes.
