Editing Subarctic climate (section)

===Precipitation===
Most subarctic climates have little precipitation, typically no more than {{convert|380|mm|abbr=on}} over an entire year due to the low temperatures and [[evapotranspiration]]. Away from the coasts, precipitation occurs mostly in the summer months, while in coastal areas with subarctic climates the heaviest precipitation is usually during the autumn months when the relative warmth of sea vis-à-vis land is greatest. Low precipitation, by the standards of more temperate regions with longer summers and warmer winters, is typically sufficient in view of the very low [[evapotranspiration]] to allow a water-logged terrain in many areas of subarctic climate and to permit snow cover during winter, which is generally persistent for an extended period.

A notable exception to this pattern is that subarctic climates occurring at high elevations in otherwise temperate regions have extremely high precipitation due to [[orographic lift]]. [[Mount Washington (New Hampshire)|Mount Washington]], with temperatures typical of a subarctic climate, receives an average rain-equivalent of {{convert|101.91|in|mm|1}} of precipitation per year.<ref>[http://www.mountwashington.org/weather/normals.php Mount Washington Observatory: Normals, Means, and Extremes, Retrieved July 1, 2009.]</ref> Coastal areas of [[Khabarovsk Krai]] also have much higher precipitation in summer due to orographic influences (up to {{convert|175|mm|in}} in July in some areas), whilst the mountainous [[Kamchatka]] peninsula and [[Sakhalin]] island are even wetter, since orographic moisture isn't confined to the warmer months and creates large [[glacier]]s in Kamchatka. [[Labrador]], in eastern Canada, is similarly wet throughout the year due to the semi-permanent [[Icelandic Low]] and can receive up to {{convert|1300|mm|in|0}} of rainfall equivalent per year, creating a snow cover of up to {{convert|1.5|m|in|0}} that does not melt until June.
