The taiga experiences relatively low precipitation throughout the year (generally 200–750 mm (7.9–29.5 in) annually, 1,000 mm (39 in) in some areas), primarily as rain during the summer months, but also as snow or fog. Snow may remain on the ground for as long as nine months in the northernmost extensions of the taiga biome. [25]
Fire is the dominant type of disturbance in boreal North America, but the past 30-plus years have seen a gradual increase in fire frequency and severity as a result of warmer and drier conditions. From the 1960s to the 1990s, the annual area burned increased from an average of 1.4 to 3.1 million hectares per year.
The Cook Inlet taiga is a taiga and boreal ... This coast has a gentle landscape and a relatively mild climate for Alaska with 380–680 mm of rainfall per year. [1]
The island is wet, with monsoon characteristics. Precipitation is highest in the summer. Precipitation various from 600 to 1,200 mm/year, depending on location, altitude, etc. [7] The Poronaysky Nature Reserve in the southeast of the island gets more than 100 rainstorms per year, average precipitation 600 mm/year, with frequent fog in the summer.
Average rainfall in the eastern side of the ecoregion is 550mm per year, rising to 750mm in the centre (near Lake Nipigon for example), up to 900mm in the west. Specific areas include Lake Nipigon and Big Trout Lake (Ontario) . [ 2 ]
Known as the "Ussuri taiga," this region of Russia has long, cold winters and fairly mild summers to go along with a mean precipitation of 800–1000 mm per year. [2] During the summer and fall, a monsoonal influence brings tropical storms and typhoons coming from the southeast, resulting in substantial rainfall. [2]
This climate is characterized by mild summers (only 1–3 months above 10 °C (50.0 °F)) and cold, snowy winters (coldest month below −3 °C (26.6 °F)). [ 6 ] [ 7 ] Annual precipitation averages 200–400 mm/year across most of the region, reaching 500 mm/year in the south.
With mountains blocking the passage of moisture-laden air masses into the region, typical annual precipitation averages 250 to 300 mm throughout the ecozone, [5] resulting in a dry climate. [6] Winters are long, dark and extremely cold, with mean January temperatures between -25 and -30 °C. [ 5 ]
