Detailed explanation-1: -Temperatures of the boreal forest found below tundra region are cold and can last for eight months between the months of October to May. The average temperature is estimated between-30°F and-65°F. Also, an average of 16-39 inches of snowfall has been recorded in the forest during winter.

Detailed explanation-2: -Taigas are thick forests. Coniferous trees, such as spruce, pine, and fir, are common. Coniferous trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones. While deciduous trees of temperate forests lose their leaves in winter, conifers never lose their needles.

Detailed explanation-3: -During the summer in the boreal forest, warm, moist air from the Pacific air mass moves north, bringing warm weather and rain. During the winter, cold, dry air from the Arctic air mass pushes south, into the boreal forest, causing the cold, dry winters.

Detailed explanation-4: -Because of earth’s tilt, the taiga is turned away from the sun in the winter. Less of the sun’s radiation reaches the ground to warm it up. Winter, with it’s freezing cold temperatures, lasts for six to seven months. Summer is a rainy, hot and short season in the taiga.

Detailed explanation-5: -The boreal forest has cold winters and warm summers. Typical temperatures range from 21 °C in summer to-54 °C in winter. The precipitation in this biome is moderate. It ranges from 200 to 600 mm per year.
