Weather in The Tundra/ Meteorologist

Tundras have very long and harsh winters, with temperatures in negatives as a high. The growing season ranges from 50 to 60 days. During the growing season,which is about 6-10 weeks, the temperature warms to a sustainable climate. during the summer, it is still very cold. it will never get above 65 degrees. The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F) which enables this biome to sustain life. Rainfall may vary in different regions of the tundra. Yearly precipitation is 6-10 in(15-25 cm) including melting snow. There is a permanently frozen layer of ice 10 in-3 ft. The wind blows average 30-60 mph. The summer only last 6-10 weeks. The summer warms up the permafrost, which causes lots of flowers to bloom. There is a low air pressure.  Humidity is average 85%, or high humidity. The weather patterns throughout the year are a 6-10 week summer with usually 35-50 degrees, and the rest of the year is a harsh winter with an average temperature of -30 and below. This effects the organisms in the tundra because most of the animals grow a thick coat of fur to protect them from the harsh temperatures. Also, in the summer, the animals shed their fur, and flowers and plants grow. Then the plants die, and the animals grow their fur back for the next winter.
