What I found is, is Vancouver a temperate rainforest climate? What's going on here?

Rainforest is considered as one of the masterpieces of environmental art among various natural ecosystems on the earth. Rainforests are divided into tropical rainforests and temperate rainforests by location. Among them, the name of "tropical rain forest" is more well known. Tropical rainforests are concentrated in South America, Southeast Asia and Africa. Its rich species play an important role in maintaining the global ecological balance. However, human destructive activities, such as logging, farming and grazing, make it face a devastating threat. At present, less than half of the remaining tropical rain forests are rapidly decreasing at the rate of 129500 square kilometers per year.

Differences in temperate rainforests

In fact, although temperate rainforests are not as widely distributed and well known as tropical rainforests, they are also fragile, complex and fascinating. Mainly distributed in the Olympic Peninsula of Washington State, southeastern Alaska and the west coast of vancouver island. It also exists in Chile in the southern hemisphere and Tasmania in Australia. Temperate rainforests are similar to tropical rainforests in some respects, such as tall trees, lush shrubs and numerous epiphytes, but there are also many differences between them. According to the report of the National Academy of Sciences, a representative 4-square-mile tropical rain forest contains about 65,438+000 species of reptiles, 65,438+025 species of mammals and 400 species of birds. In contrast, there are far fewer species in temperate rainforests. This is because many temperate species died out during the ice age, while tropical species continued to develop and evolve during the period of 1 100 million years. But temperate rainforests have more biomass, that is, the total biomass per square mile, than tropical rainforests. Most animals in temperate rainforests live on the ground, quiet and not annoying. Different from the tropical rain forest, there are noisy monkeys, birds and frogs, as well as dangerous and disgusting snakes, leeches and spiders. In short, temperate rainforests are more temperate.

Terrain "controls" the temperate rainforest climate.

Abundant precipitation is an important condition for the formation of rainforest. Most of the annual precipitation in tropical rainforests is around 2500mm. For temperate rainforests, this usually happens only in coastal mountainous areas between 45 and 55 degrees latitude. Temperate rainforests are characterized by warm winters and cool summers, and the temperature in winter is rarely lower than zero degrees Celsius, which provides a good natural environment for the survival and development of animals and plants, especially in the western part of the Huohuo, Kuntes and Knut valleys along the Olympic Peninsula, and their conditions are superior to those in temperate rainforests in Alaska and Canada further north. The situation of the Olympic Peninsula "vividly" illustrates the role of topography in the formation of temperate rain forest climate. The Olympic Mountain on the peninsula is nearly 2438 meters above sea level. The annual precipitation in this area recorded by Winoch Oxburg weather station on the west side of the mountain range is 4,688 mm in 193 1 year, and the annual precipitation in Sekum city at the foot of another mountain is only 80 kilometers away from the weather station, but it is only 406 mm. Scientists' explanation is that when the prevailing westerly wind blows from the open Pacific Ocean to the peninsula, it is blocked by tall mountains and rises. The airflow cools and condenses in the rising process, thus forming precipitation on the windward slope. But on the other side of the mountain range, the situation is just the opposite. The air sinks, the temperature rises, it is not easy to condense, and there is less precipitation. Therefore, the annual precipitation at the peak of Olympus at an altitude of 29 17 meters can be as high as 5080 mm, while Sekum City is in the so-called "rain shadow area" (the area with little precipitation on the back of the mountain), and the annual precipitation is only equivalent to the semi-arid prairie east of the Rocky Mountains.

Vancouver is called "the paradise of the west" by many people.

Vancouver is often the most livable city in the world, which is inseparable from its unique geography and climate.

Vancouver is located in the southwest of British Columbia. The so-called Vancouver actually refers to the large temperature zone, which is connected by more than a dozen cities. Because these cities surround Vancouver and radiate outward with Vancouver as the center, it is customary to take Vancouver as a general term. To the west, Vancouver is connected with the Pacific Ocean through the george strait, and not far from the south is Washington State. There is Hengjia No.1 Highway connecting the Philippines and Saya in the east, and mountains and countless islands in the north.

Vancouver has a latitude of 49 degrees, but it has a typical temperate rainforest climate. Summer is sunny and dry, with long sunshine time; It is dark and rainy in winter, and the sunshine time is short. The temperature in summer is generally around 25 degrees, rarely exceeding 30 degrees; Winter is above zero, with continuous rain. Although there is no lack of heavy snow, the snow melts quickly and there is little snow in cities.
