Longcheng Station: The Mystery of the Endless Nights and Days
The Location and Climate of Longcheng Station
Located in the eastern part of China's Antarctic territory, Longcheng Station is a Chinese scientific research station that was built in February 1992. It is situated in the Princess Elizabeth Land, on the Amery Ice Shelf, and it serves as an important station for environmental monitoring, logistics support, and scientific research. Longcheng Station is also one of the four Chinese Antarctic stations that is equipped with an astronomical telescope, which makes it an ideal location for studying celestial phenomena.
The Mystery of the Endless Nights and Days
One of the most intriguing questions about Longcheng Station is whether or not it experiences the phenomenon of polar night and polar day, more commonly known as the aurora and midnight sun. Polar night is a period of time in which the sun never rises above the horizon, and it lasts for several months. On the other hand, polar day is a period of time in which the sun never sets below the horizon, and it also lasts for several months. The phenomenon is caused by the tilt of the Earth's axis, and it can only occur in polar regions.
However, Longcheng Station is located outside the polar circle, which means the station is too far north to experience the polar day and too far south to experience the polar night. Therefore, it does not experience the famous \"endless nights and days\" that are characteristic of polar regions. At the station, the sun sets below the horizon during the winter and rises above it during the summer, just like any other location in the world.
Other Phenomena Observed at Longcheng Station
Although Longcheng Station does not experience the aurora or the midnight sun, there are still many other fascinating phenomena that can be observed at the station. Due to its unique location, the station experiences extreme weather conditions, with temperatures ranging from -40°C to -5°C. The station is also subject to high winds and blizzards, which can create dangerous conditions for the researchers who work there.
Another phenomenon that can be seen at Longcheng Station is the unique cloud formations that occur over the Amery Ice Shelf. Due to the cold temperatures and high humidity, the clouds can take on strange and eerie shapes that are unlike anything seen in other parts of the world. These clouds are often called \"polar stratospheric clouds,\" and they are responsible for the famous \"nacreous clouds\" that are sometimes seen in polar regions.
Overall, Longcheng Station is an invaluable resource for scientists and researchers who are interested in studying the unique features of Antarctica. Although the station does not experience the polar night or the polar day, it is still an ideal location for studying other important phenomena, such as extreme weather conditions and cloud formations. As such, Longcheng Station is an important player in the global scientific community, and it will continue to be an important research station for many years to come.
