Main Meteorological Conditions of Winter Rime in Gurbantunggut Desert
First, the temperature difference between day and night is large.
On the west side of Fuhai County, there is Wulong Ancient Lake, the second largest lake in Xinjiang. Rime often appears in the desert area around Wulong ancient lake, which is a desert area with large temperature difference between day and night in winter.
Second, the water vapor is sufficient.
At the beginning of 1 1 every year, Lake Ulungu begins to freeze, and the fishing season is June 5438+February to March. The ice thickness of the lake is 1 m, and the snow area is about 30 cm. Lake Ulungu enters the "winter fishing" season from May 5438 to February every year. In winter, dragnet fishing on ice is a traditional fishing method in Lake Ulungu, and the scene is spectacular.
Third, there must be plants that can be attached.
First of all, there are unique creatures here that are not found in other deserts. In addition to all kinds of desert shrubs and ephemeral plants, there are rare bryophytes in the desert. Moss and other plants have very strong nitrogen fixation, which can gradually transform sand dunes into soil.
Second, the snow and ice weather cycle is long, the snow lasts for a long time, and the melting of snow increases soil moisture.
It is the special geographical environment and climatic conditions, together with unknown plant communities such as moss, that have played an unimaginable role, thus changing the ecology of the desert. In addition, in recent years, scientific sand control, with the continuous recovery of the ecological environment, the Gurbantunggut desert is becoming more and more green.
This desert, far from the ocean, has become a rare ungulate paradise in the northwest, the largest winter pasture in Altay in the long winter, and the most common rime landscape in the desert.
