What is the perennial dominant wind direction in Gulang County, Wuwei City, Gansu Province?
In spring, with the enhancement of solar radiation, the temperature rises gradually, but due to the frequent cold air activities in spring, it is often accompanied by severe weather such as strong wind, sandstorm, cold wave, frost and spring drought. In summer, the temperature is high, the evaporation is large, and there are often severe weather such as drought, local rainstorm or heavy rainstorm and hail.
The main large-scale weather systems affecting Gulang in summer are Qinghai-Tibet high and western Pacific subtropical high. Because this area is located in the northeast of Qinghai-Tibet Plateau, sunny and hot weather often occurs within the control range of Qinghai-Tibet high pressure. When the large and medium-sized high pressure moves to the eastern plateau, it weakens and disappears or merges into the subtropical high in the eastern continent, and the low pressure trough after it often causes regional heavy rain or heavy rain.
In autumn, with the strengthening of cold air in the north, the solar radiation weakens and the temperature drops rapidly. Frost first appeared in Pingchuan in late September. The daily average temperature dropped from about 20℃ in late August to about 10℃ in mid-September. /kloc-The average temperature in October is 8℃ to 9℃ in Pingchuan, about 5℃ in the foothills, and only about 0.5℃ to 2.0℃ in the mountainous areas between 2,700 meters and 3,000 meters above sea level in Central Asia.
In winter, controlled by the high pressure of Mongolian Plateau and the Siberian cold current, the climate is cold and dry, with little rain and snow. The monthly average minimum temperature is below 0℃, with five months in Pingchuan District (June of the first year 1 to March of the second year) and seven months in foothills and middle and low mountains (June of the first year1to April of the second year).
