Where are the Zhongshan Station and the Great Wall Station in China at the South Pole and the North Pole?
Zhongshan Station was established in February of 1989, located at Lasman Mountain in the East Antarctic continent, with an altitude of14.9 m. Since its establishment, it has been included in the Antarctic Basic Weather Network (ABCN) of the World Meteorological Organization (WMO), the Antarctic Basic Climate Observing System Ground Station (ABSN) and the Global Climate Observing System Ground Station Network (GSN). The station is covered with snow in winter and bare gravel in summer. Because it is located in the Antarctic circle, there are 55 days of polar days (1late October to1early October) and 58 days of polar nights (late May to early July) every year. The Great Wall Station is located at the edge of the Antarctic convergence zone of the polar westerly belt, specifically in the southwest pole, king george island of the Antarctic Peninsula. There are frequent cyclone activities in polar regions all year round, and the weather conditions in winter and summer are complex and changeable. Winter is dominated by snowstorms and low temperature days, and summer is dominated by fog, rain and snow days. The rainy weather in Great Wall Station accounts for 90.5%, and the annual average relative humidity is 89%. Sunny weather usually occurs after the cyclone passes through the border and lasts for 3-5 days, mainly due to the development and southward extension of the South American high ridge, while the Antarctic continental high is relatively stable, forming a saddle-shaped field on the Antarctic Peninsula. The weather systems affecting Great Wall Station mainly include polar cyclone, Antarctic continental high and South American high. The most critical weather system for disastrous weather at Great Wall Station is polar cyclone. In summer, 1 cyclone invades king george island area of Antarctic Peninsula every 3-4 days, and the average number of cyclones affecting Great Wall Station every month is 6-8. The intensity of cyclones in winter is stronger than that in summer, with an average of 5-7 cyclones per month, and the moving path of cyclones is slightly north-south than that in summer. When a polar cyclone hits King George Island, the Great Wall Station will have different weather, mainly because the Great Wall Station is located in different positions of the cyclone. For example, the Great Wall Station is located in the northeast of the cyclone, which is affected by the northerly airflow and the northwest airflow. A large amount of warm and humid air raises the temperature of Great Wall Station, resulting in rain or sleet; Located in the southeast or south of the cyclone, affected by the southeast or southerly airflow, the weather is mainly cooling, snowfall and strong wind.
