Over the next 3 days, the eastern Mongolia-China border region will experience relatively low humidity, with mostly clear to cloudy skies and scarce precipitation. From October 24 to 25, an upper-level trough will shift eastward and affect Mongolia (Figure 2).  Influenced by it, the eastern Mongolia-China border region will see northwest winds of force 3-4, with gusts of force 5-6 (Figure 3), and temperatures will drop by 3-5°C.
