This is a poem written more than 600 years ago by officials of the Ming Dynasty in China after they went to Central Asia. Snow in summer means that this place is at least in the temperate zone. The poem "Four seasons often feel cold, but I don't know spring in June" means that I often feel cold all year round, and June is summer, but I still can't feel the phenological characteristics of spring. It shows that this place is very cold, because Central Asia lives inland and belongs to temperate continental climate.
The temperature in winter is extremely low, because the thermal properties of land and sea are too different, which is close to the source of winter wind. In summer, the temperature in Uzbekistan is low because of its high altitude. Moreover, the westerly belt brings water vapor through the Caspian Sea and the Black Sea, and the terrain rises, so there is a lot of snowfall.
