Is it normal to snow in Gannan in June this year? Is it like this every year? Is there a big temperature difference between morning and evening?

Xinhuanet Lanzhou, June 19 (Reporter Wei) The reporter learned from Lanzhou Central Meteorological Observatory that there was moderate to heavy rain in Gannan Tibetan Autonomous Prefecture of Gansu Province from 8: 00 on June 18 to the early morning of June 19, and the minimum temperature dropped to above 0℃ and below 1℃. At 5 o'clock on June 19, Gannan Prefecture cooperated.

Because snowfall is wet snow with high water content, the snow covers the green grass all over the mountain, the highland barley in the field and the trees on the roadside, and the branches and leaves of poplar trees on both sides of the road are crushed and lying on the roadside in disorder. Pedestrians and vehicles on the road are very cautious, and many people wear warm clothes only in winter.

According to the staff of the forecast department of Gannan Meteorological Observatory, the snowfall in mid-June is rare in the history of meteorological observation in Gannan. Take the cooperative city as an example. In the past 30 years, the climate probability of snowfall in the cooperative city in mid-June is only 0.3%. In addition, the snowfall with a snow depth of about 3 cm may cause local crops such as spring wheat and highland barley to suffer from low temperature freezing or lodging.

(Plateau, the temperature difference between morning and evening is definitely large)
