Generally speaking, Lanzhou is in the transition zone between monsoon climate zone and non-monsoon climate zone, which belongs to a typical temperate semi-arid continental monsoon climate with the characteristics of large temperature difference and less precipitation.
I remember my first day of college in Lanzhou. Just got off the school bus, I found my lips cracked and blood oozed. That night, we southern boys had nosebleeds. Sprinkle some water on the ground before going to bed. It took a long time to get used to this weather. Summer is coming, and we have to keep filling it like buckets. When winter comes, I usually put some lip balm and some moisturizer on my face and hands. Otherwise, your face will age a lot in the long run. Usually there is little rainfall, and it hardly rains in winter; It rains only occasionally in Mao Mao in Mao Mao.
It is not hot in summer and not cold in winter. In summer, in Lanzhou, people seldom sweat and don't feel very hot. My biggest feeling in Lanzhou is that there is no need to install fans indoors. Even when it is extremely hot outside in summer, I can't feel the heat when I walk indoors or in the shade. No matter how hot it is outside, people will feel cool as soon as they enter the room. I think it may be the latitude (I feel that is the reason, I don't know much, and I didn't learn geography well. Therefore, Lanzhou is a good place for summer vacation. Of course, the outdoor sunshine in Lanzhou is also very toxic in summer, and the ultraviolet rays are very strong. If you get too much sun, you will lose your skin. In the hottest time in Guangdong, even if I didn't walk, I was sweating all the time, and I was soaked when I went shopping outside. After a short walk, I had to rest in an air-conditioned shop. It's too hot to sleep at night. I have no appetite for anything. In winter, in Lanzhou, the weather is not too cold. You will feel cold when the wind is strong. The weather in the south is humid and it feels very cold in winter. In the words of Beijing, a thief is cold and a thief is cold, just like the feeling of soaking in ice water, which is really uncomfortable. What's more, it rains a lot in winter in the south.
The temperature difference between morning and evening in Lanzhou is generally 5- 15 degrees Celsius, especially in autumn and winter. Often one day is like three seasons. Especially in September 10, when I get up in the morning, the slight wind caresses my face, which is as cool as autumn. The sun comes out at noon, and the temperature rises a lot. It feels like summer. When I came back from self-study at night, the northwest wind blew and I couldn't help sneezing.
Friends who have lived in the south for a long time may not feel the power of this weather. When the sandstorm blows, it is cloudy all around, regardless of heaven and earth. The minimum visibility is only 100 meter. Gravel with loess keeps entering your eyes, making you unable to open them. There are fewer people outside than usual, and occasionally I see a few girls wrapped tightly marching. The worst time, my roommate met a sandstorm on his way back from bathing in the bathhouse. When I came back, I was covered in dust and covered with dust, like an Afghan refugee. We hardly recognized him. According to experts' research, there is a vivid description of sandstorms in the poem Out of the Great Wall by Wang Zhihuan, a poet in the Tang Dynasty. The first sentence of this poem: "Yellow sand is far above the white clouds, and Wan Ren Mountain is an isolated city" has been mistaken for "Yellow River" in feudal society, and the magnificent poem of sandstorm is almost buried in the dust of history. Now, the greening in Lanzhou is much better than before. Occasionally there is sand blowing, and sandstorms used to be common.
The weather in Lanzhou makes me happy and worried.
I don't know why there is always a faint sadness in my heart when it rains in the northwest.
