Please explain the reasons for the dry climate in northwest China (Gansu, Xinjiang, Ningxia, Shaanxi, etc.). ). Details are in the supplement.

First, let me introduce myself. I come from Gansu, and my parents are authentic farmers. Now I am studying in Liaoning. First of all, the northwest is a typical temperate continental climate. Winter is cold and dry, and summer is hot and rainy. Crops generally mature before August, and only potatoes will be a little late. There is little rainfall in July. In some years, there is little rain in a month, and August and September belong to autumn. But there is a lot of rain in our normal autumn harvest year, which will affect the autumn harvest almost every year! As a farmer's child, I hate this climate of little rain in summer and rainy in autumn. 5438+ 10 The rainfall in June is moderate, but it may rain sleet later!

The second question, drying clothes, may only be three or four hours a day in summer, but it is not easy to dry for two or three days in winter!

The third question, roses, we also have roses at home. You must find a particularly good weather to dry the roses in one day.

The fourth question, the local crop planting structure, Gansu mainly grows wheat, corn and potatoes, but Tianshui, the southernmost part of Gansu, will be more mature because of the subtropical monsoon climate.

The fifth question is more specific. . . Take our family as an example. Our home is located in Hexi Corridor in central Gansu Province. Specifically, crops in Jiaojiazhuang Village, Jiaojiazhuang Township, Yongchang County, Jinchang mainly grow wheat and barley. In recent years, barley prices have soared. We all grow barley there, and the yield of barley is higher than that of wheat. Farmers' income will be higher. It is usually harvested in August around Tomb-Sweeping Day.

This is the place where I was born and raised, in the northwest corner. Haha, laugh at yourself. The climate is really not so good. Compared with Liaoning, it is too dry. The main reason is that there are too few plants on the surface and too much sand, and the temperature difference between day and night is too big (wearing cotton-padded jacket in the morning and wearing yarn in the afternoon, eating watermelon around the stove). I hope I can help you.
