A little exercise about weather change

Not long ago, the sun shone violently on us. It's so hot that I can hardly breathe. But these days, it suddenly became so cold. Why? I'm really curious.

This morning, my father bought a newspaper and put it on the table when he came back from shopping. After breakfast, I flipped through the newspaper and came across the reason for the weather change. It turns out that in a year, there are two major weather systems that will affect us: one is the cold air from the north, and the other is the subtropical high in the south. Winter is controlled by cold air, and it is often sunny and hot when it is controlled by subtropical high.

The continuous high temperature days in the past few days were caused by the subtropical high firmly controlling the Jiangnan area. However, the two weather systems are not so clearly divided. In winter, the subtropical high sometimes indirectly affects us. On the contrary, in summer, small weak cold air will occasionally come over.

So I think it will never be cold in winter from beginning to end, and occasionally it will be cold for a few days in summer. I finally know how changeable the weather is. I like our earth and its wonderful changes. . . . . .
