What is the difference and connection between weather and climate?

Both weather and climate are used to describe the movement of the atmosphere, but weather refers to the movement of the atmosphere in a short time in a certain area, while climate refers to the synthesis of weather conditions that have occurred frequently in a certain area for many years. For example, from mid-June to mid-July every year, rainy, muggy and humid plum rains often appear in the middle and lower reaches of the Yangtze River, which is the local climate characteristic. The short time in the weather can be one day, several days, January, one year or several years. We can say that the weather is good today, this month, this year and these years, but we can't say that it is good today and this year. Climate is the weather feature of a place for decades, hundreds of years or even longer.
