Which of the following are topics about climate? They are talking about the weather. 1. It rains at home in Huangmei season, and frogs are everywhere in the grass pond. 2. It rains a lot in Qingming Festival, and pedestrians on the road want to die. 1. The rainy season in the south of the Yangtze River is "Huangmei season", which means that plums in the south of the Yangtze River are yellow in early summer. So it rains at home in Huangmei season, and frogs are everywhere in the grass pond-the climate.

2. Tomb-Sweeping Day is one of the major festivals in Tang Dynasty. On this day, there are various activities, such as family reunion, grave sweeping or outing. But in Tomb-Sweeping Day, Chizhou, where Du Mu lives, there is no sunshine, only continuous drizzle. So it rained in succession during the Qingming Festival, and pedestrians on the road wanted to die-it was the weather.

3. It rains in the autumn pool at night-it rains heavily in Bashan tonight, and the pool is full of autumn rain. So it's the weather

4. In the season when plums are ripe, it rains continuously-the key word is season, so it is climate.

There is no cold and heat in the four seasons, and it becomes autumn when it rains-it is not hot in summer and not cold in winter all the year round, and it is a bit like autumn (a little cold) when it rains. This is the climate.

One way to judge the weather and climate is the length of time: the weather time is short and the climate time is long.
