What do you mean by warm and sunny spring and cold and rainy spring?

The phrase "bloom is warm in spring, and it is chilly in spring" means that the weather turns warmer in spring, and it is sunny most of the time, but sometimes it rains.

This proverb describes the climate characteristics of spring. Spring is the season when the temperature rises gradually and everything recovers. Usually, the weather in spring is changeable, sometimes it rains and sometimes it is sunny.

In spring, warm air is gradually strengthened and cold air is gradually weakened, so the weather in spring is usually warmer and sunny. But when the cold air goes south again, it will form convection with the warm air, causing rainfall. Therefore, it will rain in spring.

Generally speaking, the proverb "bloom is warm in spring and chilly in spring" means that although the weather in spring is warm and sunny most of the time, it sometimes rains, reminding people to change clothes in time according to the weather changes and pay attention to keep warm.
