What effect does cloudy weather have on life?

Cloudy clouds only blocked some light and weakened photosynthesis, but they didn't stop. It depends on when it is hot in summer. Cloudy weather can also reduce solar radiation and give people shade. If it is winter, it will affect the temperature rise and reduce the warm sun and warmth.

Cloudiness will weaken the photosynthesis of plants, but it will not stop. In winter in southwest China, the sun is often not seen for ten and a half months, and crops are growing, but poor light and heat conditions will affect the harvest. When it is cloudy, it can also heat up during the day, and the penetration of visible light and heat. The demand of crops for light and heat is not as much as possible.

Plant growth needs photosynthesis, so it needs proper illumination. If the clouds are too thick or there is fog, rain and snow, it will temporarily affect the lighting.

Cloudiness refers to the thick clouds in the sky, which have certain reflection on solar radiation, but it cannot be said that it is completely isolated from solar radiation. Water vapor and carbon dioxide in the air will absorb some solar radiation and some will be absorbed by the earth. On cloudy days, the atmospheric inverse radiation is strong, so the temperature difference will be smaller.

Therefore, even on cloudy days, the temperature in the air is not necessarily low, and it may even feel hotter than when the sun shines.

For us, cloudy weather has no effect on life, just live a normal life, pay attention to safety and sun protection.
