The difference between sunny and cloudy days.

Different weather conditions, sunlight exposure range, etc.

1. Weather conditions: A sunny day means that there are almost no clouds in the sky, or there are few clouds and the sun is shining. In meteorology, sunny days usually mean that the amount of clouds in the sky is less than 30% (30%). This kind of weather usually gives people the impression that the sky is clear and sunny. Cloudy refers to a certain amount of clouds in the sky, sometimes thin and sometimes dense. In meteorology, cloudy usually means that there are 4-70% medium-low clouds or 6- 10% high clouds in the sky. This kind of weather may give people the impression that the sky is a little gloomy, and the sun shines through the clouds, making the scenery a little blurred.

2. Sunlight irradiation range: On sunny days, the sun can completely irradiate the ground, making the sky bright and the temperature high. On cloudy days, the sun is partially or completely blocked by clouds, which makes the sky look gloomy and the temperature is relatively low.
