What are the factors that affect sunshine hours?

There are four main factors affecting sunshine time: sunshine length, topography, weather conditions and latitude.

Day length: the longer the daytime, the longer the sunshine time, and vice versa;

Terrain: high terrain, early sunrise, late sunset and long sunshine time;

Weather conditions: sunny weather, warm temperature and relatively long sunshine time, and vice versa;

Latitude: The lower the latitude, the longer the sunshine time, and the higher the latitude, the shorter the sunshine time.

The country with the longest sunshine time in the world: the Sahara desert in northern Africa. The average annual sunshine duration is as long as 4,300 hours, which means that you can see dazzling sunshine for an average of 1 1 hour for 45 minutes every day.
