The daily temperature difference on cloudy days is smaller than that on sunny days. Why?

Hello. The main feature of cloudy weather is deep clouds. During the day, clouds consume some heat by weakening solar radiation (in the form of absorption, reflection and scattering), so that the temperature during the day is not too high; At night, the clouds reflect most of the ground radiation back to the ground through heat preservation, so that the temperature at night is not too low. The temperature will not be too high during the day and too low at night, so the daily temperature change range is relatively small.

I hope it helps you. Thank you.
