Why do blue sky and white clouds often only appear in high temperature days?

Is this related to the weather and climate? Classification error, how to get to the computer/network in the operating system/system failure part.

Simply put, the blue sky and white clouds have nothing to do with heat or not, but only with the quantity and visibility of visible suspended particles in the air.

If the air is clean and pollution-free, as long as it is sunny and cloudy, it should be blue sky and white clouds.

When the air pollution is serious, the weather with blue sky and white clouds will generally only appear after rain or windy weather clears up, because there are fewer suspended particles visible in the air at this time, and the visibility of the air is higher.

Good luck! If you have any questions, ask them. This is helpful and I hope to adopt them.
