Sunny day, rainstorm, cold and frost, which one can't describe the weather?

Frost is not.

A sunny day means that there are no or few clouds in the sky.

Heavy rain refers to heavy and urgent rain.

Cold means low temperature.

Frost is a common agrometeorological disaster, which means that the temperature drops suddenly and the surface temperature drops below 0℃, causing damage to crops and even death. Frost usually appears in autumn, winter and spring. It is different from frost. "Frost" is a white ice crystal that condenses directly on objects when the water vapor in the air near the ground reaches saturation and the ground temperature is lower than 0℃. When there is frost, it is not necessarily frost.
