Why does it rain and thunder at night?

When the temperature drops at night, the water evaporated during the day forms small drops at high altitude and low temperature, that is, the water changes from vaporized state to liquid state, which can only be carried out at low temperature and is an exothermic process; These small water droplets gradually accumulated, forming a precursor to the arrival of thunderstorm weather-Lei Yun.

This is why thunder and rain often happen at night. In a word, it is colder at night than during the day, which is the fundamental reason.

I hope the answer will help you.
