What's the weather like with lightning on the clouds?

There is a flash of lightning on the cloud, which means there is a thunderstorm.

Weather refers to the specific state of the near-surface atmosphere in a certain area in a short time, and wind is caused by uneven distribution of air pressure in the horizontal direction. Clouds are formed by many tiny water droplets or ice crystals. The reason of fog formation is that warm and humid air moves horizontally, passes through the cold ground or water surface, and gradually cools to form fog; It rains because clouds collide with each other in the clouds and merge into large water droplets. When it is too big for the air, it will fall from the clouds and form rain. Snow is because there must be condensation nuclei in the water; However, frost is always formed under weather conditions that are conducive to radiation cooling on the surface of objects.
