Under what circumstances will there be misty rain?

Misty rain is like drizzle: when Wushan is gray, green apes crow the highest branches.

Rain and rain are water drops falling from the clouds. Water on land and sea surface evaporates into steam. Steam rises to a certain height and turns into water droplets when it is cold. These small water droplets form clouds. They collide with each other in the cloud and merge into large water droplets. When it is too big for the air, it will fall from the clouds and form rain. There are many reasons for the rain, and the manifestations are unique, including Mao Mao rain, continuous rain and pouring rain.

Fog If the air near the ground is cooled to a certain extent under the condition of sufficient water vapor, breeze and stable atmosphere, the water vapor in the air will condense into tiny water droplets and be suspended in the air, which will reduce the visibility of the ground. This weather phenomenon is called fog. Fog is more common in spring from February to April. When the visibility in the atmosphere is lower than 1 km due to the condensation of suspended water vapor, meteorology calls this weather phenomenon fog. Conditions for fog formation: cooling, humidifying and increasing water vapor content.

Weather between rain and fog can be called misty rain.

I wonder if my answer can satisfy you. If so, please adopt it in time.
