energy transferring into the water vapor and out of the air parcel.

energy transferring out of the water vapor in the air parcel.

the air in the air parcel cooling and condensing into liquid water, then falling as rain.

the air in the air parcel at equilibrium and transferring energy out of the cloud as rain.

the air in the air parcel heating up and condensing into liquid water, then falling as rain.

Out of the air parcel

Into the air parcel

Air Parcel 1

Air Parcel 2

Air Parcel 2 will lose energy to the surrounding air, which will cause more water vapor to fall as rain.

Both air parcels will have the same amount of rain. They have the same surrounding air temperature, so the same amount of water vapor will fall as rain.

Air Parcel 2 will gain energy from the surrounding air, which will cause more water vapor to fall as rain.

Air Parcel 1 is colder than Air Parcel 2, so more water vapor will fall as rain.

"These are just a few of the factors that can keep the water droplets in clouds from turning into precipitation that falls to the ground."

"Thin, wispy clouds are usually made up of tiny ice crystals, and the ice crystals are spread too far apart to collide and form snowflakes."

"...if there aren't enough droplets of water in a cloud to collide and form large drops, the tiny droplets will stay suspended in the air and it won't rain."

"Clouds produce rain when tiny droplets of liquid water begin to stick together, forming larger and larger drops."
