Weather Science : Pierrot And Rain And Snow (1979)

[Music] ooh look at all the clouds Celestine do you see the pictures the clouds are making mm Wanita uh-uh I see [Music] something it's a [Music] cat [Music] I don't see a cat where there no it's all gone now but look look there's the professor the professor where where uh I don't know where did he [Music] go now that's a question mark isn't it a question mark Pio where do you see a question mark [Music] uh I've got a question how come you're seeing all these things in the cloud [Laughter] yeah sure go ahead and laugh all I know is I saw what I saw how come clouds can do that how come they can change their shapes like that what are the clouds made out of anyhow I'll go ask the professor professor professor who's there it's me Pio Professor could you tell me about clouds clouds clouds clouds cause me nothing but trouble look how they get in front of my telescope I can't look at important things in the sky when they're around clouds but Professor could you please tell me what clouds are made out of oh certainly clouds are made of tiny drops of water would you like to see how the water gets into the air and forms clouds H good now you know that most of the Earth is covered with water the oceans that's right water from the oceans is always evaporating tiny bits of it are always Rising into the air when the sun warms the air the air rises and carries the water up with it higher and higher into the sky hey we're going up too just like the water in the air yes now as the air goes up it gets cooler cool air can't hold as much water as warm air can so the tiny bits of water come out of the air and get bigger they condense they become tiny water drops that stick together and form a cloud I feel the water I'm getting wet and and the air it's cold but the droplets in the cloud are getting bigger and bigger heavier and heavier when they're too heavy to float in the air they fall out of the cloud and down to the Earth that's called rain so that's how we get [Music] rain Professor the wind I know it's getting stronger we better go back down that was fun yes it was now if you use your imagination a little bit more we'll see where snow comes from but we'll have to pretend that it's winter and the temperature where the clouds are is below freezing o o okay Professor it's winter when it's cold clouds aren't made of water droplets instead they're made of ice cryst CST now look each snowflake was formed in a cloud tiny crystals of ice got bigger and bigger until they were too heavy to float in the air then they fell to Earth as snowflakes snowflakes are crystals of ice that have six sides they're shaped like hexagons and everyone is different no two are ever exactly alike so rain and snow both come from clouds when it's warm we get rain and when it's cold enough we get snow that's right po can we stop pretending it's winter are you getting too cold yes I am I think we've used our imaginations quite enough for one day per it's much more pleasant being warm and enjoying the sunshine there that's much better thank you Professor anytime well back to work goodbye Professor goodbye I know what I'll do what thereo my goodness what are you doing up there I'm going to tell my friend booty to all about clouds and rain and [Music] snow [Music] w
