The weatherman uses different words to describe how sunny or how cloudy they think it will be.To choose which word to tell us, they first measure how much the clouds the sky.They look up at the sky they can see, and pretend to divide the sky in 8 equal parts, They call each part an okta.Then they notice all the clouds in the sky above them, but not the clouds that are see-through where you can see the sky behind it, they don’t count those. Then they think if we put all the clouds beside each other, how many okta’s would the clouds cover. The number they come up with will help them know which words they will use to describe the sky to us.If there are no clouds in the sky, the Meteorologist will say it’s Sunny.If there are 1 to 2 okta’s of clouds covering an area, then the weather man will say it’s mostly sunnyThe Meteorologist might say it’s partly sunny or partly clouds if there are 3,4 or 5 okta’s of clouds covering an area.If there are 6 or 7 okta’s of clouds covering an area that is called mostly cloudy.
