As you can see, it's raining. I'm here to measure the rain! We do this using a rain gauge. We collect the rain, or precipitation, in the rain gauge, which is a container with a scale marked on it. We can then measure the amount of rain in the rain guage.
It's very windy!
To measure the speed of the wind, we use an anemometer. It has a set of little cups which the wind turns, and a dial shows us the speed of the wind. If we want to measure the direction the wind is blowing from, we use a wind vane or a wind sock. You might have seen wind vanes on top of farmhouses, and wind socks on the runway at airports.
Finally, cloud cover!
When we look up at the sky, we imagine splitting the sky up into eighths. Each of these eighths is called an okta. For example, if we think half of the sky is covered with cloud, we would record 4 oktas. And if we thought 3/4 of the sky was covered, we would record 6 oktas. Easy!
