The weather

What is the Weather?

The weather is all the elements in the atmosphere right now

• Look out the window, how many elements can you see…

• Is it cloudy?• Is it windy- are the trees moving?• How far can you see?• Is it warm outside?• Is it dry or raining?• Is the sun shining?

Sunshine

Without the sun, nothing on planet earth would survive.

We measure the sun using a Sunshine Recorder

And we record sunshine in hours

Temperature

• Temperature is all the heat that is in the atmosphere.

• We talk about how warm or cold it is

• We use a thermometer and measure temperature in °C

Precipitation

• All the moisture in the air.

• Rain• Sleet • Snow• Drizzle• Hail

We measure it using a rain gauge in mm

Wind

• Wind is the movement of the air.

• We will be studying wind speed and wind direction.

Cloud Cover and Visibility

• We like to record the amount of clouds in the sky, in oktas.

• Visibility is how far you can see and is measured in meters.

• We record both with our eyes.

Air Pressure

• Air pressure is the weight of the air.

• The air is as heavy as a Mini Adventure on top of your head.

• We record air pressure with a barograph or barometer.

• We measure air pressure in milibars (mb)
