Sirocco – a hot wind that begins in the Sahara and moves across the Mediterranean, often bringing dust

Southwester – a strong wind or storm that is moving in a south-west direction

Trade wind – a wind that blows continuously towards the equator (=the imaginary line around the middle of the Earth)

Turbulence – sudden violent movements of air or water

Twister – a tornado

Typhoon – a tropical storm with strong winds that move in circles

Whirlwind – a very powerful dangerous wind that spins extremely fast, carrying away anything in its path

Wind – a natural current of air that moves fast enough for you to feel it Windstorm – a period of bad weather when there is a lot of wind but no rain Zephyr – a gentle wind

Wind is the effect of the sun heating our planet. When the sun sets, the wind usually reduces in speed. The wind can tell us a lot about what is happening and what is about to happen.

When the wind is calm, under 10 miles per hour, it is telling us that there is going to be little or no change in the weather we are currently having.

When the wind picks up in speed it indicates the weather is going to change.

You cannot rely on just the wind to make this determination but it is a good sign that when the wind is picking up, things will be changing.
