Wind creation
- Wind creation
Wind is created when it is cold in one area and warm in another. The greater the temperature difference, the stronger the wind.
In contrast to solar energy, wind energy is not very uniformly distributed. Coastal areas or mountain peaks have significantly more wind than inland areas. The wind force also varies according to air currents, natural obstacles and geographical location.
- Experiment: circulation – in what direction does the wind flow?
You need the following:
– thermometer (2x multimeter: PeakTech 4380)
– (candle) holder
– tea lights
– log sheet to record the experiment

Idea behind the experiment:
As already mentioned above, wind is created because of a temperature difference. With this experiment we want to determine the circulation of the wind based on temperatures recorded in the hallway and in the classroom. The direction of the candle flames allows us to identify the direction of the wind.
Note:
Compare the temperatures inside the classroom and the hallway. What do you notice?
Record the direction of the candle flames on the log sheet.

How is wind created?
Wind is created when it is cold in one area and warm in another. The greater the temperature difference, the stronger the wind.
This is easily observed on the coast. During the day, the sun heats the land more quickly than the water, which leads to a difference in temperature. As you can see on the drawing, this is why the wind flows inwards in the direction of the coast and the land. At night, the direction of the wind changes. Since the land cools more quickly, it is now warmer above the water surface.
