Mr. Samejima, you ran under the standard time! It turns out that wind can affect sports performance!

This time, it's a quiz about "wind"! Difficulty level: ★★★☆☆(3/5)!
When a typhoon approaches, you may hear the term "storm zone." A storm zone is an area where "the average wind speed of 25 m/s or more is blowing due to the typhoon" or "where it is likely to blow if there are no influences from the terrain." So, which of the following options is this "25 m/s" speed?

• 
  People's walking speed
  Incorrect
• 
  The speed at which the train runs
  Correct answer

  Another way to say a wind speed of 25m/s is that the wind moves at a speed of 1m per second. This can be converted to 25km/h, or 90km per hour, which is roughly the speed at which a train travels!

  

  The photo shows the strength of the wind! You can see that even strong winds with an average wind speed of 15m/s or more can be quite dangerous!

  In addition to the familiar unit of m/s, the unit of wind is kt (knots), which indicates how many nautical miles (1 nautical mile is 1 km) you can move in one hour!

  From now on, typhoons are more likely to approach. Be aware of the wind and take adequate precautions!

My favorite sky is the sky at dusk. I don't think there's anything that can beat that gradation (laughs). Since I was a child, I've been interested in the weather, which changes every day, and last fall I obtained a weather forecaster license. I would be happy if many people could learn about the depth of the weather!
