Last week, Monet finally made her debut as a live newscaster. One scene that stood out was the one in which Monet's father repeatedly played a recording of him saying, "Is winter approaching in Tokyo?"

There is a wind called "Kogarashi No. 1" that blows as a symbol of the arrival of winter, and today we will be asking a quiz about it.
Which of the following is correct about the first cold wind of the year announced by the Japan Meteorological Agency? Difficulty level is ★★★☆☆(1/3)!

• 
  Announced throughout Japan
  Incorrect
• 
  Published annually
  Incorrect
• 
  It is a northerly wind
  Correct answer

  The strong northerly winds that blow from late autumn to early winter are called kogashi, and the first kogashi of the year is called "kogashi no. 1." The Japan Meteorological Agency defines a kogashi as a time when, during a certain period of time, a northerly wind with a maximum wind speed of 8 meters or more blows in a winter-type atmospheric pressure pattern with high pressure in the west and low pressure in the east.

  This Kogarashi No. 1 is actuallyOnly in Tokyo and the Kinki regionIt will be announced. AndAt a certain timeThis is different between Tokyo and the Kinki region.

  Tokyo: Mid-October to late November
  Kinki: Frost (around October 10rd) to winter solstice (December 23st)

  Because the announcement period is set like this, if no winds that meet the conditions blow within that period, it will be treated as "no announcement." In fact, Kogarashi No. 2018 was not announced in Tokyo in 2019 and 1, and 2020 was the first time it was announced in three years.

  In 2020, the first storm of kogarashi was announced in Tokyo on November 11th. Below is the weather chart from that time.

  
  There is high pressure to the west of Japan and low pressure to the east, creating a winter-like pressure pattern of "high pressure in the west, low pressure in the east," which we can see meets one of the conditions for the first Kogarashi wind.

I've loved the weather since I was in elementary school, and I qualified as a weather forecaster when I was in the third year of junior high school! I'm currently a third-year university student, and I teach elementary school students how interesting the weather is, and I also work as a guide at the Japan Meteorological Agency's Meteorological Science Museum. I want as many people as possible to enrich their lives by learning about the weather, so I work with the weather every day.
