There were a lot of exciting scenes last week! During that time, there was a scene on J-Tele where Monet was studying a page about "South Coast Low Pressure Systems." Did you notice?

"South coast low pressure" is what brings heavy snow to the Pacific coast. So this time, we have prepared a question about "snow". Although it is still hot, I want you to think about it while remembering the cold of winter!

Which of the following is most likely to snow? Difficulty rating: ★★★☆☆(3/5).

• 
  High temperatures and high humidity
  Incorrect
• 
  Low temperature and high humidity
  Incorrect
• 
  Low temperature and low humidity
  Correct answer

  It's easy to imagine that low temperatures make it more likely to snow, but humidity is also a factor in determining whether it will snow or rain. When humidity is low (= dry), snow can turn into water vapor on its surface, and as this happens it takes away heat, making it more likely to fall to the ground as snow.

I'm a fourth-year university student in Yokohama. I commute to school by bicycle and find it soothing to watch the different weather patterns every day. I'm studying a field other than meteorology at university, but by encountering meteorology I've had many new encounters. I hope you'll all enjoy the fascinating world of meteorology through "Okaeri Mone"!
