残念。PM2.5ではありませんでした。
前の日までの気温は温か。春が近いんだなと思わしといて、
この日、寒冷前線に覆われてしまいました。この時期に何度か寒冷前線の波状攻撃がありました。
温かな大地と冷気とが遭遇するとだいたい霧が発生するものです。
ほとんどの霧は日照で暖められると消え去るものですが
この日の霧は昼過ぎでも消えず、しばらく白かった。
Oops. It's not PM2.5.
Feel warm til the day fefore.
The next day, cold front line invaded this area.
So warmed ground becomes foggy arounc.
Usually almost fog is used to clear by the sunrise,
but vast covering fog lasterd until noon.
