Warm Snow Day
Today the snow piled up high after a long interval.
暖かい雪の日
It was scared for me to drive a snowy road as ever.
今日は久しぶりに雪が積もりました。
However, since I felt that it was warmer than usual, I searched for the reason.
雪道を運転するのは相変わらず怖かったです。
When the snow falls, the height of cloud become low, and radiative cooling is suppressed.
しかしいつもよりも暖かく感じましたので、その理由を調べてみました。
Also, when the snow is piled up, the effect of solar radiation reflected from snow surfaces becomes large, and it could make us feel warm.
雪が降ると雲の位置が低く、放射冷却が起こりにくくなります。
Furthermore, if a condition that wind is calm is added, we seem to feel the snow day as a warm day.
また、雪が積もっていると雪面反射の影響が大きく、暖かく感じるそうです。
