今日のモールス電文・・・樹氷
frost-covered trees appear when water droplets
or snow in the air are blown by the wind and freeze on trees .
a famous place to see this is the zao mountain range,
which crosses the borders of yamagata and miyagi prefecture.
樹氷は空気中の水滴や雪が風で樹木に吹き付けられ、凍って出来ます。
山形、宮城、県境の蔵王連峰で見られるものが有名です。
