Around today's noon, a lot of large hailstones fell in Hachioji city, Tokyo.

I was astonished because loud noises suddenly generated from outside windows.

The reason seems that cumulonimbus clouds developed rapidly due to the passing of pressure trough accompanied by cold air.

Surprisingly, the diameter of the hailstones was more than 1 cm.

In Japan, hailstones are called hyō (ひょう) when the diameter exceeds 5 mm, whereas they are called arare (あられ) when the diameter is less than 5 mm.

Incidentally, hyō and arare often fall in early summer and early winter, respectively.




驚くことに、氷粒の直径は 1 cm を超えていました。

日本では、氷粒の直径が 5 mm を超えると「ひょう」、5 mm 未満の場合は「あられ」と言います。
