Put another way, this marks just the second time in history that forecasters have had to resort to the Greek alphabet because available storm names have been exhausted.

换句话说，这是历史上第二次天气预报员不得不使用希腊字母，因为可用的风暴名称已经用完了。

The World Meteorological Organization has a list of 21 potential storm names, listed alphabetically from A to W (there are no Q, U, X, Y or Z names because of availability).

Storms that are particularly deadly or costly often have their storm names retired by the WMO so they're never used again.

特别致命或代价高昂的风暴通常会被世界气象组织取消其风暴名称，因此它们再也不会被使用。

The rotating list of storm names is reused every six years. But this week, the WMO said that would not be the case with Greek-letter storms, because of their relative rarity.

风暴名称的循环列表每六年重复使用一次。但本周，世界气象组织表示，以希腊字母命名的风暴不会出现这种情况，因为它们相对罕见。
