Meteorological definition of a meteor – according to the World Meteorological Organization (WMO)
In meteorology, a phenomenon observed in the atmosphere or on the surface of the Earth is known as a meteor.
在氣象學中，在大氣層或地球表面觀測到的現象稱為大氣現象。
It may be a form of precipitation, a suspension or a deposit of liquid or solid particles. It may also be a form of optical or electrical phenomena. Meteors are generally visible to human observers, but in the case of thunder, it is audible.
它可以是沉澱物、懸浮液或液體或固體顆粒的沉積物等形式。它也可以是光學或電學現象的形式。人類觀測人員通常可以看到大氣現象，但是有雷聲的情況下，它是可聽見的。
Sometimes, names of meteors are also applied to related concepts. For instance, the word “snow” may refer to a type of hydrometeor (ensemble of falling particles), to snow cover (ensemble of particles lying on the ground) or to the substance snow (as in “snow blown from mountains” or a snowball). The constituent particles of snow in these three cases are either snow crystals or snowflakes.
有時，大氣現象的名稱也適用於相關概念。 例如，「雪」這個字可能指的是一種水凝物（落下的顆粒的集合）、積雪（地面上顆粒的集合）或物質性的雪（如「從山上吹來的雪」或雪球）。 在這三種情況下，雪的組成顆粒是雪晶或雪花。
Also, certain meteors are named based on their constituent particles; for example, the hydrometeor “snow grains” is an ensemble of falling snow grains.
此外，某些大氣現像是根據其組成粒子而命名的；例如，水凝物「米雪」是下降雪粒的集合體。
