IPA: /ˌhaɪdrəˈmɪtər/
KK: /haɪdroʊˈmiːtəˌr/
A type of weather phenomenon that includes forms of precipitation like rain, snow, fog, or clouds, created when water vapor in the air condenses.
The hydrometeor fell gently from the sky, covering the ground in a soft layer of snow.
Hydrometeor is formed from "hydro-" (from Greek "hydor", meaning water) and "meteor" (from Greek "meteōron", meaning something high in the air or atmospheric phenomenon). The word refers to atmospheric phenomena that involve water, such as rain or snow.
Think of 'water' ('hydro-') and 'atmospheric phenomena' ('meteor') to remember that a hydrometeor is related to weather events involving water.
