More about hyetal
The English adjective hyetal is very uncommon, used only in meteorology. The Greek noun 丑测别迟蠈蝉 means 鈥渞ain鈥�; the noun 丑测别迟铆补 means 鈥渞ainy weather鈥�; both nouns derive from the verb 丑媒别颈苍 鈥渢o rain.鈥� In English and other languages (German, for example), verbs of weather and natural phenomena are impersonal (e.g., it is raining, es regnet; it is snowing, es schneit). In Greek, however, such verbs are personal, Zeus or another god being understood as the subject if not explicitly named; thus 丑媒别颈 means to a Greek not 鈥渋t is raining,鈥� but 鈥淶eus is raining,鈥� and 苍别铆辫丑别颈 鈥淶eus is snowing.鈥� Hyetal entered English in the 19th century.
