Meteorologiska symboler
Meteorologiska symboler (även vädersymboler) är symboler som används på väderkartor för att markera observationer eller beskriva prognoser.
Väder
Nedan till vänsterlistas de vanligaste vädersymbolerna som syns på västerländska väderkartor, och nedan till höger syns symbolerna som används på väderkartorna i Östasien.
Symbolerna varierar dock något i utseende och betydelse mellan olika länder och väderlekstjänster. Exempelvis använder svenska SMHI 27 olika vädersymboler på sina kartor (2023),[1] medan exempelvis Klart.se har sina symboler och förklaringar.[2]
