Understanding extreme weather terms from bomb cyclone to atmospheric river

thestar.com

Recent years have seen an increase in the use of specific weather terms. The American Meteorological Society defines several key terms related to extreme weather events. A bomb cyclone is a storm outside the tropics characterized by a rapid drop in central pressure. This phenomenon, known as bombogenesis, often occurs in cold seasons and can exhibit hurricane-like features. An atmospheric river is a narrow corridor of water vapor linked to heavy rainfall. A heat dome traps warm air under high pressure, leading to stagnant conditions. The polar vortex refers to the circulation of air around the poles, influencing cold air outbreaks.
