Cyclone Families - Cyclogenesis Regions

  • Many cyclones in different phases of their evolution are often observed along the polar front
  • Cyclogenesis over the US tends to occur near:
    • Eastern Slope of the Rockies
    • The Great Basin Area
    • Gulf of Mexico
    • Atlantic Coast east of the Carolinas
    • Gulf of Alaska
  • Sometimes, cyclones deepen very rapidly - if deepening rate exceeds 24 mb in 24 hours, it is referred to as explosive cyclogenesis and the associated storm is often called a "bomb"
  • Explosive cyclogenesis often occurs during the winter months just off the east coast of the US
