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
