Severe weather affects everyone on our planet. Events impact individuals, economies, governments, wars - in fact, the course of history itself. This website will take you through a journey of severe weather with links to:

• current and forecast weather and archived weather events and data,
• more than sixty examples of case studies,
• numerical simulations of virtually all types of severe weather events.

We provide links to photo galleries, animations, and interactive applets topics ranging from introductory meteorology to specifics of particular severe weather phenomenon.

The content of this website and the accompanying textbook Severe and Hazardous Weather: An Introduction to High Impact Meteorology is the result of the authors teaching over 17,000 students at the University of Illinois since 1984.

We invite you to explore severe weather in the pages provided here. Immerse yourself in the wonder and amazement of the power of weather!
