About the Product

Meteorology Today 1st Canadian edition is the first textbook of its type written specifically with the needs of the Canadian market and its unique meteorological environment in mind. This first Canadian edition builds upon the tried and tested strengths of the Ahrens Meteorology series and provides a more relevant resource for Canadian students and instructors by ensuring that Canadian content, practices, conventions and examples are used throughout. An Earth Systems feature – the first of its kind in Ahrens – has been developed for this edition, presenting the interconnectedness of elements, and providing a peek at the chapter content. This “visual table of contents” highlights the Earth system components reflected in each chapter (the atmosphere; hydrosphere, cryosphere, lithosphere, biosphere and anthrosphere). The relationships between the chapter’s content and Earth systems are further expanded upon in the introduction of each chapter.


  • Canadian Air Mass/Front model, and descriptions of the Canadian forecast system

  • North American weather and climate maps

  • Canadian weather facts, major weather events, and records set in a global context

  • Special topics like: How do weather broadcasters do it?, Why are Canada’s coastal regions so foggy? and Measuring snow depth, are covered in many new Focus on a… boxes with expert guest writers like Claire Martin from CBC News.

  • Tephigrams used to assess stability are explained

  • Inclusion of Canadian examples from coast-coast-coast such as:

  • Marine influences/climates

  • BC’s temperate rainforest

  • Alberta’s Chinook

  • Prairies as a breeding ground for thunderstorms

  • Summer heat in southern Ontario and eastern Quebec

  • Delayed spring in the Maritimes due to thermal lag

  • Hurricanes that have impacted Canada

  • Canadian practices and Canadian examples such as Arctic observations, recent work on regional-scale weather forecasting and weather and climate change research

  • Additional resources can be found at This companion website includes a password-protected Instructor’s Resource section which includes the ancillaries listed above, as well as a Student Resources section with additional self-testing review quizzes and Active Figures.

About the Author

C. Donald Ahrens

In 2007, the National Weather Association awarded him a lifetime achievement award for these accomplishments. The bestselling author of two Cengage texts, Professor Ahrens received the Textbook and Academic Authors Association's McGuffey Longevity Award for the 9th Edition of his market-leading METEOROLOGY TODAY.

Peter L. Jackson

Peter L. Jackson is Professor of Atmospheric Science in the Environmental Science & Engineering Programs in the Natural Resources and Environmental Studies Institute at the University of Northern British Columbia. Professor Jackson is both an academic and a trained meteorologist whose research mostly concerns windflow in complex terrain (i.e. in mountains and along coastlines) and environmental applications.

Chris Jackson

Christine Jackson is a senior laboratory instructor in the Geography Program at the University of Northern British Columbia with degrees in Physical Geography and Education. She develops, coordinates and teaches experiential labs in courses on weather and climate, geomorphology, and soils. Prior to joining UNBC she taught climatology and geomorphology at the College of New Caledonia, preceded by several years working in museum education, science and technology community development, as an educator in the school system, and as a lab demonstrator and coordinator at the University of British Columbia. She is interested in improving understanding of the natural environment through applied learning and gives workshops to train educators to do this in the school system.
