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.
