METEOROLOGY TODAY, Ninth Edition, is one of the most widely used and authoritative texts for the introductory
meteorology course. C. Donald Ahrens teaches students to observe the weather actively so they can apply the text
material to the world around them. This ninth edition helps students understand and appreciate the dynamic nature
of the inevitable weather phenomena that continually influence our lives. The text's clear and inviting narrative
is supplemented by numerous pedagogical features that encourage observing, calculating, and synthesizing information.
