MidLatitude Atmospheric Dynamics: A First CourseISBN: 9780470864647
336 pages
June 2006

The first five chapters constitute a companion text to introductory courses covering the dynamics of the midlatitude atmosphere. The final four chapters constitute a more advanced course, and provide insights into the diagnostic power of the quasigeostrophic approximation of the equations outlined in the previous chapters, the mesoscale dynamics of thefrontal zone, the alternative PV perspective for cyclone interpretation, and the dynamics of the lifecycle of midlatitude cyclones.
 Written in a clear and accessible style
 Features real weather examples and global case studies
 Each chapter sets out clear learning objectives and tests students’ knowledge with concluding questions and answers
A Solutions Manual is also available for this textbook on the Instructor Companion Site www.wileyeurope.com/college/martin.
“…a studentfriendly yet rigorous textbook that accomplishes what no other textbook has done before… I highly recommend this textbook. For instructors, this is a great book if they don’t have their own class notes – one can teach straight from the book. And for students, this is a great book if they don’t take good class notes – one can learn straight from the book. This is a rare attribute of advanced textbooks.”
