COURSE OBJECTIVES

Met 600 is the first part of a two-semester course series on Advanced Atmospheric Dynamics. It is one of the core courses for the Graduate Program at the Department of Meteorology, University of Hawaii at Manoa. The objectives of MET 600 (and MET 601) are to provide an introduction to basic theories of Dynamic Meteorology and to develop students' ability to understand physically and to analyze quantitatively atmospheric motions.

PREREQUISITES:

MET 303, MATH 402 or MATH 405; or consent of Instructor.
