One of the keys to safe and successful naval operations in the tropics is an understanding of tropical meteorology. The Tropical Cyclone Reference Guide is designed primarily as a ready reference for weather forecasters required to provide tropical meteorology support to staff commanders. This chapter provides a comprehensive overview of forecast guidance used for tropical cyclone motion. Subjects discussed include global and regional numerical models, major warning center operations, tropical cyclone forecast aids, and their applications. The major reference of this chapter is Jeffries et al., (1993).
