Large scale of the west Pacific warm pool will be discussed on the basis of existing data and information. A definition of the warm pool in terms of an isothermal layer is simple and definitive in the vertical, but difficult with regard to its horizontal extent. Even if narrowly defined by the 28°C isotherm, the pool undergoes large annual variations in its horizontal extent. The region of overlap is only about one half of the size of the pool. The pool is persistent only between 10°N and 10°S with its center at 170°E. An inspection of the circulation of upper layer indicates that the pool gains water from the anticyclonic gyres, and discharges warm water by means of the countercurrent and the Indonesian throughflow. The residence time of water in the pool is only 1.3 years and makes the pool sensitive to interannual variations of heat advection and heat input. Three seems to be little interhemispheric exchange of water through the pool.
