Global model

A new 15-level NWP model was implemented in 1982 using a development of the 10-level model dynamical core for a latitude-longitude grid with physical parametrizations derived from the General Circulation Model developed for research during the First GARP Global Experiment (FGGE) in the late 1970s.

It was rapidly extended to a global capability to provide military support following the invasion of the Falkland Islands in 1982.
