Numerical weather prediction is performed using the Unified Model software suite.

Temporary observatories set up in 1904 in Busan, Incheon, Mokpo and elsewhere were precursors to the current KMA.

In April 1978, CMO was renamed the Korea Meteorological Service (KMS).

The Seoul and Busan observatories were recognized as Centennial Observing Stations in 2017 by the World Meteorological Administration (WMO).

In 2013, US-based Enterprise Electronics Corporation (EEC) out of Enterprise, Alabama won a contract to deliver 11 S-band Klystron Dual-Polarization Doppler Weather radar systems to the KMA.
