Abstract

The Effective Atmospheric Angular Momentum (EAAM) is a combined project from the Met Office and the European Centre for Medium Range Weather Forecasting (ECMWF). The data is of 3 angular momentum components of the mass and wind terms at 12 or 24 hourly intervals. The Met Office data are from 1983-1997. The corresponding ECMWF data cover the period 1979 to 1993. This dataset is public.

Process overview

This dataset was generated by the computation detailed below.
Title Met Office operational unified model (UM) deployed on Met Office Computer network
Abstract This computation involved: Met Office operational unified model (UM) deployed on Met Office Computer network. The Unified Model is the name given to the suite of atmospheric and oceanic numerical modelling software developed and used at the Met Office. The formulation of the model supports global and regional domains and is applicable to a wide range of temporal and spatial scales that allow it to be used for both numerical weather prediction and climate modelling as well as a variety of related research activities. The Unified Model was introduced into operational service in 1992. Since then, both its formulation and capabilities have been substantially enhanced.
