ASUCA: The JMA Operational Non-hydrostatic Model

Operational use of ATOVS radiances in global data assimilation at JMA

1. Introduction The Advanced TIROS Operational Vertical Sounder (ATOVS) radiances have been operationally assimilated in the Japan Meteorological Agency (JMA) global 3D-Var data assimilation system since 28 May 2003. It replaced TOVS/ATOVS retrievals, which had been assimilated in the JMA global data assimilation system. The direct assimilation of ATOVS radiances is superior to its retrieval as...

Validation of hydrostatic and non-hydrostatic versions of the hydrodynamical model MIKE 3 applied for the Baltic Sea

Hydrostatic and non-hydrostatic versions of the hydrodynamic model MIKE 3 were used to hindcast hydrophysical fields in the Baltic Sea for the period 1 April–1 November 1996. The model results were compared with observed sea level at Helsinki station and with temperature and salinity measured at monitoring stations in the Gulf of Finland and the Baltic Proper for the period 1 June–1 November 19...

A hydrostatic model of the Wirtz pump

Assessment of the non-hydrostatic effect on the upper atmosphere using a general circulation model (GCM)

[1] Under hydrostatic equilibrium, a typical assumption used in global thermosphere ionosphere models, the pressure gradient in the vertical direction is exactly balanced by the gravity force. Using the non-hydrostatic Global Ionosphere Thermosphere Model (GITM), which solves the complete vertical momentum equation, the primary characteristics of non-hydrostatic effects on the upper atmosphere ...
