A numerical investigation of diabatically induced stationary waves in northern winter season was carried out by using a linear steady state spectral model with primitive equations in global domain. It was focused on inter-hemispheric connections of stationary wave behaviour in response to several cases of idealized thermal forcings centred in different latitudes. The results showed that the thermally forced stationary waves in one hemisphere might propagate across the equator into the other hemisphere, and thus contribute substantially to the maintenance and variation of the stationary waves in both bendspheres.
