This study employed three newly developed global coupled climate models to study the impact of
horizontal atmospheric model resolution (tile size) on precipitation extremes.
Not exact matches
The resolution of the
atmospheric model is set to TL159L91 (IFS version 41r2), which corresponds to a 1.125 °
horizontal grid (125 km) with 91 vertical levels going up to 0.1 hPa.
(In comparison,
horizontal resolutions in most of the global
atmospheric models referenced in the IPCC's 4th assessment are of the order of 100 - 300 km).
The eastward component of the wind in the lower troposphere (850 hPa) simulated by an
atmospheric model with roughly 50 km
horizontal grid.
However, while the
horizontal resolution of 2.5 ° (T42) or better in the
atmospheric component of many coupled
models is probably adequate to resolve most important features, the typical vertical resolution of around 20 levels is probably too low, particularly in the
atmospheric boundary layer and near the tropopause.
