| Zusammenfassung |
| We calculate a Lorenz energy budget for the martian atmosphere from Mars reanalysis data
derived from Mars Global Surveyor data for Mars Years 24 - 27. We present global, annual
mean energy and conversion rates and compare these to Earth data. While mean values per
unit area are consistently lower for Mars, due to the thinner martian atmosphere, the
directions of most energy conversion are similar to Earth. Further seasonal and
hemispheric decomposition reveals a strong influence of the cross-equator Hadley
circulationon the movement of atmospheric energy on Mars. On separating the
diurnal timescale contributions to the energy reservoirs and conversions suggests that
thermal tides make significant contributions to conversion terms and eddy kinetic
energy in the martian atmosphere, especially during planet-encircling dust storms. |
