Stochastic and oscillatory forcing of global atmospheric angular momentum

Atmospheric Loss during High Angular Momentum Giant

Introduction. During the end stage of planet formation , terrestrial planets are expected to experience a number of giant impacts. Understanding how much of the planet's atmosphere is lost to space during such collisions is vital to be able to determine the origin and evolution of planetary atmospheres. Recently, geo-chemical observations [1, 2] and high angular momentum models for the Moon-for...

Response of a global atmospheric circulation model to spatio-temporal stochastic forcing: ensemble statistics

The response of a simplified global atmospheric circulation model (PUMA) to spatiotemporal stochastic forcing is analyzed using the statistical measures originally developed for ensemble forecast evaluation. The nontrivial effects of time and length correlations of the stochastic forcing on the ensemble scores (e.g. spread and ‘error’) are studied. A maximum for these scores is observed to occu...

2 Exercise. Prove it. ◦ In fact, as sophisticates can show you, on a complex space a linear operator which preserves all norms will also preserve all inner products. But the key thing is to remember is that a unitary operator preserves all inner products (and therefore all norms). • This is analogous to the fact that translations and rotations in ordinary three-dimensional space preserve distan...
