Geography and photography. Two seemingly distinct fields that actually share many common traits. From studying geography to becoming a landscape photographer, the presentation is about how geography guided my approach and became a central part of my photography.

Extreme-value theory is the branch of statistics that studies rare events. In the last decades, its popularity within the climate sciences has been growing, driven by the increasing awareness that extreme climate events will intensify in frequency and magnitude in view of climate change.

This thesis aims to perform a comprehensive and systematic investigation of the climate response in the two hemispheres to astronomical parameters, CO2 and Northern Hemisphere (NH) ice sheets, as well as the half-precession cycles, during the interglacials of the past 800 ka mainly based on snapshot and transient simulations using the LOVECLIM model.

Reconstructions of Holocene Optimum (HO) in East Asian summer monsoon (EASM) regime from speleothem versus other proxy records have yielded divergent phase relationships with the EASM and local precipitation. This apparent discrepancy has been partly attributed to the uncertainties in the climatic representation of Chinese speleothem oxygen isotope (δ18O) records.

In rotating fluids, the Coriolis force acts as a restoring force that can support oscillations known as inertial waves. One important example are Rossby waves existing in the Earth’s thin atmospheric and oceanic layers. The dispersion relation and profile of those waves can be derived mathematically by treating the fluid layer as thin compared to the planet’s radius.

Mixed forests often have higher productivity, stress resistance and temporal stability of productivity than comparable pure forests. Several mechanisms for this have been described: competition release, facilitation and competitive dominance of a highly productive species.
