Holocene variations in the strength of the Indian Monsoon system
The monsoon is an important component of the Earth’s climate system. It played a vital role in the development and sustenance of the largely agro-based economy in India. A better understanding of past variations in the Indian Summer Monsoon (ISM) is necessary to assess its nature under global …

Tropical climate variability from the last glacial maximum to the present
… Atlantic. The second is the strength of the Indian Monsoon, an important component of both tropical and global climate. Long-term variations in the position of the ITCZ in the Atlantic region are determined using both organic geochemical techniques and climate modeling. Upwelling in Cariaco …

On intrinsic uncertainties in earth system modelling
… trendsetting field of climate research, i.e. the Indian monsoon. For the systematic analysis concerning the different facets of uncertainty, a box model of the Indian monsoon is investigated, which shows a saddle node bifurcation against those parameters that influence the heat budget of the …

Aridification of the Indian subcontinent during the Holocene : implications for landscape evolution, sedimentation, carbon cycle, and human civilizations
The Indian monsoon affects the livelihood of over one billion people. Despite the importance of climate to society, knowledge of long-term monsoon variability is limited. This thesis provides Holocene records of monsoon variability, using sediment cores from river-dominated margins of the Bay of …

Forcings on Coccolithophore Evolution and Assemblage Changes
… reveals their sensitivity to changes in the Indian monsoon system and the El Niño–Southern Oscillation. I utilize this baseline information to assess the impacts of a volcanic supereruption and a warm interstadial–cold stadial climate transition on the marine ecosystem. Primary productivity …

Satellite derived rainfall over tropical Africa : its pattern variability and calibration
… over eastern Africa with an extended axis in the Indian Ocean (25.8%). A strong relationship exists between the zonal wind and rainfall modes at the seasonal time scale. The dominant mode for the intra-seasonal rainfall is loaded over northern Congo (29%). The second and third modes are over …

SURFACE AND AEROSOL EFFECTS ON THE SOUTH ASIAN MONSOON HYDROCLIMATE
… targets important couplings in the South Asian monsoon system at interannual or longer time-scales and associated processes and mechanisms: aerosol-hydroclimate, atmosphere-ocean, and land-atmosphere. Anomalous springtime absorbing aerosols loading over the Indo-Gangetic Plain (IGP) leads to …

Modulation of South African summer rainfall by global climatic processes
… side) to a teleconnection-type of behaviour (Indian Ocean side). Rainfall variations during the late summer months show significant (and negative) links with SST fluctuations within the equatorial/tropical Pacific and Indian Ocean areas and are consistent with results obtained in analyses with …

Geospatial Analysis of Droughts, Rice and Wheat Production, and Agrarian Vulnerability: A District-Level Study of the self-calibrated Palmer Drought Severity Index in India
… Surface Temperatures (SST) have heated in the Indian Ocean, drought patterns across South Asia have changed; the Indian monsoon has become more volatile and less predictable. In this study, monthly self-calibrated Palmer Drought Severity Index (sc-PDSI) data for the time period between 1950 and …

What can we learn from climate data? : Methods for fluctuation, time/scale and phase analysis
… El Nino/Southern Oscillation (ENSO) and the Indian Monsoon on inter-annual time scales is studied by means of Hilbert transformation and a curvature defined phase. This method allows one to investigate the relation of two oscillating systems with respect to their phases, independently of …

Simulation der indischen Monsunzirkulation mit dem Regionalen Klimamodell HIRHAM
In dieser Arbeit wird das regionale Klimamodell HIRHAM mit einer horizontalen Auflösung von 50 km und 19 vertikalen Schichten erstmals auf den asiatischen Kontinent angewendet, um die indische Monsunzirkulation unter rezenten und paläoklimatischen Bedingungen zu simulieren. Das Integrationsgebiet …

The use of 10Be surface exposure dating of erratic boulders in the reconstruction of the late Pleistocene glaciation history of mountainous regions, with examples from Nepal and Central Asia
… the Nepal Himalaya seems to be controlled by the Indian monsoon rather than the westerly circulation. Only in the MIS 2, the westerly jetstream appears to have shifted as far south as to affect glaciation all over the Himalaya. During the Younger Dryas, the eastern limit of the influence of the …

Modeling large-scale singular climate events for integrated assessment
Erkenntnisse aus paläoklimatologischen Studien, theoretischen Betrachtungen und Modellsimulationen deuten darauf hin, dass anthropogene Emissionen von Treibhausgasen und Aerosolen zu großskaligen, singulären Klimaereignissen führen könnten. Diese bezeichnen stark nichtlineare, abrupte …
