South Asian summer monsoon variability: a modelling study with the atmospheric regional climate model HIRHAM5
… directly affected by the caprices of the South Asian summer monsoon rainfall. India receives around 78 % of the annual precipitation during the June-September months, the summer monsoon season of South Asia. But, the monsoon circulation is not consistent throughout the entire summer season. …

The Impact of a Warmer Climate on Atmospheric Circulation with Implications for the Asian Summer Monsoon
… of the Indian Ocean region can impact the South Asian Summer Monsoon (SASM) system. In these simulations, the dynamic monsoon intensity experienced the greatest decrease with tropical warming alone. Lesser SASM weakening occurred when both tropical and high latitude warming were imposed. Given …

Observational study of the monsoonal dynamics and eddy shedding phenomena
… upper tropospheric dynamics in the area of the Asian summer monsoon. We look at summers of four years from 1987 to 1990. The divergent upper tropospheric circulation of the monsoon often adopts the form of a unified large-scale vortex. However, when the vortex becomes elongated enough, so that …

Long-range statistical forecasting of Korean summer precipitation
… statistical forecasting methods for Korean summer precipitation (KSP). We reviewed existing literature on the East Asian summer monsoon to develop a background on current KSP research and on the relationship of KSP to climate variations. Second, we explored interannual variability of KSP …

Eddy shedding from non-axisymmetric, divergent anticyclones with application to the Asian Monsoon anticyclone
The Asian summer Monsoon circulation is driven by differential thermal heating, primarily associated with the localized latent heat release from enhanced precipitation over the India sub-continent. Although this heating is of limited zonal extent, it drives a time-averaged, upper level anticylone …

Regional dynamical downscaling and analysis of water balance across different regions and time scales
… westerlies and the effects of the East Asian Summer Monsoon. We find that the basin's water balance in the mid-Pliocene was influenced by the strengthened mid-latitude westerlies and by the East Asian Summer Monsoon reaching farther west into the QB. For the BB area, we present the …

Uncertainties in climate data analysis
… uncertainty. The recurrence analysis of the East Asian Summer Monsoon during the last 9000 years confirms the well-known `dry' events at 8200 and 4400 BP, plus an additional significantly dry event at 6900 BP. We also analyze the network of dependencies surrounding GMT. We find an intricate, …

Extremes in events and dynamics : a nonlinear data analysis perspective on the past and present dynamics of the Indian summer monsoon
… extreme changes in the dynamics of the Indian Summer Monsoon (ISM) in the past, I propose a new approach based on the quantification of fluctuations of a nonlinear similarity measure, to identify regimes of distinct dynamical complexity in short time series. I provide an analytical derivation …

Aerosol-cloud-precipitation interaction based on remote sensing and cloud-resolving modeling over the Central Himalayas
… orographic precipitation related to the South Asian summer monsoon, typically occurring from June to September. Atmospheric aerosols can influence regional and global climate through aerosol-radiation (ARI) and aerosol-cloud interactions (ACI). The study of the aerosol-precipitation …

Late glacial to Holocene climate and vegetation changes on the Tibetan Plateau inferred from fossil pollen records in lacustrine sediments
… influence on the climate in this region, the Asian Summer Monsoon (ASM) and its evolutionary history are of vital importance for accurate predictions. However, neither the evolutionary pattern of the summer monsoon nor the driving mechanisms behind it are yet clearly understood. For this …

Layer-layer interactions in atmospheric, cryospheric, and stellar dynamics
… of lower stratospheric temperatures above the Asian summer monsoon anticyclone is found to obey quasigeostrophic theory. Lower stratospheric monsoon temperatures from both radiosondes and reanalysis have been cooling over the observational record, suggesting enhanced upwelling through the …

On the structure and dynamics of the Asian monsoon anticyclone
The Asian summer monsoon circulation has been the subject of continuous research for several decades. Much emphasis has been given to the lower level cyclone, but while various models and mechanisms have been proposed to explain certain features of the upper level anticyclone, like the zonal scale …
