Interannual Variability of Summer Monsoon Onset over the Western North Pacific and the Underlying Processes

Climatological summer monsoon onset over the South China Sea (SCS) and the western North Pacific (WNP) (defined as the region of 108–208N, 1208–1608E) displays three distinct stages. Around mid-May, monsoon rain commences in the SCS and the Philippines. In early to mid-June, the monsoon rain extends to the southwestern Philippine Sea. After mid-July, the rainy season starts in the northeastern ...

Dynamics of ’Internal’ Interannual Variability of the Indian Summer Monsoon in a GCM

Seasonal mean prediction and predictability experiments with General Circulation Models (GCM’s) indicate that a significant fraction of observed interannual variability (approximately 50% or more) of the Indian summer monsoon may be due to ’internal’ low frequency variability (Goswami, 1998). Potential predictability studies with long observations also indicate similar contribution of ’internal...

Extension of potential predictability of Indian summer monsoon dry and wet spells in recent decades

An understanding of the limit on potential predictability is crucial for developing appropriate tools for extended-range prediction of active/break spells of the Indian summer monsoon (ISM). The global low-frequency changes in climate modulate the annual cycle of the ISM and can influence the intrinsic predictability limit of the ISM intraseasonal oscillations (ISOs). Using 104-year (1901–2004)...

Impact of variability in the Indian summer monsoon on the East Asian summer monsoon

We report on model experiments that support the hypothesis that the second mode of variability of the East Asian Summer Monsoon is influenced by the variability of the Indian Summer Monsoon. The results suggest that the recent trend towards drier conditions in northern China in summer is, at least partly, a consequence of the synchronous drying trend over India in summer noted by some authors. ...
