Intraseasonal and Interannual Variability of Rainfall over India
A gridded daily rainfall dataset prepared from observations at 3700 stations is used to analyze the intraseasonal and interannual variability of the summer monsoon rainfall over India. It is found that the major drought years are characterized by large-scale negative rainfall anomalies covering nearly all of India and persisting for the entire monsoon season. The intraseasonal variability of ra...
متن کاملAnalysis of Intraseasonal and Interannual variability of the Asian summer monsoon using a Hidden Markov Model
Intraseasonal and interannual variability of Asian summer monsoon rainfall in pentad precipitation data is examined using a hidden Markov model (HMM). The spatial patterns of discrete rainfall states derived with the HMM and the associated transition probabilities between the states are shown to represent well the principal Asian summer monsoon intraseasonal oscillation (ISO), propagating eastw...
متن کاملInterannual Variation in Indochina Summer Monsoon Rainfall: Possible Mechanism
Indochina is located between two extensively researched components of the Asian monsoon system: the Indian subcontinent and southeast–east Asia. Highly correlated with the National Oceanic and Atmospheric Administration Niño-3 sea surface temperatures, the interannual variation of Indochina monsoon rainfall is caused by a mechanism different from the two aforementioned regions. This mechanism c...
متن کاملDecadal change in intraseasonal variability over the South China Sea
[1] Evidence is presented to reveal a decadal change around mid-1990s in the behavior of intraseasonal variability (ISV) over the South China Sea (SCS). During 1979–1993, the ISV has a spectral peak around 64 days, which is longer than in the recent epoch of 1994–2007 (around 42 days). The ISV event in 1979–1993 involves a merging process of the northward and westward propagating convection ano...
متن کاملInterannual 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 ...
