Abstract: The dynamics of error growth in a two-layer nonlinear quasigeostrophic model has been studied to gain an understanding of the mathematical theory of atmospheric predictability. The growth of random errors of varying initial ...

Abstract: The space?time structure of the active and break periods of the Indian monsoon has been studied using 70-yr-long high-resolution gridded daily rainfall data over India. The analysis of lagged composites of rainfall anomalies ...

Abstract: hree regionally coupled experiments are conducted to examine the role of Indian and Pacific sea surface temperature (SST) in Indian summer monsoon intraseasonal variability using the National Centers for Environmental ...

Abstract: 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 ...

Abstract: he space?time structure of the leading monsoon intraseasonal oscillation (MISO) in three-dimensional diabatic heating is studied. Using the ERA-Interim data of the European Centre for Medium-Range Weather Forecasts, the ...

Abstract: We define the slow manifold S in the state space of a primitive-equation model as a hypothetical invariant manifold on which there is no gravity-wave activity. and on which unique velocity-potential and streamfunction ...

Abstract: The relation between the intraseasonal modes of the South Asian monsoon and the sea surface temperature (SST) in the tropical oceans on a daily time scale has been investigated. Long lead?lag relations of the daily SST ...

Abstract: The tropical disturbances formed in the Bay of Bengal and the Arabian Sea and over land points in central India, known as low pressure systems (LPSs), are shown to contribute significantly to the seasonal monsoon rainfall ...

Abstract: Empirical evidence is presented to support a hypothesis that the interdecadal variation of the Indian summer monsoon and that of the tropical SST are parts of a tropical coupled ocean?atmosphere mode. The interdecadal ...
