Solar influence on the Indian Ocean Monsoon through dynamical processes
نویسنده
چکیده
[1] The result of paleoclimate studies on the relationship between the Indian monsoon and solar activity, inferred from the analysis of stalagmites in Oman, is confirmed by using a modern meteorological dataset from 1958–1999. The present result suggests that the solar influence on monsoon activity is not due to a change in radiative heating in the troposphere but, rather, originates from the stratosphere through modulation of the upwelling in the equatorial troposphere, which produces a north-south seesaw of convective activity over the Indian Ocean sector during summer. Higher precipitation over Arabia and India, thus, occurs during high solar activity.

A 780-year annually resolved record of Indian Ocean monsoon precipitation from a speleothem from south Oman
[1] Meteorological records of monsoon rainfall in the Indian Ocean are generally less than 100 years long. The relative brevity of these records makes it difficult to investigate monsoon variation on decadal and centennial timescales, to determine what factors influence the intensity of rainfall on these timescales, or to place possible changes in the twentieth century into a broader historical...

The pattern of 3D circulation of the Wind-driven surface currents, Sea surface temperature (SST) and Sea Surface Salinity (SSS) distribution in the Northern Indian Ocean using The MIT general circulation model (MITgcm) with ho...
متن کاملVariability of Air–Sea Interactions over the Indian Ocean Derived from Satellite Observations
Novel ways of monitoring the large-scale variability of the southwest monsoon in the Indian Ocean are presented using multispectral satellite datasets. The fields of sea surface temperature (SST), surface latent heat flux (LHF), net surface solar radiation (SW), precipitation (P), and SW 2 LHF over the Indian Ocean are analyzed to characterize the seasonal and interannual variability with speci...
متن کاملAdvancing dynamical prediction of Indian monsoon rainfall
[1] Despite advances in seasonal climate forecasting using dynamical models, skill in predicting the Indian monsoon by such methods has proven poor. Our analysis identifies a flaw in the hitherto popular design of prediction systems in which atmospheric models are driven with a projected ocean surface temperature. Such a configuration presupposes Indian monsoon variability to be a consequence s...
متن کاملA Mathematical Model for Indian Ocean Circulation in Spherical Coordinate
In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...
