A dipole mode in the tropical Indian Ocean

Nature, 1999
For the tropical Pacific and Atlantic oceans, internal modes of variability that lead to climatic oscillations have been recognized, but in the Indian Ocean region a similar ocean-atmosphere interaction causing interannual climate variability has not yet been found.

Tropical oceanic intraseasonal variabilities associated with central Indian Ocean mode

Climate Dynamics, 2021
The oceanic intraseasonal variabilities (ISVs) are pronounced over the tropical Indian Ocean. Recently, a Central Indian Ocean (CIO) mode was proposed as an ocean–atmosphere coupled mode at intraseasonal timescales. It has a close relation with northward-propagating ISVs and intraseasonal precipitation during the Indian summer monsoon.

Atmospheric energetics over the tropical Indian Ocean during Indian Ocean dipole events

Climate Dynamics, 2018
The evolution of atmospheric perturbation potential energy (PPE) over the tropical Indian Ocean is analyzed during a composite positive IOD event using reanalysis datasets for the period 1948–2015. The IOD modulates the variation in PPE, which then affects perturbation kinetic energy (PKE) through energy conversion.

Coupled Ocean-Atmosphere Variability in the Tropical Indian Ocean

2013
The Indian Ocean Dipole (IOD) is a natural ocean-atmosphere coupled mode that plays important roles in seasonal and interannual climate variations. The coupled mode locked to boreal summer and fall is distinguished as a dipole in the SST anomalies that are coupled to zonal winds.

Intraseasonal oscillation in the tropical Indian Ocean

Advances in Atmospheric Sciences, 2005
The features of the intraseasonal oscillation (ISO) of the tropical Indian Ocean are studied using several sources of observational data. It is shown that there are intraseasonal oscillations in the tropical Indian Ocean, but their periods vary with latitude: the major period is about 20–30 days in the equatorial region, about 30–50 days at 10°N/10°S ...

The Influence of Tropical Indian Ocean SST on the Indian Summer Monsoon

Journal of Climate, 2007
AbstractThe Indian summer monsoon (ISM) is one of the main components of the Asian summer monsoon. It is well known that one of the starting mechanisms of a summer monsoon is the thermal contrast between land and ocean and that sea surface temperature (SST) and moisture are crucial factors for its evolution and intensity.

Extended Prediction of North Indian Ocean Tropical Cyclones

Weather and Forecasting, 2012
Abstract This analysis examines the predictability of several key forecasting parameters using the ECMWF Variable Ensemble Prediction System (VarEPS) for tropical cyclones (TCs) in the North Indian Ocean (NIO) including tropical cyclone genesis, pregenesis and postgenesis track and intensity projections, and regional outlooks of tropical

Tropospheric dryness and clouds over tropical Indian Ocean

Atmospheric Research, 2006
Dry layers in the free troposphere over Tropical Oceans have been studied for their role in convective activity and for their effects in the radiation budget. Previous studies concentrated, mostly, on the Western Pacific region because of the abundance of observations during the TOGA-COARE.
