Multi-task machine learning improves multi-seasonal prediction of the Indian Ocean Dipole

Nature Communications, 2022
A multi-task learning model is proposed to improve seasonal-to-annual prediction of the Indian Ocean Dipole (IOD). This model captures the inter-basin interactions between ENSO and IOD and distinctive precursors of positive and negative IOD events.

Analyzing of the Indian Ocean Dipole (IOD) phenomena in relation to climate change in Indonesia: a review

Journal of Physics: Conference Series, 2021
Abstract IOD is another parameter that affects climate change, especially in tropical areas such as Indonesia. IOD is a global phenomenon that occurs due to differences in sea surface temperature anomalies in the western and eastern parts of the Indian Ocean. This paper aims to review several articles that discuss the Indian Ocean Dipole

Seasonal Evolution of Chlorophyll-a in the North Indian Ocean Associated with the Indian Ocean Dipole and Two Types of El Niño Events

Journal of Marine Science and Engineering, 2022
To investigate the main modes of interannual variation of chlorophyll-a (Chla) with seasonal evolution and its variation cycle in the North Indian Ocean based on satellite-derived products during 1998–2016, a season-reliant empirical orthogonal function (

Intensity changes of Indian Ocean dipole mode in a carbon dioxide removal scenario

npj Climate and Atmospheric Science, 2022
The Indian Ocean Dipole/Zonal mode (IOD) is an interannual phenomenon over the tropical Indian Ocean, causing a pronounced impact worldwide. Here, we investigate the mechanism of the change in IOD characteristics in a CO2 removal simulation for an earth ...

Predictability of sea surface temperature anomalies at the eastern pole of the Indian Ocean Dipole—using a convolutional neural network model

Frontiers in Climate, 2022
In this study, we train a convolutional neural network (CNN) model using a selection of Coupled Model Intercomparison Project (CMIP) phase 5 and 6 models to investigate the predictability of the sea surface temperature (SST) variability off the Sumatra ...

Spectral Analysis and SARIMA Model for Forecasting Indian Ocean Dipole (IOD) and Rainfall in West Aceh Regency

Journal of Physics: Conference Series, 2021
Abstract Indian Ocean Dipole (IOD) in the Indian Ocean is one of the climatic phenomena that affects climate conditions in western Indonesia. West of Aceh Regency is one of the districts in Aceh Province which borders and faces the Indian Ocean directly, so it has a significant impact due to climate events caused by the IOD phenomenon ...

GCM simulations of the Indian Ocean dipole influence on East African rainfall: present and future. [PDF]

, 2007
Six coupled GCMs are assessed in terms of their ability to simulate observed characteristics of East African rainfall, the Indian Ocean dipole and their temporal correlation. Model results are then used to analyze the future behaviour of rainfall and the

Influence of internal climate variability on Indian Ocean Dipole properties [PDF]

, 2018
The Indian Ocean Dipole (IOD) is the dominant mode of interannual variability over the tropical Indian Ocean (IO) and its future changes are projected to impact the climate and weather of Australia, East Africa, and Indonesia.

Systematic biases over the equatorial Indian Ocean and their influence on seasonal forecasts of the IOD. [PDF]

Clim Dyn
Accurate seasonal prediction of the Indian Ocean Dipole (IOD) is crucial given its socioeconomic impacts on countries surrounding the Indian Ocean. Using hindcasts from the Met Office Global Seasonal Forecasting System (GloSea6), coupled mean-state ...

Simulation of the Indian Ocean Dipole: A relevant criterion for selecting models for climate projections [PDF]

, 2011
A multi-model average shows that 21st century warming over the eastern Indian Ocean (IO) is slower than that to the west, but with strong inter-model variations.
