Effects of Climate Modes on Interannual Variability of Upwelling in the Tropical Indian Ocean

In the tropical Pacific and Atlantic Oceans, easterly trade winds prevail and upwelling occurs in the eastern equatorial basin. In contrast, the Indian Ocean is subject to intense seasonally reversing monsoon wind forcing, and the annual mean prevailing winds in the equatorial basin. This provides unique features of interannual variability of the upwelling in the tropical Indian Ocean.

Robust late twenty-first century shift in the regional monsoons in RegCM-CORDEX simulations

The paper uses an unprecedented ensemble of regional climate model (RCM) projections over seven regional CORDEX domains to provide, for the first time, an RCM based global view of monsoon changes at various levels of increased greenhouse gas (GHG) forcing.

Monsoons Climate Change Assessment

A new article was published in the Bulletin of the American Meteorological Society that reviews the current knowledge on detection, attribution and projection of global and regional monsoons (South Asian, East Asian, Australian, South American, North American, and African) under climate change. 

An experimental protocol for global ocean-sea-ice model simulations and its evaluation: The Ocean Model Intercomparison Project phase 2 (OMIP-2)

A new framework for global ocean-sea-ice model simulations based on phase 2 of the Ocean Model Intercomparison Project (OMIP-2), was presented recently by CLIVAR Ocean Model Development Panel (OMDP) and other ocean model communities.

Atmospheric Convection and Air-Sea Interactions over the Tropical Oceans: Scientific Progress, Challenges and Opportunities

From 7-9 May 2019, 90 observational and modeling experts met in Boulder CO, USA to review and document progress, identify outstanding issues, and propose approaches for future integrated process studies in atmospheric convection and air-sea interactions over the tropical oceans, over a broad range of spatio-temporal scales.
