Scientists Explore Roots of Future Tropical Rainfall

Analysis of the Last Glacial Maximum sheds light on climate models’ ability to simulate tropical climate change

How will rainfall patterns across the tropical Indian and Pacific regions change in a future warming world? Climate models generally suggest that the tropics as a whole will get wetter, but the models don’t always agree on where rainfall patterns will shift in particular regions within the tropics.

A new study, published online May 19 in the journal Nature Geoscience, looks to the past to learn about the future of tropical climate change, and our ability to simulate it with numerical models. (more…)

Scientists Probe Indian Ocean for Clues to Worldwide Weather Patterns

*Study how tropical weather brews in the Indian Ocean and moves eastward along the equator*

An international team of researchers will begin gathering in the Indian Ocean next month, using aircraft, ships, moorings, radars, numerical models and other tools to study how tropical weather brews there and moves eastward along the equator, with reverberating effects around the globe.

The six-month field campaign, known as DYNAMO or Dynamics of the Madden-Julian Oscillation, will help improve long-range weather forecasts and seasonal outlooks and enable scientists to further refine computer models of global climate. (more…)
