Internal Heat Drives Jupiter’s Giant Storm Eruption

Detailed analysis of two continent-sized storms that erupted in Jupiter’s atmosphere in March 2007 shows that Jupiter’s internal heat plays a significant role in generating atmospheric disturbances. Understanding this outbreak could be the key to unlock the mysteries buried in…

La Nina Rainfall Patterns

La Niña, the counterpart to El Niño, alters rainfall patterns over the Pacific and Indian Ocean basins. La Niña develops when stronger-than-average trade winds push the warm surface waters of the equatorial Pacific west. Since cold water rises to replace…

Kyushu, Japan

Part of the Pacific “Ring of Fire, ” Japan sits at the intersection of at least four tectonic plates: the Pacific, the Philippine Sea, the North American, and the Eurasian. As a result, Japan sports a complex landscape of mountains,…

Small Tropical Cyclones Contribute More to Annual Rainfall

Though relatively infrequent, tropical cyclones make a significant contribution to the seasonal accumulation of rainfall in the southeastern United States. In a recent study, Dr. Marshall Shepherd and collaborators at the University of Georgia found that tropical storm systems contribute…

Ramsar Convention and Wetlands in Vietnam

Composed of salt-loving trees, bushes, and shrubs, mangrove forests play critical roles in providing waterfowl habitat and preventing coastal erosion. Because the areas they occupy are also viable for aquaculture, however, these watery forests face continual pressure from development. One…

The Dawn of a New Solar Cycle

On January 4, 2008, the new sunspot—about the width of the Earth, but small by Sun standards—appeared in the Sun’s Northern Hemisphere, with its north magnetic pole (red area) pointing to the right and its south magnetic pole (blue) pointing…

La Nina Still Going in January 2008

La Niña conditions often follow El Niño in the cycle known as the El Niño/Southern Oscillation (ENSO). La Niña episodes are marked by stronger-than-normal easterly trade winds and below-normal sea surface temperatures in the eastern tropical Pacific Ocean. These changes…
