An estimated 5 million to 20 million tons of debris now floating in the ocean following Japan's massive tsunami is due to hit the shores Hawaii by early next year, before reaching the U.S. West coast sometime in 2014, according to estimates by University of Hawaii scientists. The projections have been validated by a Russian training ship, which spotted the debris in the Pacific Ocean where the scientists from the university's International Pacific Research Center predicted it would be....

El Nino and its partner La Nina, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Nino events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short instrumental record. An international team of climate scientists has now shown that annually resolved tree-ring records from North America, particularly from the US Southwest, give a continuous...

The huge tsunami triggered by the 9.0 Tohoku Earthquake destroyed coastal towns near Sendai in Japan, washing such things as houses and cars into the ocean. Projections of where this debris might head have been made by Nikolai Maximenko and Jan Hafner at the International Pacific Research Center, University of Hawaii at Manoa. Maximenko has developed a model based on the behavior of drifting buoys deployed over years in the ocean for scientific purposes. The debris first spreads out eastward...

Earth's global temperature has been rising gradually over the last decades, but the warming has not been the same everywhere. Scientists are therefore trying to pin down how the warming has affected regional climates because that is what really matters to people, and to adaptation and mitigation strategies. Their efforts, however, had hit a roadblock because the necessary observations of the winds over the oceans were biased. Developing a new method to remove the bias, Hiroki Tokinaga and...

Current state-of-the-art global climate models predict substantial warming in response to increases in greenhouse gases such as carbon dioxide. The models, though, disagree widely in the magnitude of the warming we can expect. The disagreement among models is mainly due to the different representation of clouds. Some models predict that global mean cloud cover will increase in a warmer climate and the increased reflection of solar radiation will limit the predicted global warming. Other...

Scientists have long known that atmospheric convection in the form of hurricanes and tropical ocean thunderstorms tends to occur when sea surface temperature rises above a threshold. The critical question is, how do rising ocean temperatures with global warming affect this threshold? If the threshold does not rise, it could mean more frequent hurricanes. According to a new study by researchers at the International Pacific Research Center (IPRC) of the University of Hawaii at Manoa (UHM), this...

The possible spread of the oil spill from the Deepwater Horizon rig over the course of one year was studied in a series of computer simulations by a team of researchers from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa. Eight million buoyant particles were released continuously from April 20 to September 17, 2010, at the location of the Deepwater Horizon oil rig. The release occurred in ocean flow data from simulations conducted with the...

The initial results of the first computer model that simulates the global atmosphere with a detailed representation of individual clouds have been analyzed by a team of scientists at the International Pacific Research Center (IPRC) at the University of Hawai`i at Mānoa, Japan-Agency for Marine Earth Science and Technology (JAMSTEC), and the University of Tokyo. The model, called the Nonhydrostatic ICosahedral Atmospheric Model (NICAM), was developed for the...

For over two centuries, meteorologists were puzzled by the observation that atmospheric pressure in the tropics peaks at 10 a.m. and 10 p.m. nearly every day. In the late 1960s, a theory was proposed that these surface pressure variations result from waves that are generated by the sun's heating of the upper atmosphere. The waves, called solar tides, propagate to the ground as they travel around the globe. Strong support for this theory has now been presented in a study by a US-Japan team of...
