Scientists from the Institute of Oceanology, Chinese Academy of Sciences (IOCAS) studied targeted observation with respect to ENSO (El Niño-Southern Oscillation) events using an intermediate coupled model developed by IOCAS. They found that observing the central equatorial Pacific favors an improvement in prediction skill. When removing the initial condition errors in the central equatorial Pacific, ENSO prediction errors can be reduced by 25 percent.
Ancient rainfall records stretching 550,000 years into the past may upend scientists' understanding of what controls the Asian summer monsoon and other aspects of the Earth's long-term climate. Milankovitch theory says solar heating of the northernmost part of the globe drives the world's climate swings between ice ages and warmer periods. The new work turns Milankovitch in its head by suggesting climate is driven by differential heating of the Earth's tropical and subtropical regions.
Tropical Cyclone Mekunu, the second tropical cyclone in less than a week, formed in the western Arabian Sea early on May 22, 2018 and is moving toward a landfall in Oman. NASA satellites provided an infrared, night-time and precipitation analysis of the storm.
Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
A highly precise method to determine past typhoon occurrences from giant clam shells has been developed, with the hope of using this method to predict future cyclone activity.
The oldest ice core so far provides 800,000 years of our planet's climate history. A field survey in Antarctica has pinpointed a location where an entire million years of undisturbed ice might be preserved intact.
Visible satellite imagery from NASA's Aqua satellite revealed that Tropical Cyclone 02A, now renamed Mekunu has continued to consolidate and organize off the coast of Oman in the Arabian Sea.
Many farmers grow corn and soybean in rotation to avoid the continuous corn yield penalty, but now there's another reason to rotate. Scientists at the University of Illinois have provided further evidence that rotating crops increases yield and lowers greenhouse gas emissions compared to continuous corn or soybean.
A new study shows the Earth's climate would increase by 4 degrees Celsius, compared to pre-industrial levels, before the end of 21st century. The study also projects precipitation changes in association with a 4 degrees Celsius global warming above the pre-industrial period using the available RCP8.5 experiments of CMIP5 models.
By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to Meteorology Professor Shawn M. Milrad of Embry-Riddle Aeronautical University.
