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.
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.
Magma steadily emerges between oceanic plates. It pushes the plates apart, builds large underwater mountains and forms new seafloor. This is one of the fundamental processes that constantly change the face of the Earth. But there are also times when new seabed is created without any volcanism, by un-roofing mantle material directly at the seafloor. Scientists led by GEOMAR, Germany have published the first estimation based on seismic data on how much seafloor is produced this way.
Today, only the eldest inhabitants of the Danube Delta recall that, in the past, you could skate on the river practically every winter; since the second half of the 20th century, Europe's second-largest river has only rarely frozen over.
In the journal Temperature, researchers outline how quickly hot cars become deadly for children.
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.
Experimentalists conducted a simulation of future conditions in the Red Sea caused by global warming and acidification, while simultaneously increasing levels of nutrients such as nitrate and phosphate. They found that when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. Algal dominance over corals in the reef means losing all of the beauty and biodiversity of the coral reefs.
The dashboard of a car parked in the sun on a hot summer day can reach 70°C in about an hour. One hour is also about how long it can take for a young child to suffer heat injury or even die from hyperthermia -- when the body warms to above 40°C and cannot cool down.
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.
