The technique referred to as "dynamical downscaling", which involves the use of regional climate models to dynamically infer the effects of large-scale climate processes at local scales, has proved to be an effective way to simulate precipitation at high resolution. Moreover, with advancements in supercomputing capabilities, dynamical downscaling is now progressing to the kilometer scale.

Two meteorological satellites, along with their ground application systems, have officially started operation, said the China Meteorological Administration on Thursday. The trial operation of the two satellites, Fengyun-3E (FY-3E) and Fengyun-4B (FY-4B), began in June this year. They will provide observation data and application services to global users. The FY-3E, launched on July 5

When it comes to making real-time decisions about unfamiliar data - say, choosing a path to hike up a mountain you've never scaled before - existing artificial intelligence and machine learning tech doesn't come close to measuring up to human skill. That's why NASA scientist John Moisan is developing an AI "eye." Moisan, an oceanographer at NASA's Wallops Flight Facility near Chincoteague,

The James Webb Space Telescope lit up 2022 with dazzling images of the early universe after the Big Bang, heralding a new era of astronomy and untold revelations about the cosmos in years to come. The most powerful observatory sent into space succeeds the Hubble telescope, which is still operating, and began transmitting its first cosmic images in July. "It essentially behaves better th

How fast do electrons inside a molecule move? Well, it is so fast that it takes them just few attoseconds (1 as = 10-18 s or one billionth of billionth of a second) to jump from one atom to another. Blink and you missed it - millions of billions of times. So measuring such ultrafast processes is a daunting task. Scientists at the Australian Attosecond Science Facility and the Centre for Qu

A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact - which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago - in a shallow ocean region, according to a study published in Scientific Reports. Previous research has proposed that an asteroid or comet impact within an ocean in the Martian northern lowla

Chinese scientists have completed the life-cycle growth experiments of rice and Arabidopsis in the Chinese space station and successfully obtained their seeds, said the Chinese Academy of Sciences (CAS) on Monday. With the safe landing of the Shenzhou-14 spaceship's return capsule at the Dongfeng landing site Sunday night, the seeds of rice and Arabidopsis, which have undergone a 120-day l

SpaceX is rolling out a new business called Starshield to support U.S. military applications, building upon the company's existing satellite system. The latest Elon Musk endeavor expands on Starlink Internet satellite technology for national security uses, to include secure communications and space surveillance payloads, for its largest customer, the Pentagon. "While Starlink is
