BEIJING, April 12 (Xinhua) -- The following is a summary of published science and technology news of China.
AI WEATHER FORECAST
Chinese researchers have developed an advanced artificial intelligence (AI) weather forecast system, pushing global medium-range weather forecasts beyond 10 days.
The system, FengWu, is based on deep learning architecture of multi-model and multi-task, capable of generating high-precision global meteorological forecast results for the next 10 days in 30 seconds.
Compared with the traditional physical models, FengWu reduces the error by 19.4 percent and extends the forecast range to 10.75 days based on reanalysis data, according to the Shanghai Artificial Intelligence Laboratory, one of its developers.
NEW GALEASPID SPECIES
Researchers have discovered a new fossilized galeaspid species with "nine tails" in south China's Guangxi Zhuang Autonomous Region. This is the world's first galeaspid fossil with a well-preserved tail.
According to the researchers from the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences, they named the new species as Foxaspis novemura because its caudal fin is comprised of nine ray-like scale-covered digitations, just like that of the Nine-Tailed Fox, a mythical animal from an ancient literature "Shan Hai Jing" (Classic of Mountains and Seas).
The fossil specimen completely preserves the caudal fin in both folded and flared states, revealing its morphological details to the greatest extent, according to Gai Zhikun, a research professor from the institute.
NEW ENERGY STORAGE
According to a report recently issued by China Energy Storage Alliance (CNESA), by the end of 2022, China's cumulative installed capacity of new energy storage reached 13.1 gigawatts, with an annual growth rate of 128 percent.
New energy storage refers to energy-storage technologies other than conventional pump storage, including lithium-ion batteries, liquid flow batteries, flywheel, compressed air, hydrogen and ammonia, as well as heat and cold energy storage.
The report also showed that the world's cumulative installed capacity of new energy storage reached 45.7 gigawatts by the end of 2022, rising 80 percent year on year. ■
