BEIJING, March 9 (Xinhua) -- The following is a summary of published science and technology news of China.

PRECIPITATION FORECAST

Chinese researchers have recently made strides in improving precipitation forecast using a novel approach that combines physics and artificial intelligence (AI).

The study, published in the journal Geophysical Research Letters, was conducted by a research team led by the Institute of Atmospheric Physics of the Chinese Academy of Sciences.

According to the study, in the AI era, pure data-driven meteorological and climate models are gradually catching up with, and even surpassing, traditional numerical models. However, significant challenges persist in current deep learning models, which hinder the predictive capabilities for complex weather and climate phenomena, including precipitation.

CHONGQING SMART FACTORIES

In SANY (Chongqing) Industrial Park, situated in Liangjiang New Area of southwest China's Chongqing Municipality, a large excavator rolls off from the smart production line every 17.3 minutes on average, with minimal human presence as robots are handling most tasks.

More than 700 robots are involved in welding and other tasks, enabling the production lines to operate primarily without human intervention, including assessment, according to Deng Jinghui, general manager of SANY Heavy Industry (Chongqing) Co., Ltd. "The extensive use of intelligent equipment allows a workforce of just 300 workers to manage 24 production lines, yielding an annual output of over 5 billion yuan (about 700 million U.S. dollars)."

XINJIANG HIGH-TECH FIRMS

Northwest China's Xinjiang Uygur Autonomous Region had 1,911 high-tech enterprises in 2023, spanning fields such as smart agriculture, new energy, and new materials, hitting a record high, local authorities said on Friday.

The number of small and medium-sized scientific and technological enterprises reached 2,256 in Xinjiang in 2023, an increase of 80.2 percent year on year, said the regional science and technology department. It added that the turnover of the region's technology contracts exceeded 7.37 billion yuan (around 1.04 billion U.S. dollars) last year, a year-on-year increase of 130 percent. Enditem
