In recent years, dynamic development of the renewable energy sources (RES) market has been seen, particularly in the micro-installation segment, i.e. systems chosen by owners of small households and business entities. However, as investors point out, the accounting system for energy produced by various types of installations is often unfavourable due to the “unpredictability” of individual RES sources. The digital Atlas of small-scale wind energy developed by IMGW-PIB and the Wrocław University of Technology will help producers better manage resources and generation capacity.
On May 15, the first set of images of FENGYUN-3G (FY-3G), China's first precipitation measurement satellite, was released to the public. The monitoring images of 6 payloads onboard FY-3G showed the three-dimensional structure of different layers of precipitation, which can enable better monitoring and forecasting of severe precipitation systems. The Ku/Ka-band dual-frequency precipitation measurement radar is the main payload onboard FY-3G, which is mainly used for precipitation monitoring of severe weather systems. It can clearly observe the internal three-dimensional structure of precipitation systems like typhoon, rainstorm and blizzard. During a severe convective weather process in South China on May 7, FY-3G clearly captured the three-dimensional structure of the rain and cloud system.
The western regions of Libya have been affected since Monday evening 8 / 5 / 2023 by a Saharan depression of 1002 hPa, which was accompanied by active south-westerly winds to strong speed reaching 70 km/hour, and leading to a decrease in horizontal visibility to less than 200 meters in most areas.
The US National Oceanic and Atmospheric Administration has recently updated a fact sheet on the “State of the Science on Atlantic Hurricanes and Climate Change”.
