In April 2021, China Meteorological Administration (CMA) began the operation of an upgraded global numerical weather prediction (NWP) system — GRAPES_GFS V3.1. The major physical improvements are outlined as follows: 1. Methane Oxidation Scheme - 2. Land surface model - 3. Moist physical processes

The 2021 “AI Earth” Artificial Intelligence Innovation Challenge—AI Helps Accurate Weather and Ocean Forecast was organized in early February 2021 by WMO RTC Nanjing and International Association of Meteorological Education and Sciences (IAMES), an international consortium advocated by Nanjing University of Information Science and Technology (NUIST) and supported by over 30 universities and institutes focusing on Atmospheric Science, Hydrology, Environmental Science and other Meteorology related disciplines. On April 22, 2021, during the World Earth Day, the Final of the Competition was held at WMO RTC Nanjing, China.
March 2021 was warmer than normal in temperatures and below-average precipitation. The mean temperature of the month was 23.1°C which is 1.8°C above the long-term normal for March and this goes on record as the fourth-highest mean monthly temperature for March since 1902 and exceeded by March 2018 with a record of 24.6°C, March 1969 with a record of 24.2°C and March 2010 with a record of 23.7°C.
Un nouveau record officiel de température maximale quotidienne, pour un mois de mars, a été enregistré aujourd'hui le 31 mars 2021 à Clemency avec une valeur de 25,4°C. Avec une température de 25,4°C à Clemency, 25,3°C à Obercorn, 25,2°C à Remerchen et 25,0°C à Remich, ce mercredi est non seulement le premier jour d'été de cette année (plus de 25 degrés), mais c'est également la première fois qu'un tel pic de chaleur a été enregistré en cette période de l'année.
Climate change will greatly affect water availability over the course of the year. The Hydro-CH2018 hydrological scenarios show that, at certain times and in certain regions, this vital resource will become so scarce or so warm that humans will have to curb their activities and nature will suffer. With climate change mitigation, the changes will be much smaller, meaning that such mitigation is worth the effort. Systematic protection of waters as well as careful planning and management will enable the challenges to be dealt with more effectively.
