The Weather of April 2022 – An extremely dry and sunny April


With dry northeast monsoon affecting Hong Kong and less moisture supply to the south China coast for most of the time in the month, April 2022 was much drier than usual in Hong Kong. The total rainfall in the month was 3.5 millimetres, only about 2 percent of the normal figure of 153.0 millimetres and the lowest on record for April. The month was also much sunnier than usual, the total duration of bright sunshine in the month was 191.1 hours, about 69 percent above the normal.



Massive amount of water found below Antarctica’s ice sheet for 1st time


Hidden deep below the ice sheet that covers Antarctica, scientists have discovered a massive amount of water. The groundwater system, found in deep sediments in West Antarctica likely to be the consistency of a wet sponge, reveals an unexplored part of the region and may have implications for how the frozen continent reacts to the climate crisis, according to new research.



Climate change: Key UN finding widely misinterpreted


In the latest IPCC climate report, researchers wrote that greenhouse gases are projected to peak “at the latest before 2025”. This implies that carbon could increase for another three years and the world could still avoid dangerous warming. But scientists say that’s incorrect and that emissions need to fall immediately.



沖頂珠峰 使命必達——氣象服務保障“巔峰使命2022”珠峰科考成功登頂

“札西德勒!”“天公作美!”看到從前方傳回的登頂畫面,海拔5200米的珠峰大本營裡氣氛歡騰。而有這麼一小波人,他們在歡呼過後,迅速投入下一階段的工作——為科考登山隊員回撤提供氣象保障。他們是由中科院青藏高原研究所、中國氣象科學研究院和西藏自治區氣象局等單位組成的“西風-季風協同作用及影響分隊”,也是承擔此次珠峰科考氣象保障任務的權威專家團隊。



8830米!為什麼要在地球之巔建氣象站?

去年以來,珠峰科考專家和科考登頂隊員克服重重困難,在海拔5200米至8300米的珠峰北坡,陸續建成運行7套自動氣象觀測站。5月4日12時46分許,一套重達50公斤的自動氣象觀測站,在珠穆朗瑪峰北坡海拔8830米處架設成功,即時資料傳回正常。這是世界上海拔最高的自動氣象觀測站,刷新了中國自動氣象觀測站的架設高度紀錄,獲取的實測資料填補了珠峰極高海拔氣象記錄空白,同時也意味中國珠峰梯度氣象觀測體系初步建成。



Extremely high pre-monsoon temperatures over Pakistan and northern India


April 2022 was globally around the sixth warmest April since records began. April temperatures over much of Europe were close to average values for 1991-2020. Temperatures were unusually high from north-eastern Africa across the Middle East to central and southern Asia. Pre-monsoon temperatures were extremely high over Pakistan and northern India.



Climate change and farming driving insect decline


Insect numbers have plunged by half in some parts of the world due to climate change and intensive agriculture, a study has found. The combined pressures of global heating and farming are driving a “substantial decline” of insects across the globe, according to UK researchers. They say we must acknowledge the threats we pose to insects, before some species are lost forever.



NASA’s EMIT will map tiny dust particles to study big climate impacts


NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission, set for launch in June, aims to deepen researchers’ understanding of these fine particles of soil, silt, and clay from Earth’s deserts and, ultimately, how they affect climate. Researchers at NASA and elsewhere have long focused on dust’s flight. Its atmospheric impacts are included in climate models, but it remains unclear whether dust has a net warming or cooling effect on the planet, and how this is changing over time(video).



粵港澳大灣區初步建成溫室氣體監測網


近日,廣東省中山市溫室氣體觀測站建設完成。截至目前,全省有廣州、佛山、肇慶、中山等地12個網站可以即時獲取高精度大氣二氧化碳濃度觀測資料,粵港澳大灣區溫室氣體監測網初步建成。下一步,省氣象局將持續推動廣州番禺、惠州、江門、東莞溫室氣體觀測站建設,並在粵東、粵西兩翼及粵北生態區遴選具有代表性的溫室氣體站址,並啟動建設工作。除此之外,韶關新豐國家大氣本底站已具備觀測系統安裝條件,將繼續完成設備安裝後開展業務運行。



Life below water: Interactive status of world coral reefs


The Status of Coral Reefs of the World: 2020 is a report by the Global Coral Reef Monitoring Network, a network of the International Coral Reef Initiative. Its findings show that between 2009 and 2018 there was a progressive loss of about 14 per cent of the coral from the world’s coral reefs primarily caused by recurring, large-scale bleaching events. In all, about 11,700 square kilometres of hard coral, which is more than all the coral currently living on Australia’s coral reefs, were lost.
