Core Viewpoint - The "Global Kilometer-Scale Numerical Simulation Hackathon 2025" Beijing node aims to address cutting-edge challenges in climate simulation, enhancing the development of next-generation Earth system models and providing critical scientific support for climate change response [1][4]. Group 1: Event Overview - The Beijing node is one of nine global nodes and is organized by the Institute of Atmospheric Physics, Chinese Academy of Sciences, in collaboration with the Max Planck Institute for Meteorology [2]. - The event will take place from May 12 to May 16, gathering nearly 100 researchers to collaborate on climate simulation innovations [9]. Group 2: Scientific Focus - The hackathon will focus on nine scientific topics, including the Asian monsoon process in 2020, extreme precipitation during the Meiyu period in 2020, and mechanisms of compound high-temperature drought events [4]. - Key regional scientific issues such as extreme precipitation, typhoon anomalies, and climate events in the Pan-Polar region will be addressed, leveraging China's advantages in complex terrain simulation and Asian monsoon research [4]. Group 3: International Collaboration - Teams from seven countries, including China, the USA, the UK, Brazil, Germany, Japan, and Australia, will collaborate using advanced global models to analyze simulation data [5]. - The event emphasizes community collaboration, open access, and the establishment of unified data standards to enhance climate research [5]. Group 4: Impact on Climate Science - Kilometer-scale climate simulation is at the forefront of Earth system science, crucial for improving extreme weather predictions and assessing climate change risks [6]. - Research outcomes from the Beijing node will be integrated into a global collaboration network, providing data standards and methodologies to accelerate the translation of climate science into policy actions [8].

曾庆存："搞科学的要真有科学的样子。第一，我要想到学科怎么发展。第二，国家怎么需要。" 曾庆存，1935年生，广东阳江人，今年90岁。中国科学院院士、国际著名⼤气科学家、国家最高科学技术 奖得主。他创立的"半隐式差分法"是世界上首个用原始方程直接进行实际天气预报的方法，这一算法如今仍是 世界数值天气预报核心技术的基础。曾庆存在气象领域取得诸多"零的突破"，为气象卫星遥感作出开创性贡 先生，不仅是一种称谓，更蕴含着敬意与传承。 可堪先生之名者，不仅在某一领域独树一帜，更有着温润深厚的德性、豁达包容的胸襟，任风吹雨打，仍 固守信念，将深沉的家国情怀根植于血脉之中。 捧着一颗心来，不带半根草去，为后生晚辈持起读书、做人的一盏灯。 中国之声特别策划《先生》，向以德性滋养风气的⼤师致敬、为他们的成就与修为留痕。 预测天气的背后，是一组包含⼤气运动、温度、气压、湿度、风向、风速等诸多变量的复杂方程。国际气 象科学界早就明确，想准确预报天气，就得求解⼤气运动的原始方程组，但在曾庆存之前，没人搞成过。 1957年，北京⼤学物理系毕业的曾庆存到莫斯科苏联科学院留学，他的导师、国际著名气象学家基别尔建 议他尝试解斜压⼤气动力学原 ...
