How asteroid, comet strikes may have delayed evolution of atmosphere（图）
小行星 彗星撞击 大气科学 高层大气物理学
2023/6/21
Between 2.5 and 4 billion years ago, a time known as the Archean eon, Earth’s weather could often be described as cloudy with a chance of asteroid.
Back then, it was not uncommon for asteroids or com...
A 1000-year simulation with the IPSL ocean-atmosphere coupled model
coupled climate model long-termclimate simulation oceanic overturning circulation model drift
2015/9/17
A 1000-year climate simulation is run with the ocean-atmosphere coupled model developed at the Institute Pierre-Simon Laplace (IPSL, Paris). No flux adjustment is used. The drift of the model is analy...
