Earth-sun Distance Dramatically Alters Seasons In The Equatorial Pacific In A 22,000-year Cycle
Weather and climate modelers understand pretty well how seasonal winds and ocean currents affect El Niño patterns in the eastern equatorial Pacific Ocean, impacting weather across the United States and […]

Analysis of the Planetary Mass Uncertainties on the Atmospherical Retrieval Accuracy
The properties of the atmospheres of the exoplanets depend on several interconnected parameters, making it difficult to determine them.

A Discovery That Could Dramatically Narrow The Search For Extraterrestrial Life
An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a […]

The Key Factors Controlling the Seasonality of Planetary Climate
Several different factors influence the seasonal cycle of a planet. This study uses a general circulation model and an energy balance model (EBM) to assess the parameters that govern the […]
