El Niño-Southern Oscillation (ENSO) is a climate phenomenon occurring every 2–7 years in the tropical Pacific Ocean, associated with changes in air pressure east to west.
A large team of researchers affiliated with multiple institutions in the U.S., Spain, France and Finland has found that frequent dust devils and daytime upslope winds are the reason for Mars's constant atmospheric haze. In ...
Planetary scientist Erdal Yiğit, with George Mason University, has published a Perspective piece in the journal Science suggesting that upper atmospheric interactions with solar wind cannot fully explain the loss of surface ...
The westerlies—or westerly winds—play an important role in weather and climate both locally and on a global scale, by influencing precipitation patterns, impacting ocean circulation and steering tropical cyclones. So, ...
