Venus’ extreme surface heat drives swirling winds in upper atmosphere, study finds

Scientists have shown how the swirling winds and searing heat on Venus work together in a revealing new study. The surface of Venus is hot enough to melt lead with temperatures averaging 872 degrees Fahrenheit (467 degrees Celsius). This extreme heat is maintained by a thick atmosphere of carbon dioxide that traps the heat on the planet in a greenhouse effect. This atmosphere also sports acid sulfuric clouds and a perpetual, swirling windstorm. In a new study, researchers reveal new insights into this planet’s strange wind and heat.
