Our planet’s cloudiness has been heretofore understood as being controlled by the slowly varying, large scale, atmospheric circulation known as the Hadley cell. In this video, CLAUDIA STEPHAN argues that this model is overly simplistic. * Bringing recent measurements taken over the Atlantic into dialogue with observational data gathered in Darwin on gravity waves, Stephan suggests that relationships between clouds and atmospheric waves can provide important insight into, and ultimately improve, weather and climate modeling. * This LT Publication is divided into the following chapters: 0:00 Question 2:11 Method 5:00 Findings 6:30 Relevance 7:53 Outlook
