The more we can learn about the Arctic and the Antarctic, the more we’re going to understand weather that impacts us directly here in the mid-latitudes. He said that those of us at mid-latitudes might be most familiar with the effects of polar winds when an Arctic blast of cold weather blows in. The term for that particular area of weather and that aspect of the global circulation that influences the movement of storms is we have all heard the jet stream. The jet stream is like a river of strong wind high above the Earth that steers storms around the world. And I think probably the most important connection between high latitude and lower latitude weather is the position of the jet stream. He uses this wind information to analyze the jet stream, and help predict global weather. Now the difference that the winds make in the position of the jet stream may seem relatively minor to the layperson. But in fact a difference of a few tens of kilometers actually makes a huge difference in the weather.
