"description": "Meandering around the planet like a rollicking roller coaster in the sky, the Northern Hemisphere's polar jet stream is a fast-moving belt of westerly winds that traverses the lower layers of the atmosphere. The jet is created by the convergence of cold air masses descending from the Arctic and rising warm air from the tropics. Deep troughs and steep ridges emerge as the denser cold air sinks and deflects warm air regions north, giving the jet stream its wavy appearance.

"description": "Powerful winds whip around Earth, affecting the planet's weather and climate. Such winds make up the Northern Hemisphere’s polar and subtropical jet stream. Undulating in the sky miles above the surface, these rapidly moving air currents flow eastward like rivers in the atmosphere. The polar jet stream travels in the mid-latitudes while the subtropical jet stream passes near the tropics. Sometimes the jets converge or park above a region. In summer 2010, the polar jet stream shifted north and lingered for more than two months over Eurasia. A stationary high-pressure area developed as a result that disrupted the normal movement of weather systems. This contributed to extreme drought in Russia and devastating floods in Pakistan. Watch the video to see a NASA visualization that shows the motions of winds above Europe and Asia during these events. || ",

"description": "LEAD: What has happened to summer? The summer’s temperatures for much of U.S. (except the western U.S. coast) are cooler than normal. This, following the bitter polar vortex chill back in January. What’s going on? 1. One of many driving forces of this weather (besides El Niño, NAO, PDO, etc.) might be the jet stream’s interaction with the Arctic Ocean. 2. The Arctic is warming at twice the rate of the rest of the world, partly because the sea ice is melting, allowing the sun to warm up the ocean water. 3. But more open water means more evaporation and clouds. Will more clouds act as cooling sun umbrellas, or warming blankets in the future? NASA’s new ARISE mission onboard the flying C-130 laboratory will look for some answers this coming September. TAG: The peak of the Arctic sea ice melt usually happens in mid-September. Expect new NASA images then. || WC_ARISE-1920-MASTER_iPad_1920x018000177_print.jpg (1024x576) [122.7 KB] || WC_ARISE-1920-MASTER_iPad_1920x0180_print.jpg (1024x576) [132.4 KB] || WC_ARISE-1920-MASTER_iPad_1920x0180_searchweb.png (320x180) [62.5 KB] || WC_ARISE-1920-MASTER_iPad_1920x0180_web.png (320x180) [62.5 KB] || WC_ARISE-1920-MASTER_iPad_1920x0180_thm.png (80x40) [4.5 KB] || WC_ARISE-1920-MASTER_WEA_CEN.wmv (1280x720) [11.0 MB] || WC_ARISE_edit3.avi (1280x720) [12.0 MB] || WC_ARISE-1920-MASTER_baron.mp4 (1920x1080) [11.5 MB] || WC_ARISE-1920-MASTER_iPad_960x540.m4v (960x540) [70.6 MB] || WC_ARISE-1920-MASTER_iPad_960x540.webmhd.webm (960x540) [2.5 MB] || WC_ARISE-1920-MASTER_1920x1080.mov (1920x1080) [689.2 MB] || WC_ARISE-1920-MASTER_iPad_1280x720.m4v (1280x720) [127.4 MB] || WC_ARISE-1920-MASTER_NBC_Today.mov (1920x1080) [247.4 MB] || WC_ARISE-1920-MASTER_prores.mov (1920x1080) [544.2 MB] || WC_ARISE-1920-MASTER_1280x720.mov (1280x720) [766.5 MB] || WC_ARISE-1920-MASTER_iPad_1920x0180.m4v (1920x1080) [246.8 MB] || ",
