While wind shears in the upper atmosphere are usually vertical, they tend to be horizontal closer to the runway. Horizontal wind shears can create eddies or swirls, of air that cause turbulence. A microburst is a type of wind shear associated with a thunderstorm and caused by a current of sinking air.
Apple Music. Not to be confused with Apple Records. Apple Music is a music-streaming service, developed by Apple Inc. Users select music to stream to their device on-demand, or they can listen to existing, curated playlists.
To get Apple Music, your iOS device needs to be running iOS 8.4 or later. The iOS 8.4 update, which started rolling out in June 2015, changes the earlier Music app that came with your device into the Apple Music app. Whether you subscribe to Apple Music or not, the new Apple Music app will still be on your iPhone, iPad or iPod and you'll use it to manage music already on your device or that you've purchased from iTunes.
