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.
For the music that isn't available in iTunes, like obscure tracks or music from a local band, Apple Music will upload those files to your iCloud account so that you can stream it from the app. Songs you upload don't count towards your iCloud storage limit, but you can only upload 25,000 songs currently.
