Jet Stream
An area of strong winds that are concentrated in a relatively
narrow band in the upper troposphere of the middle latitudes and
subtropical regions of the Northern and Southern Hemispheres.
Flowing in a semi-continuous band around the globe from west to
east, it is caused by the changes in air temperature where the cold
polar air moving towards the equator meets the warmer equatorial
air moving polarward. It is marked by a concentration of isotherms
and strong vertical shear.
Aero-Linx: Aviation Digital
Data Service
The Aviation Digital Data Service (ADDS) makes available to the
aviation community text, digital and graphical forecasts, analyses,
and observations of aviation-related weather variables.
"Gathering information from accidents is vitally
important to further improve the safety of flying. Various
technical means for reinforcing flight data recovery and data
transmission to ground centers are principally available. We will
now study different options for viable commercial solutions,
including those where our experience with real-time data
transmission from our own test aircraft could support the further
development of such solutions."
