LEAD: In 2016 the European Space Agency, ESA, will launch a ‘first-of-its-kind' satellite to measure key elements in the earth's wind fields.
1. The Aeolus satellite, named after the mythical Greek god of the winds, will measure worldwide upper level winds to help improve weather and climate forecasts.
2. NASA recently helped ESA calibrate its new wind instrument by taking simultaneous wind measurements with two Doppler lidars aboard its DC-8 aircraft.
TAG: The flights focused over the Arctic since this area holds particular interest due to the continued rise in Arctic temperatures.

The Polar Jet Stream Over Asia, 2010
Read moreMeandering 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. This pattern propagates across the mid-latitudes of North America, Europe and Asia, as pockets of cold air sporadically creep down from the Arctic—creating contrasting waves and flows that accelerate eastward due to Earth's rotation. This visualization was adapted from The Polar Jet Stream (#3864) by special request, using weather and climate observations from NASA's MERRA data model from 2010 for the period of the floods in Russia and the droughts in Pakistan. ||
