why study winds
Why Study Winds?
  • Winds are the most important variable studying dynamics and transport in the atmosphere.
  • Wind measurements are critical to improvement of numerical weather prediction models.
  • Global wind measurements are essential to NASA’s Earth Science Enterprise mission.
  • They can be used to study planetary atmospheric dynamics.
  • Commercial and military aircraft would benefit from clear air wind shear detection as well.
