  1. aerosol
    a propellant gas
  2. blizzard
    A severe snowstorm with high winds and low visibility
  3. ball lighting
    A rare and little known kind of lightning having the form of a moving globe of light that persists for periods of up to a minute.
  4. AGL
    above ground level
  5. Brisk
    winds 15-25mph
  6. albedo
    The proportion of the incident light or radiation reflected by a surface, typically that of a planet or moon.
  7. calm
    A condition when no air motion is detected
  8. altimeter
    instrument for measuring altitude
  9. ceiling
    upper limit of clouds
  10. celsius
    temperature scale
  11. altostratus
    Cloud forming a continuous uniform layer that resembles stratus but occurs at medium altitude, usually 6,500–23,000 feet
  12. circulation
    atmospheric flow
  13. cloud base
    For a given cloud or cloud layer, that lowest level in the atmosphere at which the air contains a perceptible quantity of cloud particles
  14. angular momentum
    The quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.
  15. cold-air funnel
  16. A funnel cloud is a funnel-shaped cloud of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a cumulonimbus or towering cumulus cloud) but not reaching the ground or a water surface
  17. anvil cloud
    a tall, distinctively anvil-shaped thundercloud
  18. confluence
    An act or process of merging
  19. cyclogenesis
    Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low pressure area)
  20. convergence
    A location where airflows or ocean currents meet, characteristically marked by upwelling (of air) or downwelling (of water)
  21. depression
    A region of lower atmospheric pressure, esp. a cyclonic weather system
  22. cyclone
    A system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression
  23. downburst
    A strong downward current of air from a cumulonimbus cloud, usually associated with intense rain or a thunderstorm
  24. visibility
    how far a person can see
  25. vortex
    A mass of whirling fluid or air, esp. a whirlpool or whirlwind
  26. wall cloud
    a roughly circular, rotating cloud that protrudes from the base of a thunderstorm cloud; it is often the beginning of a tornado.
