  3. WWII Radars

  4. After WWII Meteorologists Experimented with Military Radars: Thunderstorms and Convection Clearly Seen

  5. Hurricanes Also Apparent-Eye Wall, Rainbands

  6. In the late 1950’s a national meteorological radar network was established (WSR-57).

  7. WSR-57 (no Doppler capability)

  8. During the 1970s and early 80s a lot of experimentation with Doppler Radars • Provides speed of object towards or away from the radar • Can show wind shifts and circulations • Particularly useful for showing the rotation in severe convection—the mesocyclone

  9. In the late 1980s, the NWS put in a network of Doppler Weather Radars NEXRAD WSR88D (Weather Surveillance Radar 88 Doppler)

  10. Sound of train passing: http://www.fourmilab.ch/cship/sounds/doppler.au

  11. Big Radar Advance in 2011: Dual-Polarization
