Antennas, probably at Greenbury Point, Maryland, in about 1920. These were U. S. Navy communications antennas meant to communicate with Europe during the First World War and probably also with ships. Perhaps this slide was meant to illustrate the potential of wireless radio communication for weather dissemination. From an old-fashioned glass lantern slide.

Preparing to launch a meteorological kite. Note attached meteorograph on kite.

Kite operations at Dodge City Weather Bureau kite station. The person on the right is Clarence W. Canfield, the kite-reeler. The other two individuals from left to right are probably George Todd and W. S. Beldere (sp.?).

A strong supercell thunderstorm drops hail, with the WSR-88D Doppler radar at New Underwood, SD in the foreground.

The driveway to the WSR-88D at NWS WFO DTX is usually barren and lonely, but not on the day of the NOAA In The Great Lakes open house. Instead, the hilltop trail was turned into a parking lot for the over-500 guests that were hosted.

Hurricane Abby approaching the coast of British Honduras. Note the complete eyewall cloud.

A non-tornadic spiral shaped radar echo is apparent in the lower left quadrant of the scope image. Observed on AFB CPS-9 PPI scope. The spiral echo is about 90 miles southwest of radar location. The set was on long pulse (5 microsecond) and the antenna was elevated 1 degree.

Photo # 1 Meriden, Kansas, tornado as seen on Topeka Weather Bureau WSR-3 radar. Topeka Weather Bureau WSR-3 radar. The classic hook patterns as seen on radar were indicative of a tornado. However, absence of a hook did not preclude presence of a tornado. This tornado destroyed Meriden, Kansas. Monthly Weather Review, June 1962, p. 236.
