Abstract
W. R. Piggott Although Dr Dudeney’s paper presents some preliminary results from the h.f. Doppler experiment in the Antarctic Peninsula which are interesting in themselves, the main objective of deploying the experiment in this part of the world was to take advantage of the special geophysical situation in the sector for a broader investigation. Our objectives included: ( a ) to study the relations between gravity waves and travelling ionospheric disturbances. ( b ) to see whether gravity waves could be associated with major weather systems, or with particular types of auroral particle precipitation. ( c ) to investigate whether F-region winds are modified during periods of auroral activity. ( d ) to search for possible F-region movements associated with magnetic field changes, e.g. sudden commencements. ( e ) if electric fields exist in the F-region in this zone, vertical movements due to them should be particularly easy to detect. The experiment thus forms part of the general British Antarctic Survey’s attack on the dynamics of the F-region.
