Proposal Title: Mid-latitude ionospheric disturbances associated with Atlantic hurricanes and
tropical storms
ABSTRACT:
Ionosonde observations suggest that tropospheric storms can a ect the upper atmosphere, speci cally the
F-region. Identifying and describing the coupling between the ionosphere and other atmospheric regions is vital to
the overall understanding of observed ionospheric variations. The following proposed measurements by the Arecibo
Observatory will be combined with other measurements in an on-going CEDAR post-doc research project. The
radar observations will supply additional information regarding the coupling between tropospheric disturbances,
speci cally Atlantic hurricanes and tropical storms, and the lower thermosphere/ionosphere region. The objective
of the radar- portion of the study is three-fold: 1) Observe possible e ects of hurricanes and tropical depressions
on the F-region ionosphere, 2) Ascertain whether the tropical storms produce observable gravity wave
propagation into the thermosphere, and 3) Determine if gravity waves or electric elds are more likely to produce
F-region disturbances.
