Book Description
The release of 10 to the 26th power molecules of sulfur hexafluoride at 220-km altitude generated an ionospheric hole which lasted about 30 minutes. Rate equations are set up and solved to explore the time and space variation of electron densities within the region. It is shown that due to the geomagnetic-field-constrained diffusion of electrons, the estimated lifetime of the hole is much longer than if unhindered radial diffusion could take place, and that the estimated lifetime is commensurate with the observed lifetime. A more quantitative comparison between the theoretical model and the observational data is possible only if the rate constants and the radio frequency sounder characteristics are specified more closely than is currently possible.

Book Description
The cumulus cloud events of the Florida peninsula that were observed during a 19-day period of photoreconnaissance in August and September 1957 are described and illustrated. The associated meteorological and rainfall events are also described and the intercorrelations among the various observations are pointed out. The study findings revealed that the principal factors governing the cloud and rainfall situations of the different days were (1) the low-level advection of water vapor into the peninsula from the oceanic surroundings, (2) the wind transport, into the heated peninsula from the oceans during the daytime, of pre -existing cumulus populations containing appreciable liquid water, (3) the low-level convergence, and associated updraft motion, engendered by the synoptic situation and the peninsula sea breezes, and (4) the precipitable water content of the lower Florida air mass.
