Abstract: Cloud condensation nuclei (CCN) at cloud base strongly affect the droplet concentration at cloud base, which in turn influences the life history of a cloud. There are usually more nuclei over land than over water because ...

Abstract: Radar populations of seedable clouds observed between 4.57 km (15,000 ft) and 7.62 km (25,000 ft) each hour were gathered near Miami and Tampa during various months through the year. They show that numbers of tops in this ...

Abstract: Oceanic cloud populations were photographed from the R. V. Crawford stationed near 13N, 55W during a 22-day period in August?September 1963. A panoramic series of six pictures per hour was taken with a Hasselblad camera ...

Abstract: here is a major difference in population-weighted lightning fatality rates between the lower fatality rates in developed countries and the higher fatality rates in developing countries. The large decrease in annual rates ...

Abstract: ational maps of cloud-to-ground lightning flash density (in flashes per square kilometer per year) for one or more years have been produced since the National Lightning Detection Network (NLDN) was first deployed across ...

Abstract: New techniques in holography allow standard motion picture film to be converted to holograms that are visible with standard light sources. Time-lapse photographs of clouds have been converted to two types of holograms. One ...

Abstract: The effects on potential heating, cooling and water demand induced by the shift and growth of population from cooler and wetter regions of the country to warmer and drier areas were examined. Heating and cooling degree day ...

Abstract: Eight flash flood events occurred in the Tucson area of southeastern Arizona during the 1990 summer when a high-resolution lightning detection network was operated in the region. A total of 3479 cloud-to-ground lightning ...

Abstract: Long-term changes in the number of lightning deaths from 1900 to 1991 have been examined for the contiguous United States. The population-normalized series revealed an exponential decrease in the number of deaths per million ...
