The 39 tornado occurrences associated with the four hurricanes which struck bhe United States during 1964 are shown to favor a location in the right front quadrant of the storm. A distribution of hurricane tornadoes over the past 10 yr. is presented, also favoring the right front quadrant. Some suggestion of a preference for afternoon formation is rejected because a time bias was noted in reports from hurricane Isabell.
In 1958 Atlantic Coastal radars performed a historic feat by continuously tracking two hurricanes--Daisy and Helene--for 500 nautical miles. The manner of accomplishment is discussed for each. The use of logarithmic spiral overlays on the radar PPI scope to locate the eye of Daisy is illustrated. Photographs are presented showing hurricane Helene as it appeared on the WSR-1 radar at Charleston, S.C., and on the more powerful SP-1M at Cape Hatteras, N. C. Personal observations of the author, who operated the SP-1M radar at the Weather Bureau Office, Cape Hatteras, with another radar meteorologist, during the passage of the hurricanes, are presented. In 1958 two Atlantic hurricanes, Daisy and Hclene, were kept under constant surveillance for 500 nautical miles by coastal radars, the first time such a feat had been accomplished. It was made possible by interagency cooperation involving the Weather Bureau, the Navy, the Air Force, NACA, and the University of Miami. A summary of earlier information on hurricane tracking leading to this development may be found in papers by Wexler [1947] and Rockney [1956]. The tracking of the two hurricanes is discussed separately in the following paragraphs. Hurricane Daisy, August 2•-29, 1958--Daisy was first detected as a tropical storm about 300 miles east-northeast of Miami, Florida, on August 24, 1958. The next day Daisy developed into a hurricane and moved very slowly northward for about 2 days. During the evening of August 27, the small but intense hurlcane accelerated northward, continuing at an accelerated pace during the next day. On August 29, Daisy curved northeastward off the New Jersey coast. The track of the hurricane is given in Figure 1. The numbered positions are dates for the 7:00 A.•. locations of the storm's center.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
