The STORMFURY eraAlso in 1961 the USN and USWB flew seeding experiments into Hurricane Esther. This lead to the formal organization of Project STORMFURY in 1962, as a joint venture of the USN, USWB, and the National Science Foundation. This Project would continue for more than twenty years and include NHRP, RFF and the USAF in its operations.A good deal of NHRP's research during the early years of STORMFURY were in areas critical to weather modification, such as cloud physics and storm structure and dynamics. Ironically, studies into natural hurricane variability would eventually lead to questions of the effectiveness of STORMFURY. Satellites had a dramatic impact on hurricane reconnaissance and research during the early 1960's. It was no longer necessary to send aircraft on long 'fishing expeditions', just looking for signs of tropical disturbances. Using the satellites forecasters could pinpoint where the Hurricane Hunters needed to fly. And researchers for the first time could watch the formation of a hurricane from the very start. New insights into storm genesis were also gained from this 'top-down' perspective. However, the high cirrus Central Dense Overcast of hurricanes still made it necessary to fly planes into these storms to collect information. The DC6s and some NHRP scientist reached out to the international meteorological community in 1963 and 1964 by participating in the International Indian Ocean Expeditions. This was the first in a long series of multi-national experiments to which the Project in its various forms was to contribute its expertise in tropical weather and in airborne meteorological observation. In 1964 NHRP was redesignated the National Hurricane Research Laboratory (NHRL) to signify a more permanent status. The Project was initially supposed to run for only a few years; time enough, it was thought, to answer all the basic questions about hurricanes. As the complex nature of tropical storms became apparent it was realized that hurricane research needed to be an on-going concern. It was already paying dividends in the development of statistical track forecast models and a storm surge forecast guide. This year also saw both NHC and NHRL move to the Computer Center Building on the University of Miami campus in Coral Gables, Florida. This move brought the government researchers into closer contact with the academic community and also brought access to the University's computer systems. The greater computing power lead to the development of a numerical storm surge model and to NHC-67, a statistical hurricane track forecast model that outperformed all rivals in 1966. That year the U.S. Government reorganized its earth science agencies into the Environmental Science Services Administration (ESSA). This included the USWB, NHC, RFF, and NHRL. Work began on multi-layer primitive equation track forecast models and on SANBAR, a dynamic physics model. Gordon Dunn and the staff of NHC published a paper evaluating the positive impact of the previous eight years of computer forecast models on track prognostications. Hurricane computer models were also used to simulate hurricane modification experiments to try to validate the field work of STORMFURY. In 1967 Dr. Gentry became Director of STORMFURY in addition to NHRL Director. This brought the Project under the direct management of NHRL and required a greater commitment of the Laboratory's personnel and resources. More restrictions were placed on where and when a hurricane could be a candidate for seeding and far fewer experiments were being flown. To increase the opportunity for candidate storms several attempts were made in the early 1970's to move Project STORMFURY's operations to the Pacific, but these plans were put aside each time. Improvements were made to the cloud physics instrumentation on the DC6 in 1968. And for the next two years a series of experiments were carried out which released tracers into hurricanes in an attempt to study the air flow by airborne radar. In the summer of 1969 the DC6s and several NHRL scientists participated in the Barbados Oceanographic and Meteorological Experiment (BOMEX), a huge multi-national, multi-agency scientific study set east of Barbados. This was the second in a series of such large scale experiments to which the Lab contributed. BOMEX's purpose was to better define the the atmospheric and air/sea interaction processes in the tropics, and hence a better understanding of the energy source of hurricanes.
The Department
of Commerce, in 1970, reorganized ESSA into the
National Oceanic and Atmospheric Administration (NOAA). This
included renaming the USWB the National
Weather Service (NWS), and separating the Environmental
Research Laboratories (ERL) from the NWS. The National Hurricane
Center was kept under NWS, the operational wing of NOAA, while
the research laboratories, including NHRL, were put into
ERL. |
