THREE SCIENTISTS ACCEPT FIVE-YEAR APPOINTMENTS
Three NCAR scientists--Paul Crutzen, William Holland, and Richard Somerville-- recently accepted five-year appointments at NCAR. Last week, they spoke to Staff Notes about their scientific interests.
Paul Crutzen
"I don't think humanity will permit adverse human impact on the stratosphere to grow into a major problem," Paul Crutzen says. Although his modeling work on the effect of fluorocarbons on the ozone layer in the stratosphere has re- ceived a great deal of attention, it would be wrong to say that Paul Crutzen has sounded an alarm. His thoughtful optimism is the opposite of alarmism.
"This problem will probably not exist in ten years," he states. Then he smiles. "I'm a little bit worried, working in a field which is suddenly so popular. It's easy to lose one's perspective. When I began to do this research, I wasn't inter- ested in some immediate application. I simply wanted to explain something about an important region of the atmosphere, the ozone layer, and the processes that go on within it. What little literature there was seemed to consist of the copying and recopying of inaccurate statements made previously."
Paul has been working two half-time jobs: in the Upper Atmosphere Project at NCAR and as a consultant in the Aeronomy Laboratory of the National Oceanic and Atmospheric Administration. In a week he will leave for Grenoble, France, to talk about his stratospheric modeling work at the conference of the International Union of Geodesy and Geophysics.
Paul was born in Amsterdam. To his first language, Dutch, he quickly added German, Swedish, English, and French. But instead of going into languages as his

teachers advised, he finished high school with a major in mathematics and physics, and after military service and a number of stray jobs, he went to the University of Stockholm Institute of Meteorology, where he remained from 1959 to 1973. He ob- tained his doctorate there in 1968; his dissertation demonstrated the unlikelihood of the then-popular theory that ozone reduction was accomplished by hydroxyl radi- cals. From 1969 to 1971 he was a postdoctoral visitor supported by the European Space Research Organization at the Clarendon Laboratory of Oxford University. While there, he published a paper on the effects of nitric oxide on the ozone layer. "At that time," he says, "I had no idea that supersonic transports--SSTs--might have any effect."
Originally, Paul says, he had intended to go into the field of astronomy. But after getting a job as a programmer at the Institute of Meteorology of the Univer- sity of Stockholm, he decided to switch to meteorology. His undergraduate degree was in mathematical statistics and meteorology, and most of his graduate studies were in dynamics. "I don't have a degree in chemistry," he points out, "like so many others whose field is stratospheric photochemistry. But I had to apply knowl- edge gathered by laboratory photochemists to the workings of the atmosphere. Un- til a few years ago, a very interesting aspect of this task consisted of reading the photochemical literature and interpreting the results--reaction rates weren't listed in cookbooks then; they were often buried in old papers. You had to dig out the information. A few years ago, only a handful of people were active in this field. Now almost every month brings new people in. Many of these may leave the field when the money runs out--but good people are always needed."
He enjoyed giving a seminar during the Advanced Study Program/UAP summer col- loquium and found some interest in his field on the part of the colloquium students. "Many things can be done at NCAR that can't be done in the university setting," he says, "but a large institution is also subject to the danger of overplanning, of becoming occupied too much with the goals of a particular program. In a field like this, there is a lot of pressure to concentrate on the immediate tasks and to lose sight of the broad scientific questions that lead toward the future. I have a feeling that we are still far from understanding the natural processes in the strat- osphere and their coupling to processes in other regions of the atmosphere and in the biosphere. The aim of my work is to gain a little more insight into these
problems, to push my field of science a little further toward the truth."
William Holland
"It's fascinating to contemplate the large-scale phenomena of the ocean--it's
something like being an astronomer looking out at the heavens. The ocean is beauti-
ful from the esthetic point of view, and this comes through when we go back to the
sea and get in touch with what's happening on the research ships," says William
Holland, leader of the Oceanography Project. "As theoreticians, we oceanographers have to keep going back to the sea. It's easy to work in isolation, and it's parti-
cularly important for oceanographers in the middle of the Rocky Mountains to make
observations from shipboard so that we can be sure we're on the right path."(con tinued)

Bill spent a great deal of time at sea during his years as a graduate stu- dent, and "learned an appreciation of the
sea-going aspect of science." He majored in physics at the University of Califor- nia at Los Angeles (UCLA), graduating in 1960, and then spent a summer in the Geo- physical Fluid Dynamics Program at the Woods Hole Oceanographic Institution. From there Bill went to the Department of Meteorology at the Massachusetts Insti- tute of Technology as a Ford Foundation Fellow in oceanography. From 1961 to 1966 he was a graduate student at the Scripps Institution of Oceanography in San Diego.
Bill has childhood memories of Scripps, where his parents often took him to see the exhibits. "It certainly has
Sthe charm, even today, that I remember from childhood." The decision to go into oceanography was made when he was gradu- ated from UCLA and "took a hard look at what I wanted to do. I had a meteorolo- gist friend at UCLA, so a natural link was made there between oceanography and meteorology." Bill was an NSF Fellow in the Department of Applied Mathematics at Cambridge University in England during the year 1966-67 and went on to the Geo- physical Fluid Dynamics Laboratory in Princeton. From 1969 to 1974 he was also a visiting lecturer at Princeton, teaching courses in the Geophysical Fluid Dynamics Program. He came to NCAR in the summer of 1972 as a participant in the Mid-Ocean Dynamics Experiment (MODE) Theoretical Workshop and joined the NCAR scientific staff in 1974 as leader of the Oceanography Project.
Bill's commitment to field research at sea has been realized in his participa- tion in a number of field projects: in the International Indian Ocean Expedition (IIOE) in summer of 1962 to examine equatorial currents in the Indian Ocean during the southwest monsoon; in IIOE in summer of 1964 to measure the time-dependent development of the Somali Current; and in MODE in summer of 1973. Bill's present research is focused on problems of ocean modeling, which include transient motions, mid-ocean eddies, baroclinic instability in the Gulf Stream, tracer distributions and their relationships to the general ocean circulation, wind and thermohaline- driven ocean circulation, effects of bottom topography, energetics, equatorial dy- namics, effects of seasonal fluctuations on the oceanic general circulation, and heat flux by ocean currents.
Bill sees the past decade as "a fantastically exciting one for oceanographers. Research has taken the form of a broad view of ocean circulation with large-scale projects that have produced fundamentally new information about the ocean. Even
NCAR Staff Notes 8/15/75 Page 4
in my short professional career, knowledge about the ocean has doubled and re- doubled. It's been a time for the flowering of knowledge." Bill says that in the next two to four years there is a clear set of theoretical and observational prob- lems to be solved. "The oceanography group at NCAR will be deeply involved in both the scientific and the human aspects of international programs such as POLYMODE, an effort to comprehensively measure the mesoscale eddy field in the North Atlantic. A numerical model of what we expect to find in POLYMODE has been worked out. We are trying to fine-tune the models to really look at details and to get a compre- hensive picture of the way the dynamics hang together." An intensive field year of POLYMODE in 1977 will be preceded by smaller field experiments at sea. POLYMODE is expected to produce quantities of new information about the ocean, along with other programs aimed at understanding ocean dynamics.
"Oceanography is a truly international science," Bill says. "It's important to people of the whole world, encouraging cooperation and understanding between people of many nations."
Richard Somerville
"All major numerical models display about the same level of skill, and I'm interested in learning what limits that skill--what it is about the way we cur- rently do numerical weather prediction that must be changed to extend the range and accuracy of forecasts," says Richard Somerville, leader of the Numerical Weather Prediction Project.
Richard joined NCAR a year ago, but he has been involved with the organiza- tion since its early days. He spent the summer of 1964 here working on his doc- torate, which he earned from the New York University (NYU) Department of Meteorology and Oceanography in 1966. His thesis was entitled "A Nonlinear Spectral Model of Convection in a Fluid Unevenly Heated from Below." Richard also spent the year 1966-67 here as a postdoctoral fellow in the Advanced Study Program, concentrating on problems in pure geophysical fluid dynamics and thermal convection. "That year at NCAR provided a very stimulating exposure to a wide range of problems on which I subsequently worked," he says.
From Boulder, Richard went to the Woods Hole Oceanographic Institution to parti- cipate in the summer program on geophysical fluid dynamics; his research there was
NCAR Staff Notes 8/15/75 Page 5
in magnetohydrodynamics. He spent the next two years as a National Research Council Postdoctoral Research Associate at. the Geophysical Fluid Dynamics Laboratory in Princeton, working with Frank Lipps on tEnard convection in numerical simulations of rotating and nonrotating fluids. Referring to the many places at which he has done research, Richard quips, "I have been a scientific gypsy."
In 1969, he joined the Courant Institute of Mathematical Sciences (NYU's gradu- ate department of mathematics) and worked with Alexandre Chorin on numerical methods for solving the Navier-Stokes equations. "I had decided to make numerical modeling my specialty," Richard says, "and I wanted to learn more numerical analysis than a meteorological education had provided." While at Courant, Richard spent another summer at Woods Hole, "to get my geophysical batteries recharged."
In 1971 Richard was asked to join the Goddard Institute for Space Studies (GISS) in New York. While continuing convection research as a "hobby," he devoted most of his efforts to supervising the development of a new global general circulation model (GCM). "The resources devoted to the development of that model were so in- tensive that in two years we were able to design, code, debug, analyze, tune, and publish the first major new GCM since the NCAR model was begun in 1965," Richard says. "There was a pressing need for the GISS model for use in meteorological sat- ellite research for GARP." He adds, "I am still collaborating with the GISS group."
* While at GISS, Richard was also an adjunct associate professor at NYU and at Co- lumbia University, teaching mainly dynamic meteorology.
Commenting about his work at NCAR, Richard says, "Most of what the members of the Numerical Weather Prediction Project are doing is leading up to the First GARP Global Experiment (FGGE) in 1978-79, which we hope will provide a significant im- provement in data. But we know ahead of time that better data won't be enough--that our current models have several deficiencies that will have to be corrected. There are just too many things that the NCAR GCM and other current models can't do. When you think of general circulation models it's important to keep in mind that it's the circulation and not the model that is general."
COMET KBM IS SEEN
In Violent Universe, an account of the "new astronomy" of the past decade, Nigel Calder gives comets a curt dismissal. "Comets," he writes, "are nowadays regarded as scrap material left over from the manufacture of the planets, some 4 billion years ago." Mere space junk, compared to the distant yet energetic quasar, the dense and deadly pulsar, or the time-rending black hole.
Yet for the amateur--or for the planetary astronomer seeking answers to some * questions that yet remain about the manufacture of the planets--the eye and the
camera stand ready to deny that comets are a bore. Comets have provided the most spectacular celestial entertainments for centuries. Is a comet just a large, dirty snowball? The trained observer knows it to be so--but inwardly feels it must be called a large, dirty, and gZorious snowball.

NCAR Staff Notes 8/15/75 Page 6
Bright comets appear unexpectedly, and recent years have seen a number of new discoveries. Comet Kobayashi-Berger-Milon (KBM), seen opposite, is designated 1975h, which means it is the eighth new comet discovered this year. Like other comets, its nucleus is a small, thickly packed ball of frozen gases and dust. The coma--the cloudlike halo around the nucleus--begins to form under the influence of solar radiation as the comet speeds toward the sun. Classic comets develop two tails; one, made up of dust, is curved along the orbital path; the other is a plasma of ions and electrons blown directly away from the sun in a straight path by the solar wind.
Comets are usually divided into long-period comets, taking longer than 200 years to go around the sun, and short-period comets. The orbits of long-period comets are extremely eccentric; those of short-period comets are less so. Comets have relatively short lifetimes because of the great changes wrought in them by their brushes with the sun and because of the influences of the larger planetary masses that they pass on their way through the solar system. The meteor showers, such as the Perseids through which we have just passed, are thought to be the rem- nants of cometary disintegration.
The pictures opposite come from several sources. The top picture was given to Staff Notes by David Elmore, Donald Woodnan, and Klaus Jockers, who have been tak- ing comet pictures from their Onion Patch Observatory in southern New Mexico. David is the High Altitude Observatory's resident research associate at the Sacramento Peak Observatory (SPO); Donald and Klaus are on the staff of SPO. The 4 min ex- posure was taken with an eight-inch Schmidt camera (f/1.5; focal length 0.2 m) on Kodak 103-aF film at 0534 UT on August 7 (11:34 p.m. MDT on August 6). The field of view is 4.5 X 6.3 degrees. In the original picture, the tail extends to the far edge. (Copyright © Midnight Media, 1975. Used by permission.)
The middle picture was taken by Steven Fahnenstiel at the Orion Observatory in Evergreen, Colorado. It was given to Staff Notes by Gregory Muir of the National Hail Research Experiment, who is director of the Astronomical Research and Educa- tion Association, a Denver-based group of which Fahnenstiel is a member. The pic- ture was taken on 103-aF with a ten-inch Cave reflector (f/5; focal length 50 in.). Exposure time was 10 min, beginning at 0440 UT August 3 (10:40 p.m. MDT August 2). The field of view is 1.3 degrees square. The "butterfly" pattern of the background stars is caused by the manual tracking of the telescope on the comet.
The bottom picture was given to Staff Notes by Gary Emerson, an astronomer at the Laboratory for Atmospheric and Space Physics at the University of Colorado, who is studying the comet with a team under Charles Lillie. The photo was taken through the 24-inch telescope at the Mt. Evans Observatory of the University of Denver from 0935 to 1000 UT July 19 (3:35 to 4:00 a.m. MDTX). The comet was then closest to the earth (38.6 million kjn). The stars in the background are trailed due to the telescope tracking on the comet.
(The orientation of the comet's tail in the pictures differs because the frames chosen by the observers differed. )

ITAMAR HALEVY TO SPEAK IN SOLAR-WEATHER SERIES
Itamar Halevy will give a solar-weather seminar entitled "On the Nature of a
Certain Sun Weather Correlation" next week at the Mesa Lab. The seminar will be held on Tuesday, August 19, at 3:00 p.m. in the Main Seminar Room.
Halevy, who comes from Israel, is a graduate student in mathematics at the Uni- versity of Toronto. He is spending the summer at NCAR, attending the Upper Atmo- sphere Project/Advanced Study Program summer colloquium. He is the co-author, with Colin Hines, of an article soon to be published, which inquires into some work done by Wilcox et al. showing that the vorticity pattern in the upper troposphere re- sponds to the passing by the earth of sector boundaries in the solar-interplanetary magnetic field. Hines and Halevy have subjected this analysis to many statistical tests, using independent data, and reported on the results in May at a NOAA seminar. For further information please call Walter Orr Roberts or Roger Olson at ext. 379.
