NATIONAL CENTER FOR ATMOSPHERIC RESEARCH

NORTH GIVES NCAR PRIZE LECTURE

Climate modeling attracted Advanced Study Pro-gram (ASP) visitor Gerald North last year when heread some of the literature and attended ASP sem-inars on climate given by Philip Thompson andStephen Schneider of the Climate Project. His in-terest was further piqued when a review article bySchneider and Robert Dickinson (Climate Project)appeared; it suggested that, mathematically speak-ing, the earth's present climate may rest in a

delicate equilibrium. Jerry's interest resulted intwo publications (Analytical solution to a simpleclimate model with diffusive heat transport,J. Ab'os. Sci. 32, 1301-1307, and Theory of energy-balance climate models, J. Abnos. Sci. 32, 2033-2043, both published in 1975) that together wonNCAR's 1975 Outstanding Publication Award.

On Tuesday, 23 March, Jerry delivered the NCARPrize Lecture, which is given each year by the win-ner of the publication award. He was introduced byNCAR executive director John Firor, who explainedthat Jerry had kindly agreed to come back to NCARafter the conclusion of his ASP visit to delvierthe Prize Lecture. Jerry is an associate professorof physics at the University of Missouri at St.Louis. He graduated from the University of Tennes-see and received his doctorate in theoreticalphysics from the University of Wisconsin at Madison.

Jerry's topic was modeling of the earth's large-scale climate using energy-balance climate models.Before he began, he took a moment to thank thescientists who inspired and assisted him during hisvisit with ASP. He then gave a very brief historyof the earth's climate over the past few millionyears, noting that the major problem for climatolo-gists considering this lengthy epoch was to explainthe ebb and flow of the glacial periods. A numberof explanations have been advanced--continentaldrift, volcanic activity, and changes in the possi-bly inconstant "solar constant" are popular ones--but, Jerry said, "the jury is still out" and noexplanation has received general acceptance. Overshorter historical scales, many more explanationshave been put forward to explain the advance andretreat of the north polar ice cap, including vari-ations in the earth's orbit, volcanic dust in thestratosphere, variations in atmospheric carbon di-oxide, changes in ocean circulation or salinity,and glacial surges in Antarctica.

To test these and other theories, Jerry said,scientists have devised a hierarchy of climatemodels. He noted that these are described in thereview article published by Schneider and Dickinson(Climate modeling, Rev. Geophys. Space Phys. 2,447-493, 1974). They range from "flat earth" one-dimensional models--useful in studying problems ofradiative transfer but unable to represent horizon-tal transports of energy--through zonally averagedmodels and small three-dimensional models to thelarge global circulation models.

The zonally averaged models also average climateparameters annually and allow latitude dependencesof albedo and surface temperature as well as merid-ional transfer of heat. In such models it is pos-sible to allow the snow or ice line (the furthestequatorward extent of the polar ice caps and gla-ciers) to vary dynamically depending on the climatevariables. Small changes in the solar constantintroduced into such models lead to a change inglobal temperature, and this effect is amplified bythe ice-albedo feedback in the model.

Jerry took his audience on a mathematical ramblethrough such a model, in which the equilibrium orstable solutions to the energy-balance equationsare reached by spectral methods--mathematicallyapproximating exact solutions with a rapidly con-vergent sequence of approximations in which eachsuccessive approximation incorporates information

from smaller spatial and temporal scales. He ana-lyzed the stability of the solutions or climatesreached by these methods and found that his modelshared an interesting property with similar models--the stable solutions appear to resemble either thepresent climatic conditions of the earth or a total-ly ice-covered earth. If models of this type bearany resemblance to the conditions in which the realworld revolves, then, Jerry said, world climate isindeed in a delicate balance.

The mathematical approach Jerry took is notnecessarily the approach taken in the usual modelsof the same zonally averaged type, but such modelscan be classified and their interconnections studiedby reference to the spectral method he used.

Jerry concluded his talk with a discussion ofthe next steps for climate modelers interested inthe insights to be gained by using such models.He is currently working with James Coakley of theClimate Project on a model that can represent sea-sonal variations in the global climate. * MM

MANAGEMENT COMMITTEE

DISCUSSES OSO-8 PROPOSAL

A proposal of the High Altitude Observatory(HAO) to assume responsibility for a University ofColorado space experiment met with positive responsefrom the Management Committee at a special meetingTuesday morning (23 March). The university's Lab-oratory for Atmospheric and Space Physics (LASP)has asked HAO to take over responsibility for itsultraviolet spectrometer experiment, which has beenin orbit since last July and is operating in tandemwith a French experiment. The experiment is aboardthe OSO-8 satellite and is funded entirely by NASA.In the first year of operation, valuable data onsolar structure, active regions, and spectra havebeen gathered, but LASP has encountered difficultiesin continuing the mission operation and in embarkingon data analysis. The recommended transfer of NASAfunds to NCAR via NSF would take place on 1 July;the operations control center and all necessarypersonnel would move from LASP to NCAR-acquiredspace on 1 July or as early thereafter as could bearranged.

The Management Committee reviews all proposalsfor non-NSF funding to test them for appropriate-ness to NCAR's mission and to identify possiblehidden impacts on NCAR support elements. The sci-entific merits of the experiment had been endorsedby a review committee (Raymond Roble, Peter Gilman,and William Mankin) and were not discussed by thecommittee.

HAO scientist Dick White told the committee thatthe experiment is valuable to the entire solar re-search community and is consistent with HAO's re-search objectives. He and Grant Athay have beeninvolved in the experiment as scientific co-investigators since its beginning. HAO's proposalrecommends continuing the experiment's data gather-ing for another year, but with reduced intensity,and an immediate beginning on data analysis. Themanagement team would consist of White as projectleader, Elaine Hansen (presently at LASP) as projectmanager and computing support task force leader,Athay as scientific analysis task force leader,and Eric Chipman (presently at LASP) as scientificoperations leader.

Stuart Patterson said that OSO-8's need forabout 100 hours of computer time in the next yearcould be met on a "background" mode; HAO will item-ize its needs for services within the AdministrationDivision, and NCAR will initially negotiate withthe University of Colorado for OSO-8 quarters. *

AND NOW FOR SOMETHING

COMPLETELY DIFFERENT. . .

Last week, Staff Note6 ran a picture ofComet West on the cover. This week, our CometWest picture appears here. This picture wastaken on 13 March shortly before dawn by DonaldWoodman and David Elmore. Don is a staffphotographer/cinematographer at Sacramento PeakObservatory, and David is the NCAR High AltitudeObservatory support scientist stationed at Sac-ramento Peak. The photo was made using aSinar P view camera with an f/4.5 Bausch &Lomb 255 mm lens. The 10-min exposure wasguided at the sidereal rate.

The comet was discovered last November byastronomer R. West of the European SouthernObservatory in Geneva, and it was quite liter-ally the nth comet in a banner year forcomets--its official designation is 1975n(comets are given alphabetic designators asthey are discovered each year). It swungaround the sun on 25 February and was abrighter-than-first-magnitude object duringthe first week of March, easily observable inthe east before dawn. *
