NotesNational Center for Atmospheric Research

More than one hundred scientists, technicians,engineers, and graduate students from universities andinstitutions all over the nation-including several dozenNCAR staff-are in central Florida through 18 Augustfor the Convection and Precipitation/ElectrificationExperiment (CaPE). NCAR joins the National Oceanicand Atmospheric Administration (NOAA), the NationalAeronautics and Space Administration (NASA), the U.S.Air Force, and the Federal Aviation Adminstration(FAA) for CaPE. The common goal: tracking Florida'sfrequent thunderstorms to study their electric fields,evolution, and rainfall.

NCAR scientists and technicians at CaPE are fromthe Atmospheric Technology Division (ATD), theMesoscale and Microscale Meteorology Division(MMM), and the Research Applications Program (RAP).CaPE's operation directors are Brant Foote (RAP/MMM), Jim Wilson (ATD/RAP), and Roger Wakimoto(University of California, Los Angeles).

The humid, near-tropical environment of centralFlorida has the nation's highest frequency of days withthunderstorms. Stationed at the Kennedy Space Centerduring the peak of Florida's storm season, the scientistscan expect thunder on most days. That will help them fine-tune their ability to (Photo by Bob Bumpas.)predict thunderstorms a few hours in advance, one of CaPE's main goals. CaPEwill also cooperate with other FAA and NASA field programs, sharing me-soscale observation networks. Also, one of the first of the National WeatherService's upgraded Doppler radars is being placed at Melbourne, Florida. In This IssueStriking Research

The FAA will use information gained from the experiment to help develop CaPEtechniques to forecast the onset of thunderstorms and windshifts as they impact MECCA Dedicationterminal and flight operations. NASA and the air force will benefit from NASA at RAPimproved short-term forecasts as well, especially of lightning, a major hazard in Delphi Questionthe area. Between 1 June and 1 September 1990, lightning struck the Cape AnnouncementsCanaveral/Kennedy Space Center region 14,387 times. In the past two years, Visitors12 out of 16 space shuttle launches at the site have been cancelled or delayed Library Newsdue to lightning concerns. Job Openings

CalendarThe CaPE scientists hope to discover how precipitation growth and charge

transfer lead to electrified clouds and lightning. Evidence from both laboratoryand field studies suggests that colliding ice crystals in thunderstorm clouds arethe primary mechanism of cloud electrification. For instance, heavy rain can fall

Page 2*Staff Notes*25 July 1991

unaccompanied by lightning if iceparticles have yet to form aloft.However, no direct airborne measure-ments have been made during suchstudies.

Using the South Dakota School ofMines' armor-plated T-28 aircraft andNASA's Lear jet, the scientists areflying into the thunderstorms toidentify the clouds' detailed precipita-tion and electrical structures. Inaddition, Doppler radars will defineair motions within and near clouds,and ATD's Surface and SoundingSystems Facility has recruited centralFlorida residents to launch weatherballoons that will measure tempera-ture, humidity, and winds throughthe depth of the troposphere.

Computer modeling is anotherCaPE goal. The scientists willcombine multiple data sources, suchas satellites, radars, and windprofilers, to develop a mesoscaleforecast model. Currently, with onlya handful of regular weather-balloonsoundings over the peninsula, deepconvection generated by the seabreezes is noticed but weak large-scale and mesoscale disturbancesoften sneak in undetected. Puttingdata from multiple sources into theRegional Atmospheric ModelingSystem from Colorado State Univer-sity, researchers hope to make re-gional cumulus convection predict-able 2 to 12 hours in advance.

From Colorado to FloridaCaPE will allow NCAR, NOAA,

and National Weather Service scien-tists to extend to another climatic zonethe work they've been doing topredict thunderstorm initiation,microbursts, and tornadoes atDenver's Stapleton InternationalAirport. Using sensitive Dopplerradars, thermodynamic balloonsoundings, and aircraft measurementsfrom King Airs operated by NCARand the University of Wyoming, themeteorologists are investigating theorigin and structure of local windsystems that lead to the developmentof Florida's thunderstorms. Thescientists believe that, in the absenceof large-scale weather systems, thesesmaller features are needed to kick offthunderstorm development, evenwhen the air mass is hot, humid, andunstable.

Another question to be addressedis why only a few thunderstormsproduce microbursts, even thoughmany storms share the same visualpattern of evolution. Computermodeling results hint that the amountand, especially, the type of precipita-tion will determine the presence andstrength of a microburst. High-resolution data from Doppler radarsand aircraft will test that hypothesis.

Tornadoes that form out ofnonsupercell thunderstorms (stormsthat grow and die without a long-lasting updraft) are being studied bycombining low-level Doppler datawith surface and upper-air observa-tions of temperature, moisture, andwind. Such tornadoes are usuallysmaller and less damaging than thosefrom supercells, but they frequentlyoccur in such disparate areas ascentral Florida and northeast Colo-rado. One study, for instance, hasshown that Orlando has a higheroverall frequency of tornadoes thanOklahoma City. CaPE will examinehow such tornadoes may formthrough the interaction of horizontal

convective rolls and convergenceboundaries within a kilometer of theground.

In CaPE's last research objective,radars are measuring-and aircraftare penetrating"warm" convectiveclouds to determine raindrop size anddistribution. NCAR's CP-2 multi-parameter Doppler radar is compar-ing horizontal and vertical crosssections and other qualities of rain-drops to find the best means ofdetermining rainfall rate. The datawill be used to develop satellitetechniques to measure rainfall overthe world's tropical regions.

The practical benefits to be drawnfrom CaPE are manifold. Under-standing thunderstorms and lightningwill better prepare people againststorm-related damages, injuries, ordeath. Lightning research also willimprove aircraft and space shuttledesign because, in a marginallyelectrified cloud, the vehicles caninitiate discharges that might notoccur naturally. For example, on26 March 1987, the unstaffed Atlas-Centaur 67 launch vehicle triggeredlightning that destroyed it 48 secondsinto flight as it traveled throughcharge-laden clouds and distorted theelectric field. Finally, knowledgegained through CaPE will helpatmospheric scientists more preciselypredict the location, time, and severityof an upcoming storm, benefittingspecific users such as aviators as wellas the general public. *Patti Parisi,Media Relations intern

SCD Dedicates a CRAYDedicated to ClimateModeling

Most research facilities are ecstaticto have one CRAY Y-MPsupercomputer on line. The ScientificComputing Division (SCD) now hastwo. Guests from science and indus-try feted the newest Y-MP at the MesaLab last week as it began its single-minded task of examining globalclimate models.

The dual-processor CRAY Y-MP2D is funded by MECCA, theModel Evaluation Consortium forClimate Assessment. MECCAconsists of UCAR, the Electric PowerResearch Institute (EPRI, a research-and-development arm of U.S. utili-ties), Japan's Central Research Insti-tute of the Electric Power Industry,the Italian Commission for Researchand Development of Nuclear andAlternative Energy Sources, and thegovernment utility Electricit6 deFrance. This group of sponsors,which may grow during MECCA'sprojected life span of three years, isproviding $12.5 million for a series ofnumerical experiments to quantify theuncertainties associated with climateforecasts and to study potentialregional impacts of climate change.As part of UCAR's contribution toMECCA, SCD will provide its fullrange of services for Y-MP2D users:training, troubleshooting, documenta-tion, visualization tools, NCAR'sMass Storage System, and access tothe Internet.

Speakers at the CRAY dedicationon 16 July were UCAR president RickAnthes and Board of Trustees chair-man James Kimpel, NCAR directorBob Serafin, EPRI vice presidentGeorge Hidy, and SCD deputydirector Pete Peterson. After atraditional ribbon cutting in the SCDmachine room, a press conferencefeatured Rick; Peter Mueller, MECCA

Policy Committee chairman; andDoug Young, environmental andenergy staff assistant to U.S. senatorTim Wirth. Also on hand were SusanDamour, district director for U.S.representative David Skaggs; Boulderdeputy mayor Annette Anderson; andBoulder city manager Tim Honey.

Christening the Y-MP2D forMECCA will be four studies evaluat-ing the sensitivity of four elements inthe NCAR community climate model.Two of the studies are by Climate andGlobal Dynamics Division scientists:Dave Williamson (examining gridresolution) and Warren Washington,Jerry Meehl, and Jim Hack (ocean-atmosphere coupling). The others are

by Ann Henderson-Sellers,Macquarie University, Australia(deforestation); and Barry Saltzman,Yale University (carbon dioxide).More than a dozen additional propos-als are under review, and severallarge atmosphere, ocean, and air/ocean coupled models are expected tomake the final cut.

MECCA principals hope to havetheir first results by June 1992 topresent at a United Nations confer-ence on development and the envi-ronment in Rio de Janeiro, Brazil.Once numerical data are in hand,MECCA plans to interpret and assessthe results for policymakers and theprivate sector. *BH

Into the Shear: NASA and RAP Put Warnings to the Test

As part of a two-week check onwind shear sensing technology, theResearch Applications Program ishelping the National Aeronautics andSpace Administration with the crazy-sounding task of guiding a 737-100aircraft directly into microbursts.

The idea, explains RAP scientistKim Elmore, is to compare aircraft-measured wind shear with thatmeasured by ground-based warningsystems. RAP and the MassachusettsInstitute of Technology (MIT) LincolnLaboratory have collaborated onsoftware packages over the past fewyears that use Doppler-radar winddata to find the small regions ofdiverging air that can get aircraft intoserious trouble. Both RAP and MITversions of the algorithms are beingused in the study, which is scheduledto wind up tomorrow.

The NASA plane is tailor-madefor this job. It has an experimentalnose-mounted Doppler radar capable

of looking down a flight path andmeasuring winds ahead of the air-craft. Kim and colleagues at the RAPAviation Weather Development Lab(operations center) are using datafrom Mile High Radar to direct the737 into microbursts. Through theuse of packet radio-an inexpensiveFM-based system familiar to amateurradio hobbyists-data from RAP isbeing sent to NASA workstationsaboard the plane. "We used packetradio in WISP [the Winter Icing andStorms Project] to transmit data fromradiometers and our mobile sound-ings system in the field," says Kim."It's a dirt-cheap device. It's not veryfast, but as long as you can live withthe relatively slow data rate, it is greatfor experiments."

Not all microbursts will do forNASA. Its 737 is restricted to asemicircle about 30 kilometers(20 miles) in radius northeast ofDenver because of Stapleton Interna-tional Airport traffic, the plane's size,

and radar resolution demands. Eventhen, the wind shear has to be withinsafe limits. Guiding that decision isthe "F factor," a mathematical con-struct that includes horizontal windshear, vertical wind velocity, and theplane's forward speed.

"It's something the airframemanufacturers are comfortable withand the Federal Aviation Administra-tion has mandated for on-board sheardetection," says Kim. "The ideabehind NASA's visit is to incorporatethe F factor into warnings as a moreuseful and representative number toindicate a plane's shear-inducedperformance loss." Developed severalyears ago by NASA's Roland Bowles,the F factor can be estimated from theLincoln Lab software and Mile Highradar data. The 737 checks thisnumber by flying parallel to the MileHigh radar beam and measuringwinds remotely (with its nose-mounted radar) and directly (with insitu instruments) as it flies within the

Page 5eStaff Notes*25 July 1991

microbursts. Other wind sensors onboard are being tested, including apassive infrared sensor developed byBoulder's Turbulence PredictionSystems.

Some 50 NASA support personnelare stationed with the 737 at BuckleyAir National Guard Base, its tempo-rary home. Meteorologist FredProctor is the NASA envoy at RAP'soperations center. Along with Kim,software engineers Rick Grubin andBob Barron (the technical lead) haveguided RAP's share of the work.

As of last week, the weatherwasn't cooperating: suitablemicrobursts were few and far be-tween. "It's quite disappointing.Climatologically, the best time formajor microbursts is July, but we'vebeen in an August monsoon patternwith light winds aloft," Kim says."We need some westerlies aloft to getstorms off the mountains." *BH

In the Galleries: Doris Marx Inslee and Ann Marie Gordon

The watercolors of Doris Marx Inslee will be on display in the second-floor gallery of the Mesa Lab from 2 through29 August. In her paintings, Inslee tries to capture the sense of wonder and peace that she experiences on the High Plains.Many of her paintings show plains vistas, but her show will also include floral still lifes.

After graduating from the University of Colorado, Inslee worked as a chemist at the University of Pittsburgh,Harvard Medical School, and the Massachusetts Institute of Technology. She first studied art as a child in Denver with ViAnderson and William Josephs and with Mary Fenner of Boulder. Later she studied with printmaker George Nama ofPittsburgh and Xenia Lucas of the New England Institute of Creative Arts in Boston.

Inslee's work has appeared in dozens of shows, including the Northeast Junior College in Sterling, the PinehurstCountry Club in Denver, the Limon Depot, The Gallery in Longmont, the Aspen Art Museum Fair, the Foothills ArtGallery in Golden, and the Colorado State Fair in Pueblo. She is the owner of the Boston Begonia on West 37th Avenuein Denver.

Anne-Marie Gordon will show her watercolors in the cafeteria from 2 August through 29 September. Gordon wasborn in Australia, the daughter of a sheepshearer and a nurse. In 1979 she studied at the Royal Ontario Museum inCanada, where she became interested in sketching. Later, in Florida, she studied with Jeffery Ryerson, Josette Urso, andElaine Hassellbach. In 1984 she began a bachelor of fine arts degree at the University of South Florida, where she studiedunder art professor Bruce Marsh. Gordon moved to Boulder in 1987.

Gordon's work has appeared locally at the Foothills Gallery and the Solar Energy Research Institute, both in Golden;the Colorado State Fair in Pueblo; Gallery 44 in Boulder; and NCAR.
