Moprofesa oa polytechnic o ikemiselitse ho sebelisa lintlha tsa liteishene tsa boemo ba leholimo ho bolela esale pele hore na matla a letsatsi a tla fumaneha neng

Lintlha tsa boemo ba leholimo li 'nile tsa thusa baprofeta ho bolela esale pele maru, pula le lifefo. Lisa Bozeman oa Purdue Polytechnic Institute o batla ho fetola sena e le hore beng ba lits'ebeletso tsa motlakase le tsa letsatsi ba ka bolela esale pele hore na khanya ea letsatsi e tla hlaha neng le hokae, 'me ka lebaka leo, ba eketse tlhahiso ea matla a letsatsi.
“Hase feela hore na leholimo le leputsoa hakae,” ho boletse Boseman, moprofesa ea thusang ea fumaneng lengolo la hae la Ph.D. boenjiniere ba indasteri. “Hape ke taba ea ho fumana tlhahiso le tšebeliso ea motlakase.”
Bozeman o ntse a batlisisa kamoo data ea boemo ba leholimo e ka kopanngoang le li-data tse ling tse fumanehang phatlalatsa ho ntlafatsa karabelo le katleho ea gridi ea naha ka ho bolela esale pele tlhahiso ea matla a letsatsi ka nepo. Likhamphani tsa litšebeletso tsa motlakase hangata li tobana le phephetso ea ho fihlela tlhoko nakong ea lehlabula le chesang le mariha a batang.
“Hona joale, mehlala e fokolang ea ho bolela esale pele ha letsatsi le ntlafatso e fumaneha ho lits'ebeletso mabapi le tšusumetso ea letsatsi le letsatsi ea matla a letsatsi ho gridi,” ho boletse Bozeman. “Ka ho fumana hore na re ka sebelisa data e teng joang ho lekola tlhahiso ea letsatsi, re tšepa ho thusa gridi. Baetsi ba liqeto ba tsamaiso ba khona ho laola maemo a leholimo a feteletseng le litlhōrō le likhohlo tsa tšebeliso ea matla.”
Mekhatlo ea mmuso, boema-fofane le baphatlalatsi ba litaba ba beha maemo a sepakapaka leihlo ka nako ea sebele. Tlhahisoleseling ea hajoale ea boemo ba leholimo e bokelloa ke batho ka bomong ba sebelisang lisebelisoa tse hokahantsoeng ke Inthanete tse kentsoeng malapeng a bona. Ho phaella moo, lintlha li bokelloa ke lisathelaete tsa NOAA (National Oceanic and Atmospheric Administration) le NASA (National Aeronautics and Space Administration). Lintlha tse tsoang liteisheneng tsena tse fapaneng tsa boemo ba leholimo lia kopanngoa 'me li etsoa hore li fumanehe ho sechaba.
Sehlopha sa lipatlisiso sa Bozeman se ntse se hlahloba litsela tsa ho kopanya tlhahisoleseling ea nako ea sebele le data ea boemo ba leholimo ba nalane ho tsoa ho National Renewable Energy Laboratory (NREL), teko ea mantlha ea naha ea Lefapha la Matla la US lipatlisisong le nts'etsopele ea matla a nchafatsoang le tšebeliso e ntle ea matla. NREL e hlahisa sete ea data e bitsoang Typical Meteorological Year (TMY) e fanang ka boleng ba mahlaseli a letsatsi a hora le likarolo tsa boemo ba leholimo bakeng sa selemo se tloaelehileng. Lintlha tsa TMY NREL li ka sebelisoa ho fumana maemo a tloaelehileng a boemo ba leholimo sebakeng se itseng ka nako e telele.
Ho theha sete ya data ya TMY, NREL e nkile data ya seteishene sa boemo ba lehodimo ho tloha dilemong tse 50 ho isa ho tse 100 tse fetileng, ya e lekanya mme ya fumana kgwedi e haufi le karolelano, ho boletse Boseman. Sepheo sa phuputso ke ho kopanya data ena le data ya hajwale ho tswa diteisheneng tsa boemo ba lehodimo tsa lehae ho pholletsa le naha ho bolela esale pele mocheso le boteng ba mahlaseli a letsatsi dibakeng tse itseng, ho sa tsotelehe hore na dibaka tseo di haufi kapa di hole le mehlodi ya data ya nako ya nnete.
“Re sebelisa tlhahisoleseling ena, re tla bala litšitiso tse ka bang teng ho gridi ho tsoa lits'ebetsong tsa letsatsi tse ka morao ho mithara,” ho boletse Bozeman. “Haeba re ka bolela esale pele tlhahiso ea letsatsi nakong e tlang, re ka thusa lits'ebeletso tsa motlakase ho fumana hore na li tla ba le khaello kapa motlakase o mongata.”
Leha lits'ebeletso tsa motlakase hangata li sebelisa motsoako oa mafura a fossil le a nchafatsoang ho hlahisa motlakase, beng ba matlo le likhoebo tse ling li hlahisa matla a letsatsi kapa a moea sebakeng seo ka mor'a mithara. Leha melao ea ho lekanya ka net e fapana ho ea ka linaha, ka kakaretso e hloka lits'ebeletso tsa motlakase ho reka motlakase o feteletseng o hlahisoang ke liphanele tsa motlakase tsa bareki. Kahoo ha matla a letsatsi a mangata a fumaneha ho gridi, lipatlisiso tsa Bozeman le tsona li ka thusa lits'ebeletso tsa motlakase ho fokotsa tšebeliso ea tsona ea mafura a fossil.
