Kuyambira pachiyambi, maloto athu amatipangitsa kukhala aludzu kwambiri kuti tipeze zozizwitsa zonse ndipo ambiri a iwo akuyendabe nafe munthawi yapitayi pomwe ena adasochedwa modabwitsa ndipo sanapezekenso.
Pano, tikukuwuzani nkhani ina yozizwitsa yopangidwa mwaluso kwambiri kuyambira zaka za m'ma 1930 ndi pambuyo pake, yozikidwa ndi wasayansi waku Argentina wotchedwa Juan Baigorri Velar ndi zomwe adapeza - Chipangizo Choyambitsa Mvula - chimene chatayika kwamuyaya. Akuti kachipangizoka kamatha kulamulira nyengo pochita mvula nthawi iliyonse kapena kulikonse komwe angafune.
Wasayansi wosaneneka Juan Baigorri Velar anali wophunzira waukadaulo ndipo adaphunzira ku National College ya Buenos Aires. Pambuyo pake, adapita ku Italy kukachita maphunziro apadera ku Geophysics ku University of Melan. Poyamba anali kugwira ntchito yoyesa magetsi padziko lapansi.
Mu 1926, pantchito yake, pomwe anali kuchita zina zoyeserera zake, adadabwa kwambiri kuwona kuti chida chake chidapangitsa mvula zingapo zomwe zidabalalika mkati mwa nyumba yake ku Buenos Aires. Ubongo wake wabwana nthawi yomweyo unayamba kuganizira za tsogolo lawo lakutali chifukwa zitha kukhala zoyambitsa zomwe zikadasintha dziko lapansi komanso mtengo wamoyo wake wamunthu. Kuyambira pamenepo, anali maloto ake - kupeza ukadaulo womwe ungathe kuyendetsa bwino mvula.
Pambuyo pazaka zingapo izi, maloto a Baigorri a Chipangizo Choyambitsa Mvula adakwaniritsidwa pomaliza, ndipo adayamba kugwiritsa ntchito kupanga mvula mdera lalikulu lomwe lakhudzidwa ndi chilala ku Argentina. Posakhalitsa, adatchuka mdziko lonse lapansi chifukwa chopeza zozizwitsa, ndipo anthu amayamba kumutcha "Lord of the Rain" chifukwa chobweretsa mvula kumadera omwe anakhudzidwa ndi chilala komwe mvula idasiya kugwa kwa miyezi ingapo ngakhale angapo zaka m'malo ena.
Malinga ndi nkhani zina, ku Santiago, makina odabwitsa a Rainmaking a Baigorri adapha gawo lachilala lomwe linali kuchitika miyezi pafupifupi khumi ndi isanu ndi umodzi yapitayo. Chimodzi mwazolemba za Dr. Pio Montenegro chikusonyeza kuti chipangizochi cha Baigorri chidapanga mvula yokwana mainchesi 2.36 kumeneko m'maola awiri okha patadutsa zaka zitatu osagwa chonchi.
"Lord of the Rain" adalinso ndi dzina loti "Wizard of Villa Luro" kuchokera kwa okayikira komanso osakhulupirira kuphatikiza director of the meteorological service, Alfred G. Galmarini yemwe adatsutsa Baigorri kuti abweretse mphepo yamkuntho pa 2 June 1939. Komabe , Baigorri adavomereza zovutazo ndipo molimba mtima adatumiza chovala chamvula ku Galmarini ndi kakalata koti, "kagwiritsidwe ntchito pa 2 Juni."
Monga mawu a Baigorri, kudagwa mvula nthawi yomweyo, ndikuchotsa kukayika konse pazinthu zosangalatsa za Baigorri - "The Rainmaking Machine". Pambuyo pake, ku Carhue, Baigorri akubweretsanso Michigan ngati dziwe lakale nthawi yayitali. Mu 1951, Baigorri adati adatulutsanso mvula mainchesi 1.2 kwa mphindi zochepa kumidzi yakumidzi ya San Juan patadutsa zaka zisanu ndi zitatu zotsatizana zopanda mvula.
Ngakhale Baigorri sanawululepo magwiridwe antchito ake ndi makina ake apamwamba kwambiri a Rain Making Machine, anthu ambiri amati panali chida chake A ndi dera B muchida chake chazizizi pang'ono ndi mvula yambiri.
Ndi zochitika zodabwitsazi, titha kuganiza kuti Chipangizo Choyambitsa Mvula chinali choti apange Baigorri kutchuka ndipo chimapeza malo ofunikira pamndandanda wazotsogola kwambiri padziko lapansi, koma kwenikweni, palibe amene amadziwa dzina lake m'masiku ano. Ngakhale, a Baigorri akuti adalandira zokopa zingapo zakunja kuti agule zomwe adapeza, koma adakana, akuumiriza kuti idamangidwira kupindulitsa dziko lake la Argentina lokha.
Baigorri Velar adamwalira mu 1972 ali ndi zaka 81 ndipo zaka zomalizira za moyo wake zidathera pamavuto ake komanso umphawi. Palibe amene amadziwa zomwe zidachitika ndi chida chake chodabwitsachi, koma akuti patsiku lomwe adayikidwa, kudagwa chimvula chambiri.
Tsoka ilo, mpaka pano sitikudziwa kuti makina ake amatsenga a Rainmaking adagwiradi ntchito bwanji ndipo ili kuti tsopano. Pambuyo pa zonsezi, kupangidwa ndi machitidwe a Baigorri Velar akhala akuwoneka okayikira. Anthu ambiri okayikira anena kuti nyengo zomwe amati zinapanga sizinangochitika mwangozi.
