Malo: Melbourne, Australia — Pakupita patsogolo kwakukulu pa ulimi wolondola, alimi aku Australia akuchulukirachulukira akugwiritsa ntchito zida zoyezera mvula kuti awonjezere njira zawo zoyendetsera madzi ndikukweza zokolola pakati pa kusintha kwa nyengo.
Mwachikhalidwe, zida zoyezera mvula zakhala ukadaulo wogwiritsidwa ntchito kwambiri poyesa mvula, koma kusintha kwaposachedwa kwa ukadaulo wa radar kumalola kuti pakhale deta yolondola komanso yanthawi yake ya mvula. Zida zatsopano zoyezera mvula za radar zimagwiritsa ntchito njira za Doppler radar kuti zizindikire chinyezi ndi mawonekedwe a mvula m'dera lalikulu. Ukadaulo uwu ukhoza kupereka deta yeniyeni yokhudza kuchuluka kwa mvula ndi kufalikira kwake, zomwe zimathandiza alimi kupanga zisankho zolondola pankhani yothirira, feteleza, ndi kusamalira tizilombo.
"Chifukwa cha kusintha kwa nyengo komanso nyengo yosasinthasintha, kuthekera kopeza deta yolondola ya mvula nthawi yeniyeni ndikofunikira kwambiri pa ulimi wokhazikika," adatero Dr. Lisa Wang, katswiri wa zanyengo komanso katswiri waukadaulo waulimi ku University of Queensland. "Ma radar rain gauge amapereka chidziwitso chokwanira chomwe chimathandiza alimi kugwiritsa ntchito bwino madzi, kuchepetsa kuwononga, komanso kukulitsa thanzi la mbewu."
Kulondola Kwambiri kwa Deta ndi Kuzindikira Kwapafupi
Chimodzi mwa ubwino waukulu wa radar rain gauge kuposa njira zachikhalidwe ndi kuthekera kwawo kupereka chidziwitso chapafupi. Rain gauge yachizolowezi imakhala ndi miyeso ya mfundo ndipo imatha kuphonya mosavuta kusiyana kwakukulu pa mtunda waung'ono. Mosiyana ndi zimenezi, ukadaulo wa radar ukhoza kujambula deta ya mvula m'madera akuluakulu ndikupanga mamapu atsatanetsatane a mvula, zomwe zimathandiza alimi kuwona kuchuluka kwa mvula komwe kunagwa komanso nthawi yomwe inagwa.
Mwachitsanzo, alimi ku Murray-Darling Basin, limodzi mwa madera ofunikira kwambiri a ulimi ku Australia, anena kuti asintha kwambiri njira zawo zoyendetsera madzi kuyambira pomwe adayika ma radar rain gauge mu ntchito zawo. Pogwiritsa ntchito ukadaulo uwu, alimi amatha kusintha nthawi yothirira kutengera zomwe zachitika posachedwa pa mvula, zomwe zimapangitsa kuti pakhale njira zabwino zosungira madzi komanso kugwiritsa ntchito bwino madzi.
Phunziro la Chitsanzo: Kusamalira Feteleza ndi Zokolola za M'munda
Kugwiritsa ntchito zida zoyezera mvula za radar kwathandizanso pakuwongolera momwe feteleza amagwiritsidwira ntchito. Alimi tsopano amatha kudziwa nthawi yomwe feteleza amagwiritsidwira ntchito kutengera momwe mvula imachitikira, kuonetsetsa kuti michere imayamwa bwino ndi mbewu m'malo mosokedwa. Kulondola kumeneku sikuti kumawonjezera zokolola za mbewu zokha komanso kumachepetsa kuwonongeka kwa chilengedwe kwa feteleza wothira m'madzi apafupi.
John Carter, mlimi wa mpunga wochokera ku New South Wales, anafotokoza zomwe adakumana nazo: "Kuyambira pamene tinayamba kugwiritsa ntchito zida zoyezera mvula za radar, taona kusiyana kwakukulu pa zokolola zathu za mpunga. Timatha kugwiritsa ntchito feteleza mvula isanayambe, zomwe zikutanthauza kuti mbewu zathu zikupeza michere yomwe zimafunikira nthawi yomwe zimafunikira. Ndi kusintha kwakukulu momwe timayendetsera zinthu zathu."
Mavuto ndi Ziyembekezo Zamtsogolo
Ngakhale ubwino wa radar rain gauges umadziwika kwambiri, pali zovuta pakugwiritsa ntchito njira zambiri, kuphatikizapo mtengo wa zida komanso kufunika kwa alimi kuti adziwe bwino za ukadaulowu. Komabe, akatswiri amakampani akuyembekeza kuti pamene ukadaulowu ukupezeka mosavuta komanso wotsika mtengo, kuphatikiza kwake muulimi waku Australia kudzapitirira kukula.
Boma la Australia likuthandizanso kusinthaku, poika ndalama mu kafukufuku wa zaulimi ndi mapulogalamu opititsa patsogolo chitukuko omwe amalimbikitsa ukadaulo wamakono kuti ulimbikitse ulimi kupirira kusintha kwa nyengo. Cholinga cha izi ndikuwonetsetsa kuti alimi azitha kugwiritsa ntchito ukadaulo waposachedwa kuti asunge zokolola komanso kusunga chuma.
“Pamene tikukumana ndi mavuto omwe amabwera chifukwa cha kusintha kwa nyengo, ndikofunikira kuti tigwiritse ntchito ukadaulo wothandizira ulimi wokhazikika,” anatero Nduna ya Zaulimi, Senator Murray Watt. “Ma radar rain gauge ndi gawo lofunika kwambiri pankhaniyi, kupatsa alimi deta yomwe akufunikira kuti apange zisankho zolondola komanso kusintha malinga ndi kusintha kwa nyengo.”
Mapeto
Kuphatikizidwa kwa ma radar rain gauge mu ulimi wa ku Australia ndi sitepe yofunika kwambiri yopita ku njira zokhazikika komanso zogwira mtima zaulimi. Pamene alimi ambiri akuyamba kugwiritsa ntchito ukadaulo watsopanowu, uli ndi kuthekera kosintha kasamalidwe ka madzi, kukonza zokolola, ndikuwonjezera mphamvu ya gawo laulimi motsutsana ndi nyengo yosayembekezereka. Ndi kupita patsogolo kosalekeza ndi chithandizo kuchokera ku boma komanso gulu laulimi, tsogolo la ulimi ku Australia likuwoneka loyendetsedwa ndi deta komanso lothandiza kwambiri kuposa kale lonse.
