Heerarka baddu oo kor u kacaya heer "baqdin leh" sababtoo ah isbeddelka cimilada iyo xaalufka biyaha dhulka hoostiisa ayaa khatar gelinaya dhaqaalaha xeebaha, saraakiisha ayaa ka digay shalay.
Laba magaalo oo muhiim ah, Shanghai iyo Tianjin, ayaa ka mid ah kuwa wajahaya khatarta ugu weyn, ayuu yiri afhayeenka maamulka badweynta ee gobolka (SOA) Li Haiqing, isagoo soo xiganaya warbixinta kormeerka heerka badda ee wakaaladda ee 2007.
30-kii sano ee la soo dhaafay, xarunta dhaqaalaha ee Shanghai waxay aragtay heerka badda oo kor u kacay 115 mm, ama dhererka kala bar chopstick, ayay tiri warbixintu.
Tianjin, oo ah deked weyn oo qiyaastii laba saacadood u jirta Beijing, ayaa aragtay heerka kor u kaca ilaa 196 mm, oo ku saabsan dhererka qalin cusub.
30-kii sano ee la soo dhaafay, guud ahaan heerka badda ee waddanku waxa uu kor u kacay 90 mm iyada oo celceliska heerkulka baddu uu kor u kacay 0.9C.
Marka la barbardhigo, markii heerka badda adduunka uu kor u kacay 1.7 mm sannad kasta intii u dhaxaysay 1975 iyo 2007, heerka badda Shiinaha ayaa kor u kacay 2.5 mm sannad kasta, SOA ayaa sheegtay.
Tobanka sano ee soo socda, saadaasha SOA, heerka badda ee Shiinaha waxay u badan tahay inuu kordho 32 mm, ama 3.2 mm sannad kasta.
Tani waa markii ugu horeysay ee SOA ay ka warbixiso tirooyinka isugeynta ee heerka badda 30kii sano ee la soo dhaafay. Warbixinta ayaa hadda la sii daayaa sanad walba, halkii ay ahayd saddexdii sano ee la soo dhaafay.
Nidaamka qiimeynta khatarta ah ee saddex-degree ah ayaa ay dejisay SOA si ay ugu wargeliso magaalooyinka xeebaha khataraha ka iman kara, Chen Manchun, oo ah cilmi-baare ka tirsan SOA, ayaa u sheegay Shiinaha Daily.
Heerka badda ee kor u kaca adduunka oo dhan lama beddeli karo, sidaas darteed mas'uuliyiinta magaalada Shiinaha iyo qorshayaasha waa inay qaadaan tillaabooyin ay ula qabsanayaan isbeddelka, ayuu yidhi.
Kulaylka caalamiga ah ayaa ah sababta ugu weyn ee kor u kaca heerarka badda, saraakiisha SOA waxay yiraahdeen, laakiin hoos u dhigista dusha sare ayaa sidoo kale lagu eedeeyaa khatarta fatahaadaha Shanghai iyo Tianjin - sababtoo ah "ka faa'iidaysiga aan kala sooc lahayn ee kheyraadka biyaha dhulka hoostiisa ah" - Chen ayaa sidaas yidhi.
Shanghai ayaa sidoo kale wajaheysa dhibaato dheeraad ah si loo hubiyo in la helo biyo nadiif ah 20 milyan oo qof oo deggan sababo la xiriira faragelinta biyaha badda, ayuu tilmaamay.
Warbixinta heerka badda ayaa sidoo kale muujineysa isku dheelitir la'aan, SOA ayaa sheegtay iyada oo aan sharraxin sababta. Laga soo bilaabo Webiga Yangtze ilaa woqooyiga, magaalooyinku waxay u muuqdaan inay la kulmaan dhibaatooyin ka daran kuwa koonfurta.
Gobollada Liaoning, Shandong iyo Zhejiang waxay arkeen in heerka badda uu kor u kacay ilaa 100 mm, halka gobollada Fujian iyo Guangdong, oo ay ku jiraan agagaarka webiga Pearl Delta iyo Hong Kong, kor u kaca wuxuu ahaa 50-60 mm.
Sidoo kale shalay, SOA waxay soo saartay Warbixinta tayada Deegaanka ee Shiinaha 2007 iyo Shiinaha 2007 Warbixinta Musiibada Badda. Warbixinta tayada deegaanka ayaa muujineysa hoos u dhac weyn oo ku yimid tayada biyaha xeebaha oo ay sababtay wasakhowga ilaha xeebaha.
