Isimo Sezulu Esingajwayelekile ENyakatho naseNingizimu China

Kungani kunemvula enamandla yakamuva eningizimu kanye nezinga lokushisa eliphezulu enyakatho?

Muva nje, amazinga okushisa aphezulu aqhubeka nokukhula enyakatho, futhi imvula enamandla iqhubekile eningizimu. Pho, kungani eningizimu iqhubeka nokuba nemvula enkulu, kuyilapho inyakatho ingahlehli? Umphakathi kufanele usabele kanjani?

Iziteshi zesimo sezulu zikazwelonke ezingama-42 eHebei, eShandong naseTianjin sezifinyelele embundwini wokushisa okwedlulele kusukela ngoJuni 9, futhi izinga lokushisa eliphakeme lansuku zonke leziteshi zezulu zezwe ezingama-86 lidlule ku-40 ° C, okuthinta indawo engaba amakhilomitha-skwele angama-500,000 kanye nenani labantu. kubantu ababalelwa ezigidini ezingama-290, ngokusho kweNational Meteorological Center.

Kungani izinga lokushisa eliphezulu lakamuva eNyakatho liye lashuba kangaka?

UFu Guolan, umbikezeli omkhulu weNational Meteorological Center, uthe muva nje iNyakatho yeChina, iHuanghuai nezinye izindawo zingaphansi kokulawulwa yisimo sezulu esinengcindezi ephezulu, isibhakabhaka asinamafu kancane, imisebe yesibhakabhaka ecwebile kanye nezinga lokushisa elicwilayo likhuthaza ngokuhlanganyela ukuthuthukiswa kwezinga eliphezulu. lokushisa sezulu. Eqinisweni, akukhona nje kuphela ukuthi ukunyuka kwezinga lokushisa kwakamuva kusobala, kuleli hlobo, isimo sezulu saseShayina esiphezulu sokushisa sivele ngaphambi kwesikhathi, lilonke, inqubo yesimo sezulu sokushisa okuphezulu izovela kaningi.

Ingabe isimo sezulu esishisayo sizoba yinjwayelo?

Ngomjikelezo wamanje wesimo sezulu esiphezulu sokushisa eNyakatho ye-China Huanghuai nakwezinye izindawo, abanye abasebenzisi benethiwekhi bazokhathazeka ngokuthi isimo sezulu esinjalo sokushisa sizokhula sibe yisimo esivamile? U-Zheng Zhihai, umbikezeli omkhulu we-National Climate Center, wethule ukuthi ngaphansi kwesizinda sokufudumala kwembulunga yonke, izinga lokushisa eliphezulu lase-China ngokuvamile libonisa isici sedethi yokuqala yokuqala, izinsuku zokushisa eziphakeme kakhulu kanye nokuqina okuqinile. Kulindeleke ukuthi izinga lokushisa ezindaweni eziningi zaseShayina kuleli hlobo liphakeme kunalelo enkathini efanayo yonyaka, futhi nenani lezinsuku zokushisa okuphezulu nalo lingaphezulu. Ikakhulukazi eNyakatho neChina, eMpumalanga China, e-Central China, eNingizimu ye-China nase-Xinjiang, inani lezinsuku zokushisa okuphezulu lingaphezu kwenkathi efanayo yonyaka. Lo nyaka in the El Nino ukubola kwalo nyaka, i-Western Pacific subtropical high unamandla kakhulu, ngokuvamile elawula indawo kuyoba othambekele eziphikelelayo izinga lokushisa eliphezulu, ngakho lo nyaka izinga lokushisa eliphezulu kungase kube sína. Kodwa-ke, izinga lokushisa layo eliphakeme lizoba nezici zesiteji ezisobala, okungukuthi, ngoJuni, ikakhulukazi izinga lokushisa eliphezulu eNyakatho yeChina kanye nendawo yaseHuanghuai, ngakho ngemva kwehlobo, izinga lokushisa eliphezulu lizophendukela eningizimu.

Yiziphi izici zalo mzuliswano wemvula enkulu?

Uma kuqhathaniswa nezinga lokushisa eliphezulu enyakatho, imvula enamandla isavame ukuna eningizimu. Kusukela ngoJuni 13 kuya ku-15, umjikelezo omusha wemvula enamandla uzothinta eningizimu.

Ngenxa yokuna kwemvula enamandla ezindaweni eziningi esifundeni esiseningizimu yalo mzuliswano, uYang Shonan, umbikezeli omkhulu weCentral Meteorological Observatory, uthe isikhathi esiqine kakhulu salo mzuliswano wemvula sibonakale ngobusuku bangomhla ziyi-13 kuya osukwini lwenyanga. Ngomhla we-15, imvula enqwabelene yenqubo ifinyelele ku-40 mm kuya ku-80 mm, futhi ezinye izindawo zeqa ku-100 mm, lapho imvula enqwabelanayo yenkaba nenyakatho ye-Guangxi kanye nokuhlangana kwezifundazwe i-Zhejiang, Fujian kanye ne-Jiangxi yafinyelela ku-250 mm. Ngisho nangaphezu kwamamilimitha angu-400.

Imvula enkulu izoqhubeka kuze kube nini?

U-Yang Shonan wethule ukuthi kusukela ngo-June 16 kuya ku-18, i-Jiangnan, entshonalanga ye-South China, i-Guizhou, i-Southern Sichuan nezinye izindawo zizoba nemvula enkulu kuya kwenkulu, imvula enkulu yendawo, kanye nokuhambisana nokuduma kwezulu kanye neziphepho zendawo.

Kusukela ngomhlaka-19 kuya ku-21, yonke ingxenye esempumalanga yebhande lemvula izoyiswa enyakatho eJianghuai ezindaweni eziphakathi nendawo eziphansi zoMfula iYangtze, iJianghuai, enyakatho yeJiangnan, entshonalanga yeSouth China, empumalanga yeNingizimu-ntshonalanga nezinye izindawo. ibe nemvula emaphakathi ukuya kwenamandla, imvula yendawo noma isiphepho sezulu esinamandla.

Ngesikhathi esifanayo, esikhathini esizayo, izifunda zaseHuang-Huai-hai nezisenyakatho zizoqhubeka nokuba nezinga lokushisa eliphezulu nemvula encane, futhi isomiso singase sithuthuke.

Lapho ubhekene nokushisa okuphezulu kanye nesimo sezulu semvula enamandla, indlela yokubhekana nayo?

Ngenxa yesimo sezulu esisanda kubanda kakhulu sokushisa, ochwepheshe basikisela ukuthi iminyango efanele yenze umsebenzi omuhle wokuvikela nokuvikela impilo yesifo sokushisa, ikakhulukazi kubantu asebekhulile abahlala bodwa, iziguli ezinezifo ezingapheli zesikhathi eside, imindeni ehola kancane enokupholisa okunganele. izinsiza kanye nabasebenzi bangaphandle. Ngesikhathi esifanayo, qinisa ukuthunyelwa kwesayensi, uqinisekise ugesi empilweni nokukhiqiza, futhi uqinisekise amanzi okuphuza kanye namanzi okukhiqiza abantu nezilwane.

Ukwengeza, emzuliswaneni omusha wemvula enkulu eningizimu, indawo enemvula kanye nenkathi yangaphambilini idlula kakhulu, futhi ochwepheshe baxwayisa ngokuthi imvula eqhubekayo ingase ibangele izinhlekelele zesibili.
