Kubekho ukwanda okukhulu kwemvula ngexesha lokuqala kwemvula yasempuma-mpuma phakathi kowama-2011-2020 kwaye inani lezehlo zemvula enkulu nalo linyukile ngexesha lokuqala kwemvula, itsho njalo uphando olwenziwe ziingcali zemozulu eziphezulu zeSebe leMeteorological laseIndiya.
Kolu phononongo, kukhethwe izikhululo ezili-16 ezikunxweme oluphakathi konxweme olusemazantsi e-Andhra Pradesh, emantla, embindini nasezantsi eTamil Nadu. Ezinye zezikhululo zemozulu ezikhethiweyo yiNellore, iSulurpet, iChennai, iNungambakkam, iNagapattinam kunye neKanniyakumari.
Olu phononongo luphawule ukuba imvula yemihla ngemihla inyuke phakathi kwe-10 mm kunye ne-33 mm ekufikeni kwemvula enkulu ngo-Okthobha phakathi kowama-2011-2020. Imvula yemihla ngemihla ngexesha elinjalo kwiminyaka engamashumi adlulileyo yayidla ngokuba phakathi kwe-1 mm kunye ne-4 mm.
Kuhlalutyo lwayo malunga nokuxhaphaka kwemvula enkulu ukuya kwenkulu kakhulu kulo mmandla, kutyhilwe ukuba kubekho iintsuku ezingama-429 zemvula enkulu kwizikhululo zemozulu ezili-16 ngexesha lemvula enkulu yasempuma-mpuma kule minyaka ilishumi idlulileyo.
UMnu. Raj, omnye wababhali bolu phononongo, uthe inani leemvula ezinkulu liye leentsuku ezingama-91 kwiveki yokuqala ukusukela oko kwaqala imvula enkulu. Amathuba emvula enkulu kunxweme lolwandle anyuke ngokuphindwe ka-19 ngexesha lesigaba sokubekwa kwemvula enkulu xa kuthelekiswa nesigaba sangaphambi kokuqala. Nangona kunjalo, ezo ziganeko zemvula enkulu azixhaphakanga emva kokuba imvula iphelile.
Olu phononongo luthi nangona umhla wokuqala nowokurhoxa wawungo-Okthobha 23, umhla wokurhoxa wawungoDisemba 31 kule minyaka ilishumi idlulileyo. Ezi zazisemva kweentsuku ezintathu nezine ngokulandelelana kunemihla yexesha elide.
Imvula yahlala ixesha elide kunxweme olusemazantsi eTamil Nadu kude kube nguJanuwari 5.
Olu phononongo lusebenzise indlela ye-superposed epoch ukubonisa ukwanda okukhulu kunye nokwehla kwemvula emva kokuqala nokurhoxa kwayo kwiminyaka elishumi. Yayisekelwe kwidatha yemvula yemihla ngemihla phakathi kukaSeptemba noFebruwari efunyenwe kwiNational Data Centre, IMD, ePune.
UMnu. Raj uqaphele ukuba olu phononongo lulandelelanisa nezifundo zangaphambili ezazijolise ekuveliseni idatha yembali malunga nokuqala kwemvula kunye nemihla yokurhoxa kwayo kwiminyaka eli-140 ukusukela ngo-1871. Iindawo ezifana neChennai ziphule iirekhodi ezininzi zemvula enkulu kwiminyaka yakutshanje kwaye umndilili wemvula yonyaka wesixeko unyukile kwiminyaka yakutshanje.
Sisandula ukuphuhlisa igeyiji yemvula encinci engangeni mvuthuluka efanelekileyo kwiindlela ezahlukeneyo zokujonga okusingqongileyo, wamkelekile ukundwendwela.
Igeyiji yemvula eva ukuhla
