Phakathi kwezixhobo zemozulu ezisetyenzisiweyo kwihlabathi liphela kwaye okona kubalulekileyo sikufumana iplaviometer. Igama livela kwiplavio elithetha imvula nakwimitha ebhekisa kwimilinganiselo yayo. Ke ngoko, isilinganisi semvula sisixhobo sokulinganisa imvula. Le gauge yemvula ifakiwe kwi- izikhululo zemozulu kwaye yinto ebonelela ngolwazi olukhulu ukuze wazi zombini imeteorology kunye nemozulu yendawo. Yonke imvula iqokelelwa sesi sixhobo.
Apha ungafumanisa ukuba igeyiji yemvula isebenza njani kunye nokubaluleka kwayo kwimeteorology nakwimozulu.
Yintoni igeyiji yemvula
Esi sisixhobo esisetyenziselwa ukukwazi ukulinganisa imvula ewela kwindawo ngexesha elithile. Ezi datha zemvula ziyarekhodwa kangangokuba zinokusetyenziselwa ukulungisa iphepha ledatha yemozulu yommandla. Ngayo yonke idatha eqokelelweyo, imilinganiselo yemvula yenziwa ngeenyanga, unyaka nonyaka, ukubona indlela imvula ehla ngayo ngokuhamba kwexesha.
Umzekelo, ukuba indawo inobuninzi bemvula ngonyaka obumalunga ne-500 mm, oku kuyaziwa kuba idatha yemvula ibhaliwe iminyaka emininzi. Imilinganiselo yokuqala isusela emva kwiminyaka yoo-1800. Igeyiji yemvula inokuqokelela idatha nakoluphi na uhlobo lwemvula enje imvula, isichotho, nieve, imvula okanye ukunkcenkceshela. Inkqubo ye- Inkungu okanye umbethe awunakulinganisa kuba kuphela kukuxinana kwamanzi.
Eyona nto iluncedo ngamandla Linganisa imozulu yemozulu yendawo ukuze ikwazi ukuseka idatha eyahlukeneyo.
Umvelaphi
Nangona ibonakala ngathi yeyangoku, imilinganiselo yemvula Yirekhodwe ukususela nge-500 BC. AmaGrike ayengabokuqala ukulinganisa imvula. Emva kwexesha, eIndiya, babesele benengqokelela yemvula yokwenene. Babeke izikhongozeli kunye nezikhongozeli ukuze bakwazi ukubamba amanzi emvula kwaye bakwazi ukulinganisa. Kwezi meko, umlinganiso wemvula wawungenziwanga ngenjongo yokudala iirekhodi kunye nedatha yokucaciswa kwemozulu yendawo. Incede kuphela ekuphuculeni isivuno sezityalo.
Minyaka le imvula yayilinganiswa ukwazi ukuba yeyiphi amanzi afumanekayo kwizityalo. Isidingo sokulinganisa imvula sivela kwiimfuno zezolimo. Oku kungqinwa yimibhalo yenkolo eyafunyanwa ePalestine eyayithetha ngendlela ukuna kwemvula okukuchaphazele ngayo ukubonelelwa ngamanzi afanelekileyo okunkcenkceshela izityalo. Ke ngoko, ngelo xesha ukubonelela kunye nezolimo kuphela kwezinto ezazibalulekile. Babengayifuni loo datha yokuqikelela imozulu okanye uqikelelo lwemozulu.
Kamva kamva ngo-1441 eKorea, igeji yokuqala yemvula yenziwe ngobhedu kwaye ngokuvulwa okuqhelekileyo kwaphuhliswa. Le gauge yemvula isebenze phantse iminyaka engama-200, xa ngo-1639, uBenedetto Castelli, umfundi ka UGalileo Galilei, ikwazile ukwenza imilinganiselo yokuqala yemvula eYurophu. Esi sixhobo sasiphethwe ngesandla kwaye siphawulwa kwinqanaba lemvula ebelikhona kangangeeyure.
Ngomnyaka we-1662 kwaqala ukulinganisa imvula kunye neebhakethi ezitsalayo. Esi sixhobo sasetyenziselwa ukurekhoda kungekuphela nje idatha yemvula kodwa kunye nedatha yemozulu enje ngobushushu bomoya kunye nolwalathiso lomoya.
I sebenza njani
Isixhobo kufuneka sibekwe kwindawo ephezulu ukuze sikwazi ukurekhoda amanqanaba emvula. Ngale ndlela, ayizukuchaphazeleka kulo naluphi na uhlobo lomqobo. Ngexesha lokulinganisa, isikhongozeli siqala ukugcina amanzi emvula kancinci kancinci kwaye, akugqiba, Kuxhomekeke kwimilinganiselo oyiphawulayo, iya kuba yimvula kuloo ndawo.
Iyakwazi ukulinganisa imvula, isichotho, ikhephu, ukuqengqeleka, kunye nokuqhwithela, nangona ingalinganiseli inkungu okanye umbethe. Oku kungenxa yento yokuba ngumbandela wokunciphisa amaconsi amanzi kwaye awunakulinganiswa ngamanqaku kwiglasi. Ubume bojikeleze umzimba kwaye inenxalenye emile okwefaneli yokuqokelela amanzi amaninzi.
Iindidi zegeyiji yemvula
ngezandla
Luhlobo oluqhelekileyo. Sisalathiso esilula nesichanekileyo sobungakanani bemvula ewela kwindawo. Yenziwe ngesikhongozeli sesilinda esinezinga lokuthweswa isidanga. Ukuphakama kwamanzi efikelela kuwo kulingana namaqondo emvula. Ilinganiswa ngeemilimitha.
Iitotali
Olu hlobo lwegeyiji yemvula yenye yezona zichanekileyo. Banoxanduva lokuqokelela amanzi awela ngefanele. Le faneli iphinda ijikeleze amanzi kwisitya esiphumeleleyo. Zihlala zibekwe kubude obuthile emhlabeni kwaye ukuwa kwamanzi kubhalwa rhoqo kwiiyure ezili-12. Esona siphene kwezi gaji zemvula kukuba ixesha apho imvula yenzeke alinakuchazwa.
USiphon
Ngolu hlobo lwegeyiji yemvula Ixesha lemvula lingaziwa ngokuchanekileyo. Inombhobho ojikelezayo ojikeleza ngesantya esingaguquguqukiyo. Iphumelele ngosiba ngaphakathi oludada ngokuthe nkqo. Ukuba akunjalo, usiba luphawula umgca othe tyaba.
Ukuphinda kabini ibhakethi
Esi sixhobo siqokelela amanzi ngefaneli kwaye sikhokelele kwibhakethi elincinci elingunxantathu elinokwenziwa ngesinyithi kunye neplastiki. Inentsiba kwindawo eseleyo yokulinganisela. Nje ukuba ifike kwimvula elindelekileyo, edla ngokuba yi-0,2 mm, Utshintsho lokulingana lwenzeka kwelinye ibhakethi, ngelixa ibhakethi lokuqala libala kwakhona.
Ukubaluleka kwegeyiji yemvula bekukhona ukusukela eGrisi yamandulo. Nangona ekuqaleni yayiluncedo ekuphuculeni amasimi ezolimo, kwakubalulekile ukuqinisekisa ngokutya kwabemi. Kule minyaka idlulileyo, ukubaluleka kwayo kukhule ngendlela yokuba kungasebenzi kuphela kwizityalo, kodwa nokulinganisa imvula ukuze kufundwe ngemozulu kwihlabathi liphela kwaye kufunyaniswe utshintsho lwemozulu.
Ndiyathemba ukuba ngolu lwazi ungafunda banzi malunga negeyiji yemvula.
