I-Barograph

linganisa umfutho womoya

Ingcindezi yasemkhathini yinto ebaluleke kakhulu okumele siyibhekele kwezulu uma sifuna ukwenza izibikezelo ezinhle futhi sifunde ngokuziphatha kwesimo sezulu. Zonke izimo zasemkhathini nezesimo sezulu zibekelwa izinguquko ekucindezelekeni komkhathi. Njengoba akuyona into ephathekayo, kunzima ukufunda ukukala ingcindezi yasemkhathini. Kunezinsimbi eziningana zesimo sezulu ezingalinganisa lawa mavelu. Enye yazo yi- i-barograph.

Kulesi sihloko sizokutshela ngazo zonke izici, ukusebenza nokubaluleka kwe-barograph.

Ukubaluleka kokulinganisa ingcindezi yasemkhathini

i-barograph yasendulo

Yize kubonakala kungenjalo, umoya uyasinda. Asisazi isisindo somoya kwazise sicwile kuwo. Umoya unikeza ukumelana lapho sihamba, sigijima noma sigibela imoto, ngoba, njengamanzi, iyindlela esihamba ngayo. Ubuningi bamanzi buphakeme kakhulu kunobo bomoyaYingakho emanzini kunzima ukuthi sinyakaze.

I-barograph iyithuluzi elisiza ukunikela ukufundwa okuqhubekayo kwesilinganiso samanani wengcindezi yasemkhathini. I-barograph iyidivayisi lapho amanani angatholakala nge-barometer angarekhodwa khona. Le divayisi ifakwe ku-barograph futhi ukufundwa kwamanani akutholakali nge-mercury. Kususelwa ekufundeni okutholwe ngokuchotshozwa okukhiqiza ingcindezi yasemkhathini ezingxenyeni ezincane zensimbi ezinjenge-cylindrical shape.

Ukuvikela ingcindezi ekulimaleni ukwakheka kwe-barometer, iziphethu zosayizi omncane ziyafakwa ezivimbela amaphilisi wokulinganisa ekuchotshozweni. Ipeni lingabekwa ngaphezulu kwalo, elibhekele ukuqondisa isigubhu esijikelezayo. Lesi sigubhu siphethe ukujikeleza ukuze iphepha elithweswe iziqu likwazi ukuhanjiswa futhi imayela lilandele amanani engcindezi asemkhathini ephepheni. Ngenxa yokusetshenziswa kwe-barograph, kungenzeka ukwazi nokubona ngokuningiliziwe izinguquko ezahlukahlukene eziqhubekayo lapho i-barometer yenziwa khona. Ngaphezu kwalokho, singakwazi ukwazi amanani wengcindezi asemkhathini.

Amarekhodi ku-barograph

linganisa ingcindezi yasemkhathini

Lapho umoya uzolile, kwaziwa nge-meteorology njengexhaphozi le-barometric. Lapha kubhekiselwa lapho amagrafu angaqopha amanani wezinguquko ezinhle noma ezingezinhle. Yilapho izinguquko zesimo sezulu zibhekiswa khona lapho olunye lwalezi zinguquko luvela ngokungazelelwe. Ungahumusha kalula lezi ziqongo ezaziwa nangokuthi amazinyo abonwa.

Ukusebenza kwalezi zinsizakusebenza kuncike ekushikashikeni okuhlukahlukene kwesivalo esinomshini ngaphakathi ozwelayo ekuguqulweni kwengcindezi yasemkhathini. Ngale ndlela, ingacindezelwa uma kunezingcindezi eziphezulu futhi yeluleke uma kunezingcindezi eziphansi. Ukuhamba kwayo kudluliswa ngohlelo lwamalevers axhunywe engalweni ebhekele ukuqopha imininingwane ngosiba. Ipeni imvamisa lolohlobo lwesipuni futhi lisekugcineni. Ukubhaliswa kwenziwa ku-roller ezungeza kwi-eksisi yayo ngenxa yendlela yewashi yangaphakathi.

Kunamanye amamodeli okuthi, ngokuya ngosayizi we-roller, angahlala ngaphezulu noma ngaphansi. Izinhlobo eziningi zivame ukuhlala cishe isonto elilodwa kuthatha isikhathi eside ukuthi ipeni lisebenzise uyinki walo bese libhala kulo lonke iroli.

Kunengqondo ukucabanga ukuthi uma ingcindezi yasemkhathini ingenxa yesisindo somoya ngaphezu kwephuzu elithile ebusweni bomhlaba, kufanele sicabange ukuthi iphuzu liphakeme, ingcindezi izoba phansi, ngoba inani lomoya iyunithi ngayinye nalo lincane. ngenhla. Ingcindezi yasemkhathini ilinganiswa njengejubane, isisindo, njll. Kukalwa kuma-atmospheres, millibars, noma mm Hg (millimeters of mercury). Imvamisa ingcindezi yasemkhathini ekhona olwandle ithathwa njengereferensi. Lapho kuthatha inani lomkhathi o-1, ama-millibars ayi-1013 noma u-760 mm Hg futhi ilitha lomoya linesisindo esingu-1,293. Iyunithi esetshenziswa kakhulu yizazi zezulu yilelo lama-millibars. Onke lawa mavelu abhaliswe ku-barograph.

I-Barograph ne-barometer

i-barograph

Empeleni, ukuze kukalwe ingcindezi yasemkhathini, kusetshenziswa ama-barometers. Kukhona ama-barometers ezinhlobo ezahlukahlukene. Okwaziwa kakhulu yi- i-barometer ye-mercury eyasungulwa nguTorricelli. Yiphubhu emise okwangu-U enamagatsha avaliwe lapho kudonswe khona i-vacuum, ukuze ingcindezi engxenyeni ephezulu kakhulu yaleli gatsha ibe zero. Ngale ndlela, amandla akhishwa emoyeni kukholamu eliketshezi angalinganiswa nengcindezi yasemkhathini ikalwe.

Ingcindezi yasemkhathini ingenxa yesisindo somoya phezu kwephuzu elithile ebusweni bomhlaba, ngakho-ke, lapho leli phuzu liphakama, ingcindezi izoba phansi, ngoba inani lomoya elincane likhona. Singasho ukuthi umfutho womoya uncipha phezulu. Isibonelo, entabeni, inani lomoya engxenyeni ephakeme kakhulu lingaphansi kwalelo lolwandle, ngenxa yokwehluka kobude.

Ingcindezi incipha ngobude ngokujwayelekile. Lapho sikhuphuka phezulu, ingcindezi incipha futhi sinamandla amancane emoyeni. Into ejwayelekile ukuthi yehla ngesilinganiso esingu-1 mmHg njalo ngamamitha ayi-10 ukuphakama.

Ubudlelwano nezimo zezulu

Njengoba sishilo ngaphambili, ingcindezi yasemkhathini ingenye yezinto eziguquguqukayo ezibalulekile ekubikezelweni kwezimo zezulu. Izimvula, imimoya, iziphepho, njll. Zihlobene namazinga wengcindezi yasemkhathini. Ngesikhathi esifanayo, Lawa magugu ahlobene ngqo nokuphakama esikukho nenani lesigameko semisebe yelanga. Yimisebe yelanga ekhiqiza ukunyakaza kwenqwaba yomoya edala izinto ezahlukahlukene zomkhathi esizaziyo.

Ngakho-ke, ukubaluleka kokulinganisa ingcindezi yasemkhathini kanye nokusetshenziswa kwe-barograph ne-barometer kubalulekile ekubikezelweni kwesimo sezulu.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nezici nokusetshenziswa okunikezwa i-barograph.
