Iyini ingcindezi yasemkhathini futhi isebenza kanjani?

Ingcindezi yasemkhathini

Esimweni sezulu, ingcindezi yasemkhathini Kuyinto ebaluleke kakhulu okufanele uyicabangele lapho ubikezela futhi ufunda ngokuziphatha kwesimo sezulu. Amafu, izivunguvungu, izivunguvungu, imimoya, njll. Ngokuyinhloko kulungiswa izinguquko ekucindezelekeni komkhathi.

Kodwa-ke, ingcindezi yasemkhathini akuyona into ephathekayo, into engabonakala ngeso lenyama, ngakho-ke kunabantu abaningi abawuqondayo umqondo, kepha abazi ngempela ukuthi uyini.

Yini ingcindezi yasemkhathini?

Noma ngabe kubonakala ngathi cha 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 bomoya, yingakho kunzima kakhulu kithi ukuhamba emanzini.

Ngandlela thile, umoya unamandla kithi nakukho konke. Ngakho-ke, Singachaza ingcindezi yasemkhathini njengamandla akhiqizwa umoya osemkhathini ebusweni bomhlaba. Ukuphakama kobuso bomhlaba ngokuqhathaniswa nolwandle, kwehlisa umfutho womoya.

Ingcindezi yasemkhathini ilinganiswa kumaphi amayunithi?

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 ngo- ama-atmospheres, ama-millibars, noma i-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 kanti ilitha lomoya linesisindo esingu-1,293 amagremu. Iyunithi esetshenziswa kakhulu yizazi zezulu yilelo lama-millibars.

Ukulingana kwezilinganiso zengcindezi yasemkhathini

Kalwa kanjani ingcindezi yasemkhathini?

Ukuze ulinganise ukucindezela koketshezi, izikali zokucindezela. Isetshenziswa kakhulu futhi kulula ukuyisebenzisa i-tube manometer evulekile. Ngokuyinhloko ithubhu elimise okwe-U eliqukethe uketshezi. Umkhawulo owodwa webhubhu usecindezelweni lokukalwa kanti elinye lixhumana nomoya.

para Linganisa umoya noma ingcindezi yasemkhathini usebenzisa 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.

Le yindlela kulinganiswa ngayo ingcindezi yasemkhathini

Njengoba sishilo ngaphambili, ingcindezi yasemkhathini ingenxa yesisindo somoya phezu kwephuzu elithile lobuso bomhlaba, ngakho-ke, leli phuzu liphakeme, ingcindezi iphansi, ngoba kuncane inani lomoya okhona. Singasho ukuthi umfutho womoya uncipha phezulu. Isibonelo, entabeni intengo yomoya engxenyeni ephezulu incane kunaleyo ebhishi, ngenxa yokwehluka kobude.

Esinye isibonelo esithe xaxa yilokhu okulandelayo:

Izinga lolwandle lithathwa njengereferensi, lapho ingcindezi yasemkhathini inamanani ayi-760 mm Hg. Ukubheka ukuthi ingcindezi yasemkhathini iyancipha yini ukuphakama, siya entabeni enesiqongo esiphakeme cishe ngamamitha ayi-1.500 635 ngaphezu kogu lolwandle. Senza isilinganiso futhi kuvela ukuthi kulokho kuphakama, ingcindezi yasemkhathini ingu-XNUMX mm Hg. Ngalesi sivivinyo esincane, sibheka ukuthi inani lomoya esiqongweni sentaba lingaphansi kwalelo lolwandle futhi, ngakho-ke, amandla akhishwa umoya ebusweni kanye nathi mancane.

Ukuhluka kwengcindezi yasemkhathini ukuphakama

Ingcindezi yasemkhathini nokuphakama

Iphuzu elibalulekile okufanele ligcinwe engqondweni ukuthi ingcindezi yasemkhathini ayinciphisi ngokulingana ngobude ngoba umoya uwuketshezi olungacindezelwa kakhulu. Lokhu kuchaza ukuthi umoya osondelene nengaphezulu yomhlaba ucindezelwe isisindo somoya uqobo. Okungukuthi, izingqimba zokuqala zomoya eziseduze nomhlabathi iqukethe umoya omningi ucindezelwe umoya ophezulu (umoya ebusweni mkhulu, ngoba kunomoya omningi ngeyunithi yevolumu ngayinye), ngakho-ke ingcindezi iphezulu ebusweni futhi ayinciphi ngokulingana kusukela inani le Umoya awunciphi ngokuqinile ekuphakameni.

Ngale ndlela singasho ukuthi ukusondelana nolwandle, okwenza ukukhuphuka okuncane ukuphakama kubangele ukwehla okukhulu kwengcindezi, ngenkathi sikhuphuka, sidinga ukuya phezulu kakhulu ukuzwa ukwehla kwengcindezi yasemkhathini ngezinga elifanayo.

Iyini ingcindezi olwandle?

Ingcindezi yasemkhathini olwandle 760 mm Hg, elingana namamiligibhu ayi-1013. Ukuphakama kokuphakama, ingcindezi yehla; empeleni yehliswa ngo-1mb kuyo yonke imitha esikhuphuka ngayo.

Ingcindezi yasemkhathini iwuthinta kanjani umzimba wethu?

Imvamisa kuba nezinguquko ekucindezelekeni komkhathi lapho kunezivunguvungu, ukungazinzi komkhathi noma imimoya enamandla. Ukukhuphuka ukuphakama kuthinta nomzimba. Izintaba ngabantu abahlupheka kakhulu kulezi zinhlobo zezimpawu ngenxa yezinguquko kwingcindezi njengoba bekhuphuka izintaba.

Izimpawu ezivame kakhulu yilezi ikhanda, izimpawu zesisu, ubuthakathaka noma ukukhathala, ukungahlali noma isiyezi, ukuphazamiseka kokulala, phakathi kwabanye. Isilinganiso esisebenza kahle kunazo zonke ngokumelene nokuvela kwezimpawu zokugula ezintabeni ukwehla kuya ezindaweni eziphansi, noma ngabe kungamamitha nje ambalwa.

Izimpawu zengcindezi yasemkhathini

Abagibeli bezintaba abaningi baphathwa yikhanda lapho bekhuphuka kakhulu.

Ingcindezi kanye nokungazinzi komkhathi noma ukuzinza

Umoya unamandla ashukumisayo alula futhi uhlobene nobuningi bawo nokushisa kwawo. Umoya ofudumele awuminyene kakhulu futhi umoya obandayo uyajiya. Yingakho uma umoya ubanda kakhulu uvama ukwehla phezulu futhi okuphambene lapho kufudumele. Le mpilo yomoya idala ushintsho kwingcindezi yasemkhathini ebangela ukungazinzi noma ukuzinza emvelweni.

Ukuzinza noma i-Anticyclone

Lapho umoya ubanda futhi wehla, umfutho womoya uyanda ngoba kunomoya omningi ngaphezulu ngakho-ke, unamandla amakhulu. Lokhu kubangela ukuzinza komkhathi noma okubizwa nangokuthi i-anticyclone. Isimo se anticyclone Kubonakala ngokuba yindawo enokuthula, ngaphandle kwemimoya ngoba umoya obanda kakhulu futhi osinda kakhulu wehla kancane ujikeleze ngendlela eyisiyingi. Umoya ujika cishe ngokungacaci iwashi enyakatho Nenkabazwe nangakwesobunxele ohlangothini lwaseningizimu.

Okunye okumele ukukhumbule ukuthi umoya obandayo nomoya oshisayo awuxubeki ngokushesha ngenxa yobuningi bawo. Lapho lezi zingaphezulu, umoya obandayo uphushela umoya oshisayo phezulu obangela ukwehla kwezingcindezi nokungazinzi. Kwabe sekwakhiwa isiphepho lapho kubizwa khona indawo yokuxhumana phakathi komoya oshisayo nobandayo ngaphambili.

Amamephu wesimo sezulu nesimo sezulu

I-Los amamephu wesimo sezulu zenziwa yizazi zezulu. Ukwenza lokhu, basebenzisa imininingwane abayiqoqayo eziteshini zezulu, ezindizeni, kumabhaluni azwakalayo nakuma-satellite okwenziwa ngawo. Amamephu akhiqizwayo amele izimo zomkhathi emazweni ahlukahlukene nezindawo ezifundwe. Amanani ezinye zezimo zezulu ezifana nengcindezi, umoya, imvula, njll.

Amamephu wesimo sezulu asithakazelisayo ngalesi sikhathi yilawo asikhombisa ingcindezi yasemkhathini. Kumephu yengcindezi imigqa yengcindezi elinganayo yomkhathi ibizwa ngokuthi ama-isobars. Okusho ukuthi, njengoba ingcindezi yasemkhathini iguquka, imigqa eminingi ye-isobar izovela ebalazweni. Izinqe ziyabonakala nasemabalazweni okucindezela. Ngenxa yalezi zinhlobo zamamephu kungenzeka ukunquma ukuthi isimo sezulu sinjani nokuthi sizoguquka kanjani emahoreni ambalwa alandelayo ngezinga eliphakeme kakhulu lokuthembeka, kuze kufike kumkhawulo wezinsuku ezintathu.
