Uyini nokwehla. Ukukhuphuka nokwehla ku Murmansk futhi Arkhangelsk

izivakashi eziningi iholidi baye at zokungcebeleka Thailand noma eVietnam, sibhekene ezinjalo zemvelo njengoba namagagasi olwandle. Ngo amanzi ethile ngehora ngokuzumayo zivame ukufiphala kusukwa evamile, eneka phansi. Kuyamjabulisa abendawo: abesifazana labantwana iya ebhange ukuqoqa kwadingeka isikhathi kuphunywe, kanye ekubunjweni wave ezinamagobolondo nezinkalankala. Futhi ngesinye isikhathi kolwandle iqala ukuhlasela, kwathi cishe ngemva eziyisithupha amahora emi Chaise longue ibanga wokusemanzini. Kungani lokhu kwakwenzeka? Siyini isizathu salokhu? Kungani, isibonelo, i-Black noma Azov kwezilwandle thina awuligubhi lelo amagagasi, futhi eduze Murmansk ezingeni amanzi nsuku zonke iyehla iyenyuka zibaluleke? Ake sibheke lezi izimfihlakalo olwandle.

Yemvelo ka zemvelo

Kuyindida njengoba imbangela namagagasi Emhlabeni engumyeni wakhe. Kunengqondo ukuphetha ngokuthi ngokuvamile ekujuleni ongagcwali wezilwandle komhlaba nendikimba esemkhathini? Iqiniso lokuthi hhayi Umhlaba kuphela ophethe Moon emzileni Luhambo yayo. Le nqubo kuyinto evamile. Inyanga Ubuye isisindo (nezincane), ngakho-ke amandla adonsela phansi wenza eplanethini yethu. Inyanga Stones engabuzi, kodwa akulula ezinjalo, njengoba amanzi ikani. Umhlaba Ocean sengathi inyanga uzimisele phambili. Futhi njengoba Umhlaba uhamba satellite kanye orbit (kithi - esibhakabhakeni), khona-ke amanzi okusezingeni eliphezulu ihamba ngemuva kuye. Imperceptible olwandle oluvulekile, igagasi kuzibonakalisa ngasogwini, e amatheku emincane futhi emanzini angajulile, okubangela ukukhuphuka nokwehla. Ilanga sithinta amandla okudonsa ukugudluka olukhulu lwamanzi. Lokhu mass yokukhanya mkhulu kakhulu kunaleyo Inyanga, kodwa izikhathi ezingamakhulu amane ezikude Umhlaba kuka inyanga yethu. Futhi ngenxa yokuthi inyanga solar amagagasi kabili buthaka.

I PERIODICITY kwamagagasi

Uma ucabangisisa, eliphakeme amanzi kufanele libukwe okwamanje lapho inyanga yisithiyo zenith. Lapho nyanga ngesikhathi nadir, silindele ongaphakeme, kusale wave. Kodwa into eyinqaba: ukukhuphuka nokwehla kuyagcinwa kabili ngosuku. Futhi kwaba okwesibili ngesikhathi inyanga ngaleso nadir (iphuzu okuphambene-zenith). Lokhu kungenxa yokuthi i-satellite namanje edonsela amanzi, ngisho lonke ukushuba wonke. Ngakho, izinga kwezilwandle kungafaniswa i lesiyingi, emaphethelweni side zazo amanga ku-eksisi okufanayo the Moon, futhi isicaba perpendicular ke. Ngaphandle-ke akudingekile ukuba uchithe esibaluleke kangaka njengoba efanele ukujikeleza Umhlaba emhlabeni axis awo. uquqaba ezinkulu amanzi ngaphansi kwethonya amandla centripetal wave ifomu amaphuzu amabili Okusizayo okuphambene emhlabeni.

Kungani amandla lesi simanga akuyona iyunifomu ezingxenyeni ezahlukene Zomhlaba

Okwazekayo, ezweni lonke, kumelwe sigcine efanayo amandla namagagasi. Nokho, Murmansk, kungaba ozibongayo ukuthi embankments yayo lamanzi linyuka by amamitha amane, kuyilapho Gulf ngasogwini Petersburg kuyinto engokwemvelo kancane obonakalayo, futhi ngisho nangalesosikhathi kuphela emanzini angajulile. Isici esiyinhloko ezikhulisa ukubonakaliswa igagasi, ubuhlobo ngamanzi olwandle. Ezilwandle maphakathi nezwe - Sea, oLwandle iBaltic, Marmara, LwaseMedithera ikakhulukazi Azov - into cishe non-akukho. Izinga amanzi ongasukuma ngu 5-10 amasentimitha, engasekho.

Esinye isici ukuthi kungaba ngcono ukugeleza futhi kungasaziwa is Kuhlehliswe ogwini. Amatheku ewumngcingo nge phansi engajulile, lezi zenzakalo kuvetwa eziningi, unamandla. Uma esizalweni somfula has isiqondiso empumalanga (okuphambene ukudlula inyanga), khona-ke wave olwandle ushayela amanzi umfula, ngezinye izikhathi ezimbalwa amashumi amakhilomitha ukusuka olwandle. Lokhu kuvezwa obala kunazo ngokucacile E-Amazon. Amanzi evuka ukuba amamitha amane. Inland wave ehamba ngesivinini 25 km / h.

Yini kuthinta ukushuba lomkhuba

Ukuhlala isikhathi eside ogwini efanayo, siphawula ukuthi ngezinsuku ezahlukene igagasi kuyalithinta ukungalingani. Ngesinye isikhathi kolwandle kuziwa ebhishi kuba okukhulu kakhulu, futhi kude naye. Ngemva kwesonto, ukukhuphuka nokwehla musa ihluke kanzima kanjalo. Isizathu itholakala isenzo elangeni. Sesiphawulile ukuthi ukukhanya futhi uheha kukholamu amanzi, nakuba ayengazi kakhulu ngendlela the Moon. Ngakho-ke, ku geography ezimbili zama-amagagasi - syzygy futhi quadrature. Konke kuncike izikhundla isihlobo of the Moon futhi Sun isihlobo ukuba Earth. Uma ukukhanya kanye satellite kuyiplanethi yethu zitholakala eyodwa-eksisi (okuthiwa syzygy), ukushisa komzimba sibe sibi kakhulu. Lapho ilanga nenyanga ahlelwe at engele kwesokudla (quadrature), nethonya lazo amanzi Luhambo incipha. Khona-ke kukhona isimo aphansi.

irekhodi-full

Likuphi endaweni namagagasi eliphakeme? Indawo yokuqala lapho kwabelwana khona ngamaphuzu amabili womhlaba. Zombili zingezakhe eCanada. It Ungava Bay enyakatho Quebec kanye eChwebeni Fundy, phakathi Nova Scotia futhi New Brunswick. entwasahlobo Kukhona tide ifinyelela nesishiyagalombili amamitha! Kodwa lapho ilanga nenyanga kukhona endaweni, izinga lamanzi ukhulisa ithuna - amamitha ayishumi nanhlanu nengxenye. EYurophu lehla ngokushesha inani igagasi enkulu ebonwe edolobheni Saint-Malo, esifundazweni isiFulentshi Brittany. Ngenxa ubunjalo ugu futhi ukugeleza Channel Isenzakalo esingokwemvelo is iyakhula futhi ukuphakama kwamanzi ifinyelela 13.5 m.

indawo yesithathu kwi ukuphakama amagagasi (cishe eyishumi nantathu amamitha) ithatha Penzhina Bay oLwandle Okhotsk. Le ndawo futhi umnikazi irekhodi e lonke Pacific ogwini. Zemifula kanye waleso futhi alethe izinguquko namagagasi. Arkhangelsk, sise confluence Northern Dvina olwandle, uyazi into ezifana Manichaean. Lokhu akusiyo into efana isimo. Yena esukela umfula amanzi emfuleni.

Tides e Murmansk

Mezen Bay iWhite Sea futhi inama amanzi ukufika Hardball - a egcwele amamitha ayishumi! Nokho, ethekwini Murmansk umehluko phakathi emanzini okugcwele ongaphakeme (ukuphakama ekupheleni igagasi) is hhayi okungaka - ingqikithi amamitha amane. Kodwa njengoba ogwini lapha engajulile, emnyango ngobumnene ezitshekile kuze kufike elwandle, ke kuveza endaweni enkulu. Izivakashi iya ngqo ukubukela isimo. Lapho amahora ambalwa edlule zineminyaka amagagasi, izinyoni zululeka, ubuka imigodi ka mollusk kanye ezinamagobolondo. Futhi ukuthi umkhumbi akaziqhathululanga esihlabathini lapho ushiya bay, igunya port has a ithebula ekhethekile, okuyinto yakhelwe, lapho ngosuku olunikeziwe iqala tide, igagasi ongaphakeme.

Kola Bay

Lena indawo emangalisayo kule Murmansk esifundeni. It egeza Nordkapp zamanje, okuyinto nehlumela Gulf Stream. Siyabonga uquqaba olukhulu lwamanzi efudumele kolwandle akuyona simisiwe, kodwa frost ogwini kungaba afinyelele ezingeni lokushisa -24 nasesikhathini enkabeni yaleli zwekazi, futhi zonke degrees -34. Eqinisweni Kola Bay - a Fjord, kokushayeka ezweni amakhilomitha angu-60. It ebbs bese ugelezela agqamise amandla umoya, okuyinto ashaye maqondana ezingwini ulwandle. Izinga olwandle amanzi okusezingeni eliphezulu antante amamitha amane.
