Kana ari mugomo achinaya mvura polar usiku? Mhinduro yacho iri pachena

On hwokumusoro nekwakapinza Europe, Asia uye America anotonga achinaya mvura. Kumaodzanyemba hemisphere zvakanyorwa chete kuwanikwa zvimwe zvitsuwa Antarctic. achinaya mvura mapazi Anotambanudza achitevedza kuchamhembe kumiganhu Russia, kushambidzwa kuburikidza nechando Arctic Ocean.

Unique uye zvakakomba dzinongoitika mapazi

In nechitarisiko riri rima, yaisazoraramika uye gwenga munzvimbo. Mwedzi mipfumbamwe yegore pano rikunde yechando, refu uye hakunakidzi anotambanudza polar usiku. Risati treeless, akaberekera pasi anouya chiedza chando norutara mwedzi. Zvishoma shimmer nyeredzi chete. Happy tarisa zvisingawanzoitiki, nakisisa runako ari Aurora borealis.

On ivhu ichi asingabereki, chando-vakasungwa nefararira, uye dzimwe nguva vamazana metres yakadzika, kukura isingawanzowanikwi mosses uye lichens kusurukirwa. Just kumaodzanyemba akagadzirisa pasi uye zvishoma kukura nemiti midzi peaty ivhu.

Kuti tipindure mubvunzo kana pane mugomo achinaya mvura iri polar usiku, zvinokosha kunzwisisa tsanangudzo mararamiro ichi.

zvinoshamisa biome

Mountain achinaya mvura, zvakare kunzi "refu", anonzi magetsi maonero mararamiro ari wehunyambiri muenzaniso zvikamu. Nharaunda iyi rwokuzvarwa biome pakugadzwa chando uye chando kugomo-bhandi. muganhu wayo rinoenderana kumuganhu mutsetse masango uye inopfuura nomunyika snowline. Muganhu Climate mapazi - avhareji muzhizha isotherm + 10 °. mapazi ichi kunoratidzwa dzemakomo gomo neeSultan kuti Sub-chando uye vakadzikama zvikamu.

Huru kusiyana kubva YOMUMAKOMO achinaya mvura kweArctic - yakanakisisa ivhu abudise uye murombo ivhu mvura-Logged.

The mamiriro okunze ari kuchamhembe munyika

Scientific Tsanangudzo kana pane mugomo achinaya mvura, polar usiku, ndiyo okunze yacho. Nokuti nzvimbo idzi dzinoratidzwa chaizvo tembiricha yakaderera iri akatura maererano adiabatic gradient 1 ° C mumwe 100-200 mamita kukwirira. Nokuti randinenge mugodhi achinaya mvura kunaka avhareji mhepo tembiricha. Pano zviri hunodzorwa mhepo ine simba, uye zuva nemwaranzi runozivisa kumusoro basa. The mapazi mamirire rarefied mhepo maldistribution ndichibvunza kuchinja kwayo mwando. Snow pabutiro ari kuparadzirwa non-noruvara.

Kujekesa kana pane mugomo achinaya mvura iri polar usiku, uye achabatsira kwaanogara nzvimbo. Izvi dzinongoitika Fani kunoitika pamusoro munzvimbo gomo, idzo inoona nezvenjodzi mukati kweArctic Circle. The polar usiku hazviitiki kana dzakakwirira iri zvikuru nechokumaodzanyemba munzvimbo dzinongoitika, izvo tinoberekwa kutonhora. Pashure pezvose, munharaunda ino alternation neusiku kwakafanana muzvinhu masango coniferous uye Deciduous. Chinhu chikuru zvimiso panowanikwa polar usiku ari chaizvo kuramba kuvapo yakaderera tembiricha. Uye chete chikonzero chinoita ichi ndicho nenzvimbo Latitude, kunyange rwokumusoro, kunyange kumaodzanyemba. Chinhu chikuru - kufadza chinhambwe kubva kuchamhembe kana kumaodzanyemba kweArctic Circle kuti mapango.

Winter: kuchitonhora uye kwegore risingapindiki rima

Sort kana pane mugomo achinaya mvura, polar usiku, edza kuumba tsanangudzo ayo uye urefu. Izvi dzinongoitika Fani inonzi nguva kana zuva asimo pamusoro pajengachenga kupfuura zuva. Ichi migumisiro zvinodiwa kwekona pakati 23.5 ° akabatana kuti vachishandisa kutenderera nyika kusvikira ecliptic ndege. Pfupi yenguva (mazuva maviri), polar usiku rinovapo panguva Latitude kweArctic Circle. The kunonyanyisa nguva yose Chiitiko - inenge mitanhatu, izvo zvakafanana nezvaiitwa vamwe South Pole.

Polar usiku muna achinaya mvura chinogara avhareji 1-2 mwedzi uye anotora nzvimbo muchando. mwaka Izvi zvakaoma chaizvo ekunze. Saka, paavhareji tembiricha iri January wakachengetwa kumativi -25-35 ° C. makomo Snow-dzavhara, azara mhepo nechando, muchando kutarisa upenyu. Kunyange zvachose ugere mugomo achinaya mvura - poro - uchitsvaka zvokudya kazhinji otkochevyvaet zasi. Heavy ezvinhu utsinye nharaunda iyi, uye polar usiku - zvakaoma kuti hunhu zvose zvipenyu zvose.
