Atmospheric fronts - chii ichi? Ndezvipi?

Watch kuchinja ari ekunze zvinonakidza chaizvo. Zuva anopa nzira kunaya, mvura - chando, uye kupfuura zvose ichi siyana rokuridza gusty mhepo. Somwana, rinoita kuyemurwa uye kushamisika vanhu vakwegura - chido kunzwisisa mashandiro acho. Ngatiedzei kunzwisisa chii anoumba ekunze uye sei kurondedzera ratinoona fronts.

Muganhu mhepo makore

Zvatinosiita maonero "pamberi" - rechiuto izwi. Ndicho mutsetse uri pane kudhumhana mauto muvengi. Uye pfungwa ratinoona fronts - muganhu yakajairika maviri mhepo makore kuti vanoumba pamusoro guru penyika nzvimbo Earth.

By kuda zvakasikwa, murume aikwanisa kurarama, ichishanduka uye nyuchi zvose nharaunda huru. Troposphere - rezasi chikamu paNyika mumhepo - anotipa okisijeni uye ari kugara zvitange. All inoitwa yoga mhepo makore vakabatana kwakakurumbira kuwanika uye parameters zvakafanana. Pakati dzinokosha parameters ichiita sokuti izvi akatsunga vhoriyamu, tembiricha, kumanikidza uye mwando. Panguva sangano zviyereso siyana anogona wekuita uye dhumhana. Zvisinei, havana havazombokundikani pamiganhu yavo uye hazvipindiri pamwe mumwe. Atmospheric fronts - vari munzvimbo soprikosayutsya mhepo makore uye ekunze RINOFAMBIRA kuitika.

A Nhoroondo shoma

Pfungwa yokuti 'ekunze mberi "uye" chiso pamberi "haana simuka voga. Vakanga kwakamboitwa meteorology Norwegian musayendisiti J. Bjerknes. Izvi zvakaitika muna 1918. Bjerknes akaratidza kuti mhepo yakapoteredza fronts - Ndiwo dzinokosha vamapoka ichitanga mumhepo mukuru uye pakati akaturikidzana. Zvisinei, kusvikira Norwegian Research, shure muna 1863, ari Admiral Fitzroy yakati kuti chisimba ratinoona pezvakaitwa kutanga yokuitira mhepo makore vanobva dzakasiyana dzenyika. Asi panguva masayendisiti haana kuteerera izvi zvinoonekwa.

Bergen School, waiva mumiririri Bjerknes, vakabata zvake zvaanorumbidza, asi vakauyawo ose ruzivo uye zvekungofungira akaita ndamboudzwa vanoona uye nenyanzvi pamwe, uye kupa navo coherent musayenzi hurongwa kwete chete.

By tsanangudzo, imwe pemvura vachida, inova ine yokuchinjira pakati akasiyana mhepo dzemvura, inonzi chiso mberi. Asi mhepo yakapoteredza fronts - the Mapping nechemberi hukawanika panguva ekunze mepu. Kazhinji mumhepo pamberi Kuchinja nharaunda iri makamuisa panguva nomumativi vanosimuka dzakakwirira panguva iyo Blurred kusiyana pakati mhepo makore. Kazhinji, izvi pachikumbaridzo kukwirira kubva 9 kusvika 12 km.

kwoushamwari mberi

Atmospheric fronts zvakasiyana. Ivo vanovimba kutungamirirwa kufamba noushamwari uye kutonhora arrays. Kune mhando nhatu fronts: chando, ichidziya uye occlusion rakaumbwa panzvimbo nokuvhara fronts siyana. Ngatikurukurei kuti tiri kwoushamwari uye kuchitonhora ratinoona fronts.

Warm mberi - kufamba mhepo makore dzakadaro, apo mhepo inotonhora anopa nzvimbo anodziya. Kureva kuti, wakakwidzwa tembiricha mhepo, kutama, riri munzvimbo dzaitongwa chando mhepo guru. Uyezve, unomutswa kumusoro pamwe yezwi wongoramba. Kana tembiricha iri ipfupi zvishoma nezvishoma, nokuti ayo iri mairi condensation mvura mhute. Sezvo makore aumba.

Huru Zviratidzo iyo munhu anogona kuona ushamwari ekunze mberi:

• plummets mumhepo kumanikidzwa;
• yakawedzera dova pfungwa ;
• zvakawedzera tembiricha;
• Kune pinnate, ipapo cirrostratus, uye pashure - soro-stratus kumakore;
• Mhepo zvokuchinjana zvishoma rworuboshwe hunosimba;
• makore ave Nimbostratus;
• kunayisa chikawira kunosiyana zvikuru.

Kazhinji, pashure kumira kunonaya zviri achidziya, asi hahugari refu, nekuti dzihwa mberi ari ichimhanya zvikuru uye ndibate pamwe inodziya ekunze mberi.

chando mberi

Pane kudaro zvakakurumbira: noushamwari mberi nguva dzose tilted yakananga inofamba, uye kutonhora - akananga kumwewo. Kana pane kwebasa fronts, mhepo inotonhora iri wedged ari kudziya, kungoita izvozvo uchikwira. Cold ratinoona fronts kutungamirira vasanyanye tembiricha uye kutonhora pamusoro ndima yakakura. Sezvo kutonhora wakamutswa inodziya mhepo vakawanda vari mushongwe mwando condenses.

Huru Zviratidzo iyo munhu anogona kuona chando mberi:

• kumanikidza pamberi pamberi inowira kunze mitsetse inowedzera zvinoshamisa;
• cumulus makore akaumba;
• pane gusty mhepo, rakapinza nokuchinja mirayiridzo iri Kutenderera divi;
• Kuchitanga rinorema mvura kana chimvuramabwe nemabhanan'ana, mvura nguva maawa anenge maviri;
• tembiricha anowa hasha, dzimwe nguva kune 10 ° C zvakananga;
• nokuti mumhepo mberi pane zvakawanda kunyatsotsanangura.

Kuti Vafambi apfuure chando mberi - muedzo hakusi nyore. Dzimwe zvakafanira kukurira eddies uye squalls mu murombo maonero ezvinhu.

occlusions

Zvakanzi kuti mumhepo fronts vakasiyana, kana pamwe kudziya uye kuchitonhora kana kusatonzwa zvose zvakajeka, ipapo pamberi occlusion zvinokonzera mibvunzo yakawanda. Paumbwe zvakadaro migumisiro kuitika munzvimbo kuvhara chando uye ushamwari fronts. Anodziya mhepo iri misha kumusoro. Huru chiito kunoitika nedutu panguva yakawanda nokukurumidza chando pamberi waparadza noushamwari. Zvinoguma kufamba uye mamiriro okunze fronts kudhumhana mhepo makore matatu, maviri chando uye mumwe kudziya.

Huru zvinhu anoratidza occluded fronts:

• makore kwakapararira kunayisa mhando;
• chimbichimbi rokuchinja mirayiridzo nemhepo pasina kuwedzera kuchinja simba;
• kwakanaka Kuchinja nevezera;
• hapana chimbichimbi tembiricha kuchinja;
• madutu.

Front occlusion kunobva tembiricha mhepo inotonhora iri pamberi pake uye mutsetse ake. Kusiyanisa pakati chando uye kudziya occluded fronts. Mamiriro ezvinhu yakaomesesa akacherechedza panguva yepakarepo pakazovharwa fronts. Sezvo mhepo inodziya misha avhiringidzwa unopinza, mamiriro ezvinhu okunze kuvandudza.

Madutu uye anticyclones

Sezvo ari rondedzero pamberi occlusion rakashandiswa rokuti "nedutu", zvakakodzera kuudza kuti mhando chinhu.

Nokuda kuti gogonera kugovera mhepo vari achiumbwa penyika akaturikidzana mukuru uye vakaderera kumanikidzwa zvikamu. kumanikidzwa mapazi ichazivikanwa noku nekumwisa mhepo, neyamapani - ayo kukwana chitsama. Somugumisiro, mhepo kubuda pakati zvikamu (zvinopfuura kukwana) mhepo aumbwa. Dutu - yakaderera kumanikidzwa mugove, izvo it sezvo fanera, mhepo uye makore vasisiri kunzvimbo vari rakawandisa.

Anticiklon - pressurized mugove iyo displaces zvakawandisa mhepo iri pasi kumanikidzwa wongoramba. The chikuru unhu - zvakajeka okunze, sezvo gore mapazi uyu kuitwa kutsiviwa.

Nzvimbo weboka ratinoona fronts

Zvichienderana okunze munyika dzine pamusoro izvo ratinoona fronts vari kuumbwa, vari akakamurwa pamusoro nenzvimbo tichishandisa:

1. Arctic kupatsanura arctic chando mhepo makore kubva zvine mwero.
2. Polar yaiva pakati unozvidzora uye Tropical vakawanda.
3. Tropical (wezvokutengeserana mhepo) delimiting ichinaya uye Tropical zvikamu.

The simba runotikurudzira pamusoro

The ehupfumi mhepo makore mumuviri sei nemwaranzi uye orudzi runotikurudzira penyika Pasi. Sezvo nehunhu pose akadaro angava akasiyana, uye kukweshera ihwo gogonera. Complex enzvimbo ruyamuro kunogona kukanganisa mumhepo mberi mutsetse uye kuchinja zvachinokonzera. Somuenzaniso, pane zviitiko apo kuparadzwa ratinoona fronts pamusoro & anooneka zvikuru nemichinjiziri.

Air makore uye mhepo yakapoteredza fronts kuunza zhinji isingatarisirwi forecasters. Achienzanisa uye kudzidza kutungamirirwa kwebasa vazhinji uye vagaries pakati madutu (anticyclones), ivo vanoumba machati uye nezvakafanotaurwa kuti vanhu vanoshandisa zuva nezuva, kunyange pasina kufunga kuti guru basa shure kwayo.
