Inotungamirwa, Secondary dzidzo uye zvikoro
US ekunze. The okunze North America - tafura. Okunze South America
Kashoma munhu angaramba kuti okunze States rakanyatsojeka siyana, uye unogona kuva saka zvinoshamisa rakasiyana chikamu rimwe nyika panorumwe, kuti dzimwe nguva, vachifamba nendege, Willy-nilly, unotanga kufunga kuti mugumo wako ari mumwe mamiriro akaraswa. Mugomo twi, yakavanzika chando nguwani, panyaya maawa ndege unogona kuwana pachako mugwenga, apo cacti vanokura, uye kunyanya makore yakaoma ingangodaro kufa nenyota kana kupisa.
Saka chii chiri okunze muUnited States yose? Chii kutarisira kubva okunze panguva dzakasiyana? Edza kunzwisisa pamwe chete.
Section 1. General mashoko
Nharaunda yakakura muUnited States vane siyana kwemamiriro okunze. Pano unogona kuwana kumatunhu pamwe zvinenge ekunze waivako zvose.
Maererano nenyanzvi, chinokosha kukanganisa US okunze ane zvose nzvimbo yomugariro imwe chikamu nyika.
Inotungamirwa pamwaka ekunze mhando mukati mapazi kunobva kwakaita nzvimbo yacho, gungwa dzenzvimbo uye zvimwewo. Nzvimbo huru wenyika, yaiva kumaodzanyemba, iri munzvimbo yacho subtropical mapazi, kuchamhembe okunze pakati America ine zvose zvinoitwa zvine mwero mhando.
Hawaii uye South Florida ndivo dzinopisa, Alaska yokusafa mamiriro okunze ari polar kumatunhu Nyika. US foothill rwenze kunoratidzwa Semi-murenje ekunze, uye California Coast - Mediterranean ekunze. Plateau Great Basin uye nharaunda yakapoteredza riri munzvimbo dzisinganayi okunze.
Zviya, kashoma kuti mumwe munhu angaramba chokwadi kuti zvakanaka mamiriro okunze kwainge guru basa nyaya ino.
Section 2. US ekunze nemamiriro ayo inotungamirwa

Masayendisiti anodavira kuti okunze enzvimbo North America (Table 1) dzaisiyana ainyanya nokuda zvinhu zvinotevera kutaurwa pazasi.
mhepo Wet diridza kumadokero kwemhenderekedzo kuUnited States. Kuchamhembe kazhinji kunonaia, uye nzvimbo idzi vane chando zvikuru muchando. In California, vakawanda kunayisa inowira mumatsutso uye chando, muzhizha zvaoma uye inopisa. naizvozvo ichaongororwa kuti okunze ari kumadokero kweUnited States kazhinji kuti kufanana nayo vatama vachibva Central Russia. The ekunze pano anenge kuchinja, sezvo mwaka kuchinja pane akajeka uye zvine musoro.
Sechipanji ose mwando Cascade uye Mountains Rocky, kuti Sierra Nevada, uye mugumisiro wacho Yaunoti mvura mumvuri, hunobata okunze ari kumadokero Papurazi Great.
Zviya, haasi munhu wose anoziva kure kuti mvura-mumvuri zvakonzerawo chidzoke Nerufu Valley uye mumarenje of Basin Great. Mune kudhumhana ndege sorukova chete mhepo dzenzvimbo muGulf of Mexico pane madutu simba uye mabhanan'ana. Zvichienderana mhepo gobvu tembiricha shanduko kunoitika. It kungawedzera kana kudukupiswa.
Section 3. Kuoma
Asi zvikuru, chokwadi, kunoenderana nzvimbo mumwe kana chimwe nyika. Somuenzaniso, okunze pakati North America (Table 1), kupisa ane zvishoma kukanganisa pane dzimwe ndima, asi richiri zvakakonzera njodzi nyika asingatani pamwero mukuru.
Somuenzaniso, kusanaya kwemvura pakati 1931 uye 1940, akadana Muguruva Bowl, akapotsa akaparadza vose mapurazi ose Papurazi Great. Dambudziko Huru kwakadaro yavewo akacherechedza muna 1999-2004.
Asi pakupedzisira kwemvura, izvo yakaitika California, chainyanya simba uye kwakakonzera kupwa kweLake Folsom, apo kungoda ndarama nenhokwe kugarwa dzakafukurwa. Mune dzimwe nzvimbo mamiriro zvashata akanzi. Dry ekunze akaita akaderedza mvura reserves mu reservoirs System State Water Project, uye vanhu vanopfuura mamiriyoni 25 vakasiyiwa pasina mvura.
Section 4. kupfuura kunoparadza dutu
Muna April gore rino pane Tupelo, Mississippi dutu ndokurova simba kuti yakauraya vanhu vanopfuura 20 vava. Chaikosha backlog nevamwe US rinoti, achiuraya okuvadza hwakawanda vanhu, akaparadza misha uye tikurukure.
Section 5 madutu muna American
Madutu - wechisikigo chakajairika, izvo kwakakurumbira munyika ino. US Climate kunoita inotungamirwa yavo.
Zvikurukuru kukanganiswa ichi njodzi nzvimbo kumabvazuva, irwo Hawaiian Islands uye kumaodzanyemba inoti inoganhurana Gulf Mexico. The dutu mwaka kunotora June kusvika December. The huru kurwadzisa kuti nguva kubva August kusvika October. The shanu madutu simba zvikuru zvinosanganisira: "Katrina", "Ike", "Wilma", "John" uye "Charlie."
Mutungamiri pakati pavo pedutu "Katrina". The chinhu pakupera August 2005 chainyanya inoparadza muna US munhoroondo. Wakaomesesa yakarova New Orleans muLouisiana. Vanopfuura 80% of nzvimbo guta vaiva pasi mvura, akauraya vanhu vanopfuura 1,800, kukuvara kubva njodzi vakasvika mabhiriyoni 125 US emadhora.
Wechishanu dutu of 2008 mwaka aiva "Ike", akagamuchira 4 pamwero wenyika ngozi "Saffir-Simpson." Dutu yarova kumaodzanyemba-kumabvazuva kwemhenderekedzo kuUnited States, mhepo kumhanya yakasvika 130? Km paawa. The kwacho of dutu raiva 1.150 km northeast weguta Wilmington (North Carolina). Damage kubva njodzi vakasvika mabhiriyoni 30 US emadhora.
Enough nyanyisa uye maturo dzinopisa dutu raiva dutu "Wilma". Muna 2005, aiva nesimba rechitanhatu uye vakauya zvakakomba kukuvara. The chikuru simba pedutu chakakonzerwa pamusoro vokuYucatán Peninsula uye Florida. Kuuraya vanhu vanenge 62 uye zvoupfumi nezvinhu vakasvika mabhiriyoni 29 US emadhora.
Section 6. Mafashamo muna US
Nzizi dzakawanda munguva nemadutu. Zvinoumba US zororo kukanganisa chitarisiko chavo. Somuenzaniso, imwe mabhanan'ana anogona kukurumidza kugutsa kanjoni uye kurera mvura revarombo. Nzizi chikonzero ave madzvotsvotsvo, nokuti izvo kazhinji kuitika Madhaka.
The guru mafashamo akaitika muna May 2011, akatambura kubva masere US inoti. The mvura dhigiri ari Mississippi River wakamutswa kakawanda, kuwedzera nokukurumidza ano. Njodzi anenge akaparadza guta New Orleans. Upamhi rwizi muna Tennessee yakawedzera 6 nguva uye zvikazara nzvimbo yakakura. Uye pamusoro pemahombekombe rwizi Cumberland kwakatungamirira nekurashikirwa neupenyu uye zvakakonzera husingagumi kukuvara zvinhu.
Section 7. kupi unowanzosangana kudengenyeka kuitika?
The nharaunda yose kumadokero kwemhenderekedzo North America rinoreva nzvimbo yainzi Pacific bhandi moto, apo pane kudengenyeka kwenyika zhinji. nzvimbo iyi kunosanganisirawo nharaunda kubva Alaska kuchamhembe California. Zvikurukuru anoputika muna Cascade Range kuchamhembe United States. Asi kuputika basa iri Hawaii, inozivikanwa ayo anoputika, hazvina ngozi vanhu.
Kwenyika rakasimba muzana remakore rapfuura zvakaitika ichangobva mu Washington. Chakamira pakunodengenyeka zvine ainzwira vanhu vanopfuura mamiriyoni 12. Akava dambiro romukondombera Virginia. Haina muchiwirirana. Asi kana kwacho yaiva mukati netsoka kubva Washington kana New York, zvaigona kunge zvikuru zvikuru. Seismologists dana asinganzwisisiki vibrations izvi uye kuwana inovhiringidza.
Section 8. Climate Change
Sezvinogona kuoneka kubva mashoko acho pamusoro, mhando okunze ari North America vari siyana zvikuru, asi hazvigoni kunzi yakatsiga. Sei? Chokwadi ndechokuti gore kubva nyanzvi yakati kuchinja pagore.
Saka, kuongorora echando crystals mumhepo zvakaratidza kuti zviri CO 2 mumhepo yakawedzera 40%. Maererano masayendisiti, izvi nokuda mabasa evanhu. Pasinei nokuti CO 2 ari constituent chinhu dzedenga, munhu kubva Zvisaririra chinotsva combustion kanganisa kwomuzvarirwo kabhoni kutenderera uye ayo pachisara nokuwa neChitatu. Zvakawandisa CO 2 kugutsikana mune ramangwana kungaita kuti kuwedzera tembiricha kwete chete mukati nyika asiwo yose pasi pose yose.
Tichienzanisa gumi adarika richisimuka yevanhu avhareji tembiricha kufambira. Asi Fani iyi hazvirevi apikise vamwe kuchinja pose tembiricha zviratidzo.
Kudziya ane madhigirii shoma kunogona kuva chikonzero chakakura atye. Kunyange diki kutsauka kunokanganisa miganhu kuchinja tembiricha uye kwemvura, uyewo kuwedzera yokunyanyisa zviitiko okunze.
