US nyengo. Nyengo ya North America - tebulo. Nyengo ya America South

Nkomwe aliyense angakane chakuti nyengo ya United States ali osiyanasiyana ndithu, ndipo mukhoza kukhala mosayembekezera osiyana kuchokera mbali ina ya dziko pa ena, nthawi zina, kuyenda pandege Willy-nilly, inu kuyamba kuganiza ngati mavuto anu ali mu chikhalidwe wina adzasiyidwa. Kuyambira nsonga mapiri, zisoti chobisika chisanu, pankhani ya maola ndege mungapeze nokha mu chipululu, kumene cacti kukula, ndipo makamaka zaka youma N'kutheka kufa ndi ludzu kapena kutentha.

Anthu ambiri molakwa kuti nyengo ya America South ndi North omwe, mwachitsanzo iwo abwerezedwa ngati galasi fano. Ndi zosaposa chinyengo ndi. Ndipotu, inu mukuona, nyengo, makamaka chimango cha Chaka, anapanga osati malinga ndi malo m'dzikoli. A mbali yaikulu mu ndondomeko ili komanso zomera m'deralo, kukhalapo kapena kusapezeka kwa mafunde ozizira ndi ofunda, kutalika kwa mapiri ndi kukhalapo kwa maganizo.

Kotero nyengo mu United States wonse? Kodi mungayembekezere nyengo nyengo zosiyana? Yesetsani kumvetsa pamodzi.

Gawo 1. General mudziwe

The gawo lalikulu la United States osiyanasiyana nyengo. Pano mukhoza kupeza madera pafupifupi ntchito zonse nyengo.

Akatswiri amanena kukhudzanso nyengo US ali malo onse Hrs wa gawo makamaka a dziko.

Mapangidwe mtundu nyengo nyengo mkati zone ndi zimadalira zimachititsa chilumbachi ndi mafunde nyanja ndi zinthu zina. M'dera yaikulu ya boma, yomwe ili kum'mwera, ili mu zone ya subtropical, kumpoto nyengo ya America ali mbali zonse za mtundu wapakatikati.

Hawaii ndi Florida South ndi kotentha, Alaska chibadidwe nyengo ya m'madera kumalo ozizira a Dziko Lapansi. US foothill yachonde amakhala ndi theka chipululu nyengo, ndi California gombe - Mediterranean nyengo. Plateau beseni Wamkulu komanso malo ozungulira izo ili mu malo nyengo louma.

Mwa njira, nkomwe aliyense angakane chakuti ndi nyengo yabwino unachita yaikulu ya kuthetsa Africa izi.

Gawo 2. nyengo US ndi mbali ya mapangidwe ake

A amadza noticeable kuchuluka kwa mpweya ali ndege mtsinje wa utuluke mpweya, kubweretsa chinyezi ku North Pacific.

Asayansi akukhulupirira kuti nyengo ya North America (Table 1) zosiyanasiyana makamaka chifukwa zinthu zotsatirazi otchulidwa pansipa.

M'madzi mphepo kuthirira kugombe la kumadzulo kwa United States. Kumpoto chakumadzulo nthawi zambiri mvula, ndi malo awa ali achisanu kwambiri yozizira. Mu California, ambiri a mvula imagwera mu yophukira ndi yozizira, m'chilimwe ndi wouma ndi kutentha. Choncho ankaona kuti nyengo ya kumadzulo United States kaŵirikaŵiri mukufuna kuti anthu ochokera ku Russia. Nyengo pano pafupifupi zikutsatiridwa, monga nyengo kusintha pali bwino ndi zomveka.

Kuyamwa chinyontho onse kugwa ndi miyala kumapiri a Sierra Nevada, ndipo chotsatira otchedwa mvula mthunzi, ndipo izi zimakhudza nyengo kumadzulo kwa Great m'Chigwa.

Mwa njira, osati aliyense amadziwa kwambiri kuti ndi mvula mthunzi kunathandiza kuti zikamera Imfa Valley ndi m'chipululu cha beseni Wamkulu. Mu kuwombana ndege mtsinje ndi mafunde mpweya wa Gulf of Mexico pali mkuntho wamphamvu ndi mabingu. Malinga ndi mpweya misa kusintha kutentha amapezeka. Mwina kuwonjezera kapena kuchepa.

Gawo 3. Chilala

Hot nyengo ndi mpweya pang'ono kwa nthawi yaitali kumabweretsa chilala, lomwe United States - chodabwitsa pafupipafupi, ndi mavuto aakulu.

Koma kwambiri, kumene, zimadalira malo amodzi kapena mbali ina ya dziko. Mwachitsanzo, nyengo ya North America (Table 1), kutentha ali zochepa amadza kuposa ena m'deralo, koma anachititsa masoka dziko sachedwa Mbali yaikulu.

Mwachitsanzo, chilala pakati pa 1931 ndi 1940, wotchedwa Fumbi Bowl, pafupifupi kuwonongedwa minda onse Wamkulu m'Chigwa. Chiwonongeko zoopsa ngati wakhalanso anati mu 1999-2004.

Koma chilala otsiriza, kumene kunachitika mu California, zinali zamphamvu kwambiri ndipo zinachititsa kuti kuyanika ndi Nyanja Folsom, kumene kuda golide liwiro kuthetsa ankagwidwa. M'madera ena a boma la mwamsangamsanga ananena. kouma kuchepetsa nkhokwe madzi mu malo System State Water Project, ndipo anthu oposa 25 miliyoni anatsala popanda madzi.

Gawo 4. mphepo yamkuntho yowononga

US amatsogolera chiwerengero cha Anthufe tikuvutika, ndiwo khalidwe la nyengo ya boma. Anthufe tikuvutika izi chifukwa zomvetsa anthu ndi chuma. The chiyerekezo cha tcheru mphepo yamkuntho siren wapadera, ndi nyumba yonse Amawapatsa pogona. chifukwa ndi mumlengalenga vortices kugunda kwa misa ofunda ndi ozizira mpweya. zambiri kuposa Anthufe tikuvutika zimachitika otchedwa mphepo yamkuntho Alley, amene akwatirana kumadera zinthuzo achilengedwe wamba.

Mu April chaka chino pa Tupelo, Mississippi mphepo yamkuntho anakantha wamphamvu amene anapha anthu oposa 20 akhala. Mchitidwe backlog ndipo limati zina US, kupha ndi kuvulaza Anthu ambiri, unawononga nyumba ndi kulankhulana.

Chigawo 5 mphepo mu American

Yamkuntho - chodabwitsa zachilengedwe, zomwe ndi wamba m'dzikoli. US nyengo amalimbikitsa mapangidwe awo.

Makamaka anakhudzidwa ndi madera izi tsoka kugombe la kum'mawa, ndi Islands Hawaii ndiponso mayiko kum'mwera kumalire ndi Gulf of Mexico. The mphepo yamkuntho nyengo chimakhala cha June kudzera December. Nkhonyayo waukulu zapakati pa August mpaka October. The asanu mphepo yamphamvu kwambiri monga: "Katrina", "Ike", "Wilma", "John" ndi "Charlie."

Mtsogoleri pakati pawo mphepo yamkuntho "Katrina". Amafotokozera kumapeto kwa August 2005 anali zowononga kwambiri m'mbiri US. Chovuta kugunda New Orleans ku Louisiana. Oposa 80% ya malo mzinda anali pansi pa madzi, anapha anthu oposa 1,800, kuwonongeka tsoka anakwana madola US 125 biliyoni.

The mphepo yamkuntho chachisanu cha nyengo 2008 anali "Ike", analandira 4 pamlingo pa choopsya "Saffir-Simpson." Mkuntho anagunda kum'mwera kum'mawa gombe la United States, liwiro mphepo anafika 130 Km paola. Pamene panayambira a mvula imene inali 1.150 Km kum'mwera chakum'mawa kwa mzinda wa Wilmington (North Carolina). Kuwononga tsoka anakwana madola US 30 biliyoni.

Zokwanira kwambiri ndi opanda pake mkuntho anali mphepo yamkuntho "Wilma". Mu 2005, inali mphamvu chimodzi ndipo anabweretsa kuwononga kwambiri. Mphamvu yaikulu ya mphepo yamkuntho ya udzafika pa Yucatán Peninsula ndi Florida. Kupha pafupifupi 62 anthu ndi zomvetsa zachuma anakwana biliyoni 29 madola US.

Gawo 6. Kusefukira mu US

kusefukira kwa madzi ambiri kumachitika nthawi mvula ya mkuntho. Features mpumulo US kusokoneza maonekedwe awo. Mwachitsanzo, mvula yamabingu mwamsanga mudzaze chigwa ndi kukweza madzi. kusefukira kwa madzi chifukwa akhale mvula, chifukwa cha zomwe kawirikawiri zimachitika kugumuka.

Chigumula lalikulu zinachitika mu May 2011, ankadwala limati US eyiti. The madzi mu Mtsinje wa Mississipi wauka kangapo, chikuwonjezereka panopa. Tsoka inawonongedwa mzinda wa New Orleans. M'lifupi mwa mtsinje Tennessee chawonjezeka nthawi 6 ndipo anasefukira yaikulu m'dera. Ndipo pa a mtsinjewo Cumberland zinachititsa kuti imfa ya moyo ndipo anamupangitsa wautali kwambiri zinthu zowonongeka.

Gawo 7. Kodi nthawi zambiri zivomezi zimachitika?

Dera lonse la kugombe la kumadzulo kwa North America akunena malo a otchedwa Pacific moto lamba, pamene pali zivomezi zambiri. Kudera limeneli mulinso malo ku Alaska kum'mwera kwa California. Kalikiliki mapiri mu kugwa manambala mu kumpoto United States. Koma ntchito chiphala chamoto, mu Hawaii, wotchuka mapiri, si owopsa kwa anthu.

Chivomezi champhamvu cha m'ma otsiriza chinachitika posachedwapa ku Washington. Inagwedezeka anamva anthu oposa 12 miliyoni. Iye anakhala panayambira ya Virginia. Iwo analibe kuwononga kwambiri. Koma ngati malo omwe inali mkati mwa ulendo ku Washington kapena New York, zotsatira zake zingakhale aakulu kwambiri. Seismologists kuitana Phokoso izi mwachinsinsi ndi kupeza vuto.

Gawo kusintha 8. Nyengo

Monga Tingaone mfundo zimene zikukambidwa pamwamba, mitundu ya nyengo mu North America ndi yosiyanasiyana, koma adzatchedwa khola. Chifukwa chiyani? mfundo ndi yakuti chaka akatswiri taonera kusintha kwakukulu pa chaka.

Choncho, maphunziro ndi timibulu ayezi mu mlengalenga asonyeza kuti zili NKHA ₂ mu mlengalenga chawonjezeka ndi 40%. Malinga ndi asayansi, ichi ndi chifukwa zochita za anthu. Ngakhale kuti NKHA ₂ n'chofunika constituent wa mlengalenga, munthu malasha mafuta kuyaka kusokoneza zachilengedwe mpweya mkombero ndi ubweya kugwa kwake Lachitatu. Owonjezera NKHA ₂ zili m'tsogolo kungachititse ndi kuwonjezeka kutentha osati m'dzikoli komanso padziko lonse lapansi lonse.

Poyerekeza ndi lomaliza khumi nyamuka mlingo wa kutentha pafupifupi mochedwa. Koma zodabwitsazi si negate kusintha zina padziko lonse mu zizindikiro kutentha.

The kutentha kwa madigiri ochepa akhoza kukhala chifukwa kwambiri Alamu. Ngakhale kupatuka yaing'ono amakhudza kusintha Kupititsa kutentha ndi mpweya, komanso kuwonjezera chiwerengero cha zochitika kwambiri nyengo.
