In semideserts gaari Hemisphere Northern ee Utah ee loolka 16-18 °, si dhow ula kulan si Lake Chad iyo sonkor granulated. Boundary of zone ee PC ee koonfur waa Tropic of Capricorn. bannaankii Savannah mashquulin meel bannaan oo ku kici si height a badan gudahood banka Bariga Afrika.

Noocyada dega cimilada - sub-Equatorial iyo kulaylaha. Ma si cad u garan oo dhan sanadkii labadii xilli ciyaareed - qoyan iyo qalalan. xilli-roobaadka waa la dhimay marka ka dhulbaraha in kulaale iska gudbayo 7-9 ilaa 3-4 bilood. Bishii Janaayo, marka ay tahay xilli qoyan ee Northern Hemisphere ee, ee oomanaha ah ee Koonfurta bilaabmaa.

Waa maxay nooca ciidda ee savanna waxaa la aasaasay ee cimilada noocan oo kale ah? In xilli-roobaadka, nafaqooyinka yihiin culus lagu maydhay biyo ee jahooyinka hoose. Marka waa xilli qalalan, waxaa jira arrin ka soo horjeeda - xal ciidda baxdo.

nooca Dhirta iyo cimilada

Kadib markii ay helaan qoyaanka, tropical kaynta-steppe ee Africa nool. midabo Yellow-brown caws qalalan waxaa lagu bedelay cagaaran sumurud. Grow caleemaha on geedaha iyo duurka, oo hoos u caleemo in times of abaarta, cawska si degdeg ah u taagay, oo mararka qaar lagu gaarey 3 mitir ee height. Ciida iyo dhirta iyo ugaarta ee Utah ee Africa waxaa la aasaasay sarkhaansan yihiin cimilada. xaaladaha heerkulka iyo qoyaan ku xiran tahay meesha deegaanka juqraafiyeed.

U dhaw in ay ku laayeen ee xilli roobaadka, asked qiyaastii 9 bilood. Waxaa la aasaasay dheer-Utah; kooxaha geedaha iyo ku xoortay geedihii Tiro badan.

Sida meel fog ka dhulbaraha oo u dhaw in ay kulaale inta lagu guda jiro xilli-roobaadka waa la dhimay, horumarinta Utah caadiga ah. Border qoyaan deegaanka semi-cidla ah uu helo 3 bilood sano ah. Daaqa, kaas oo la sameeyay xaaladaha qalalan, waxaa loola jeedaa Utah nooca lamadegaanka. At 50 ° C, waxa ka duwan in yar oo cidlada. quruumaha North African yeedhay meelaha dabiiciga ah "Sahel", dadka reer Koonfur Afrika - "baadiyaha".

Maxaa carradu intaba ee Utah ee

noocyada kala duwan ee ciidda

Muddo aagga audio dhaco roobab dabiici ah oo kala duwan ku kala duwan yihiin xilliyada muddo qalalan. Tilmaamo dhul iyo cimilada tago Calaamad nooca Dhirta savanna. Carradu loo sameeyay by dhexgalka ee dhamaan qaybaha dhismaha dabiiciga ah. Tusaale ahaan, warshadda ayaa weli ku jira kaymaha qoyan aadan waqtiga cawisa leeyihiin, nafaqada waxaa iska dhaqday by roobab culus.

Marka la barbar dhigo carradu kaynta ferrallitic casaanka iyo jaalaha ee suunka Equatorial in savannas uruursado humus dheeraad ah. Thanks to muddada qalalan ee kala daatay la'ahay ku harta dhirta iyo humus. nooca Dhexe - muhashada ferralitic cas kaymaha variable-qoyan. Under cereals savannas waxaa intooda badan ku yaalaan carradu lateritic iyo guduud-brown. Under noocan ah deegaanka dabiiciga ah qalalan sameeyay ciidda madow. Sida aan u dhowaan gobollada lamadegaanka, waxay bedelay a carradu mid guduudan oo brown. brownish Bright ama midabka leben-cas noqdo dhul ay sabab u raasamaal ee atammada bir ah.
