Kuyini Izinga Lokushisa?
Ukushisa kuyisilinganiso esiyisisekelo sesimo samandla semvelo futhi sithonywa kakhulu yimisebe yelanga.
Ukushisa kulula ukukala futhi kusetshenziswe, kanye nemvula yendawo, ukuthola ukuthi yiziphi izitshalo ezizokhula kahle kulowo ndawo. Kodwa-ke, imingcele yokushisa efana namazinga okushisa ajwayelekile nsuku zonke nonyaka, izinga lokushisa elincane nelingenani eliphakeme, ububanzi obuhle kanye nobusuku (ubusuku nemini) kufanele bucatshangelwe ukuthi isitshalo sizokhula kanjani kule ndawo.
Ukushisa kunomthelela oqondile kuzo zonke izinhlobo zokuphila emhlabeni. Kudala induduzo yabantu noma ukunganaki (nesidingo sokushisa noma ukupholisa), sinquma izimpendulo zezitshalo nezilwane, ukutholakala kwezinambuzane nezifo kanye namazinga okushisa nokuphefumula (ukulahlekelwa komswakama ngamaqabunga).
Izinga Lokushisa Liinganiselwe Kanjani?
Ukushisa okusetshenziselwa ukukhula kwezitshalo kanye nokulima kubalwa njengokushisa kwomoya. Lokhu kulinganiswa ngaphakathi kwezindlu zokuhlala ezibizwa ngokuthi uStevenson izikrini noma izihlangu zemisebe yomoya. Lezi zindawo zokuhlala zifakwa 2 m ngaphezulu komhlaba, eduze nezinga lamaqabunga ezitshalo.
Ukushisa komoya kungase kuhluke ngokushisa komhlabathi. Ebusuku ebusika, izinga lokushisa lomhlabathi liphansi kakhulu kunezinga lokushisa kwesikrini. Lokhu kungabangela iqhwa nanobe izibikezelo zokushisa azizange zibikezele ukushisa kwamazinga okushisa emoyeni. Kodwa-ke, izinga lokushisa lomhlabathi lingase lifudumele kunokushisa kwemoya emini ngokuya ngohlobo lwendawo.
Ukushisa kwemoya evulekile kungase kube nokushisa kunokushisa kwesikrini, ikakhulukazi ehlobo.
Ukushisa kwamaqabunga avuliwe elangeni ngokuvamile ku-3 - 4ºC ngaphezulu kunezinga lokushisa elilinganiselwe (isikrini). Umehluko wehlisa cishe ku-1 ºC ngaphansi kwezimo ezithuthukile futhi uma izinga lokushisa lidlula ku-33ºC.
Amaqabunga amancane angenawo amaqabunga angaba yi-10 kuya ku-15ºC okushisa kunezinga lokushisa lomoya.
Indlela Yokuguqula i-Celsius kuya ku-Fahrenheit
ENingizimu Afrika, izinga lokushisa lilinganiselwa ku-degrees Celsius (ºC). Amanzi aqhwaza ngo-0ºC namathumba ku-100ºC (elwandle).
Ebusweni lwase-USA kusabikwa ngo-degrees Fahrenheit. Ezingeni le-Fahrenheit, iphuzu lokuqhwa kwamanzi lingama-32ºF nendawo yokubilisa e-212ºF.
