Hasken rana radiation

Very kusa da duniya star, kamar yadda ka sani, shi ne rãnã. Emits electromagnetic taguwar ruwa da ciwon daban-daban tsawo. Alal misali, wasu an gabatar a cikin nau'i na haske, da sauran - a cikin irin na infrared haskoki, samar da gwaggwabar riba zafi, da sauransu - shi ne wani rukuni na ganuwa ga mutum ido haskoki (igiyoyin rediyo, ultraviolet, X-ray).

Igiyoyin rediyo tare da wani gajeren zangon, a bayyane haske, da mafi kyau izinin tafiya a cikin yanayin duniya. Gamma-haskoki, ultraviolet da X-ray tunawa da iska daina kai hare hare. A iyakar Duniya ta yanayi tsanani daga hasken rana radiation ne m, kuma nawa to 1.35 kW / m2.

Sun ne kawai na halitta tushen haske da zafi a duniya. Yaxuwa da kuma kai tsaye radiation - da main iri hasken rana radiation. Rays wucewa ta hanyar data kasance yanayi yadudduka, dan kadan mai tsanani da su. Kai Duniya ta surface hasken rana radiation ba warwatse da kuma tunawa a cikin iska casing, kira line. A tsanani na radiation dogara a kan site latitud yankunan: sandunan da Duniya ta ekweita kwarara an rage, da tsanani da aka rage, musamman ta kara cloudiness da rage nuna gaskiya a Yanayin.

Saboda gaskiya cewa iska ya ƙunshi lafiya da ake wãtsarwa, ruwa droplets, barbashi na gishiri lu'ulu'u, da mutum haskoki samu ta hanyar hasken da fuskantar wadannan matsalolin suna warwatse. Wannan hasken rana radiation aka kira yaxuwa. Yana zama game da 25% na jimlar kwarara daga cikin tunawa haskoki. A watsar da radiation cloudless rana ne 0,07 kW / m2, m, gizagizai weather - 0.5 kW / m2. Tare da ragewa tsawo solstice, kara cloudiness, rage nuna gaskiya da yanayi qara da rabo daga wannan radiation. Nazarin ya nuna cewa a low latitudes rabo daga dabam radiation ne ma ƙananan fiye da a tsakiyar da kuma high latitudes. Kewaye halitta haske a kan wani hadari rana ne cikakken tabbacin da wadannan bim.

Total hasken rana radiation aka hada da duk kai tsaye da kuma warwatsa radiation kai Earth. Its yawan dogara a kan daban-daban dalilai, ciki har da tsawon lokaci da rana, da nuna gaskiya da kwana na abin da ya faru da kuma gajimare a cikin yanayi. Alal misali, a cikin wurare masu zafi latitudes shekara-shekara Figures total radiation na domin na 200 kcal / cm2 a iyakacin duniya zone - game da 50 kcal / cm2.

A karamin girma da hasken rana radiation tunawa da impurities da kwayoyin da yanayi gas. Lokacin da wannan radiation hits da ƙasa surface aka partially tunawa da duniya partially nuna baya cikin yanayi.

Akwai yawa cewa characterizes rabo na nuna haske ga abin da ya faru a kan Duniya ta surface - da albedo. Wannan adadi da aka bayyana a matsayin mai yawan. Ya kamata a lura da cewa albedo darajar maida hankali ne akan wani fairly fadi da kewayon da kuma dogara a kan yankin. Saboda haka, domin gandun daji da kuma steppe adadi ne game da 13%, kuma Yanã ƙãra zuwa 90% a kan sabo snow murfin. Akwai gwaji dogara da surface albedo na kwana na abin da ya faru. Lokacin da kai tsaye da hasken rana radiation kuma high tsawo rãnã da darajar wannan nuna alama - game da 3-4%, tare da low tsaye - kusan 100%. Domin warwatse radiation albedo ne game da 8-10%. A wannan yanayin, kusan babu dogara a kan tsawo na solstice.

An sani cewa hasken rana ne tushen rai a duniya, wanda yana da tasiri kai tsaye a kan jikin mutum, da thermal jihar, metabolism, aikin aiki na gabobin da kuma tsarin, da kuma more.

Daga cikin tsawo na solstice dogara da tsanani da radiation kai surface na ultraviolet. Idan tsawo na rana ne kasa da 25%, UV radiation, mafi ilimin aiki, shi ba ya isa da ƙasa.
