Iindlela zokubona umkhathi
Iindlela eziphambili zokubonwa kwe-atmospheric zezi: indlela yokuvakala kwe-radar ye-microwave, indlela ye-airborne okanye i-rocket sounding, ibhaluni yesandi, i-satellite sensing, kunye ne-LIDAR.Irada yeMicrowave ayikwazi ukubona amasuntswana amancinane ngenxa yokuba ii-microwaves ezithunyelwa kwiatmosfera zizimilimitha okanye iisentimitha zamaza, anobude bamaza amade kwaye azikwazi ukunxibelelana namasuntswana amancinane, ngakumbi iimolekyuli ezahlukeneyo.
Iindlela zokukhala emoyeni kunye ne-rocket zibiza kakhulu kwaye azinakubonwa ixesha elide.Nangona ixabiso leebhaluni zesandi lisezantsi, zichatshazelwa ngakumbi sisantya somoya.Ukubona okukude kwesathelayithi kunokubona umoya wehlabathi ngomyinge omkhulu usebenzisa i-radar ekwibhodi, kodwa isisombululo sesithuba siphantsi.I-Lidar isetyenziselwa ukufumana iiparamitha ze-atmospheric ngokukhupha i-laser beam kwi-atmosphere kunye nokusebenzisa intsebenziswano (ukusasaza kunye nokufunxa) phakathi kweemolekyuli ze-atmospheric okanye i-aerosols kunye ne-laser.
Ngenxa yomkhombandlela owomeleleyo, ubude obufutshane (i-micron wave) kunye nobubanzi obumxinwa bepulse yelaser, kunye novakalelo oluphezulu lwe-photodetector (ityhubhu yefotomultiplier, i-photon detector enye), i-lidar inokufezekisa ukuchaneka okuphezulu kunye nokufunyanwa kwesisombululo sexeshana se-atmospheric. iiparamitha.Ngenxa yokuchaneka kwayo okuphezulu, isisombululo esiphezulu sendawo kunye nexesha kunye nokubeka iliso okuqhubekayo, i-LIDAR ikhula ngokukhawuleza ekufumaneni i-aerosols ye-atmospheric, amafu, ukungcola komoya, ukushisa kwe-atmospheric kunye nesantya somoya.
Iindidi zeLidar ziboniswe kolu luhlu lulandelayo:

Umzobo weSchematic womgaqo we-radar yokulinganisa ifu
Umaleko wamafu: Umaleko wamafu odada emoyeni;Ukukhanya okukhutshiweyo: Umqadi odityanisiweyo wobude obuthile;I-Echo: umqondiso osasazwe ngasemva oveliswe emva kokuba ukukhutshwa kudlule kumaleko welifu;Isiseko sesipili: umgangatho olinganayo wenkqubo yeteleskopu;Into yokubona: isixhobo sombane esisetyenziselwa ukufumana isignali ye-echo ebuthathaka.
