Isixeko saseBeijing (China)
Kumaxesha akutshanje kukho amazwe aliqela anezixeko eziphefumla umoya ongcolileyo. I-Barcelona okanye iMadrid zezinye zazo, kodwa imeko yase China iyothusa: ngokwe-World Health Organisation (WMO), nyaka ngamnye abantu abayi-1,6 yezigidi babulawa zizinto ezinxulumene nongcoliseko.
Okumangalisayo kukuba umgangatho womoya kweli candelo lomhlaba umiselwa luthuli lwasentlango yeGobi, njengoko kutyhilwe liqela labaphandi abavela kwiLabhoratri yeSizwe yePacific Northwest (PNNL, ngesifinyezo sayo ngesiNgesi) kunye neZiko leScripps yeOrografia kwiYunivesithi yaseCalifornia eSan Diego.
Ukwenzela yena kufunda, ebipapashwe kwijenali »Indalo», izazinzulu zidibanisa idatha yezembali kunye neemodeli zekhompyuter. Ngokuhlalutya iziphumo bakwazi ukufumanisa oko ukuncitshiswa kothuli lwendalo oluhanjiswa ukusuka entlango yeGobi kumbindi nakumantla e-China kubangela ukwanda komsi kwimpuma ye-China.
Kubonakala ngathi, uthuli lwasentlango lunceda ukuphazamisa ukukhanya kwelanga. Ukuba kukho amasuntswana ambalwa, umhlaba ushushu kunesiqhelo kwaye amanzi ayabanda, anciphisa umahluko kubushushu basebusika phakathi kolwandle nomhlaba. Oku kwenza ukuba umoya uvuthe ngamandla amancinci, ngoko ke umoya "umile".
Nangona oku kuncitshiswa kuphela kweekhilomitha ezili-0,16 ngeyure, olu tshintsho inefuthe elikhulu kwimozulu kunye nomgangatho womoya kwimpuma ye China. E-Beijing bebesilwa imfazwe nongcoliseko iminyaka emithathu ngoku.
Olu luphononongo olunomdla kakhulu, hayi kuphela ilizwe lasempuma, kodwa nabo bonke abo bachaphazeleka ludaka lwe-anthropogenic, kuba ibonisa ukuba yonke into ixhunyiwe, ngandlela thile.
Umsi yingxaki enzulu ekufuneka bonke oorhulumente bayithathele ingqalelo ukuze abemi baqhubeke nokuphefumla umoya ococekileyo.
