Feem ntau nyob rau hauv lub hnub, thaum cov dej khov los yog Frost tsis tuab heev, nws yuav yaj sai sai. Muaj cov dej ntws ntawm cov ntaub hauv qab ntawm cov khoom siv dag zog, thiab cov daus yuav raug tso tawm los ntawm cov dej ntws tom qab yaj. Thaum kawg, tsuas yog yuav tsum tau ua tib zoo saib xyuas cov av ntawm cov kwj deg thiab cov dej ntws.
Chemical snow yaj
Yog tias cov dej khov yog tuab, cov tshuaj siv tau los yaj nws. Tshaj li 100 phaus ntawm urea ib 3,000 square feet (kho tau rau ntau qhov xwm txheej thiab thaj chaw).
