kohara (angreji:faug) praay: thandi aardr hava mein banta hai aur iske astitv mein aane ki prakriya baadalon jaisi hi hoti hai. garm hava ki apeksha thandi hava adhik nami lene mein saksham hoti hai aur vaashpan ke dvaara yeh nami grahan karti hai.[1] ye vah baadal hota hai jo bhoomi ke nikat banta hai. yaani ek baadal ka vah bhaag jo bhoomi ke oopar hava mein thahara hua ho kohara naheen hota balki baadal ka vah bhaag jo oopari bhoomi ke sampark mein aata hai, kohara kahalaata hai. iske atirikt kohara kai anya tareekon se bhi banta hai. lekin adhikaansh kohare do shreniyon, edavekshan faug aur rediyeshan faug mein badal jaate hain. donon hi prakaar mein kohara aam hava se adhik thanda mahasoos hota hai. aisa usamein bhari hui nami ke kanon ke kaaran hota hai.

sadak par halka kohara drushyata ka hraas karta hai. cycle chaalak 200mi/(219 gaj) par bahut hi dhundhala dikh raha hai. yahaan ki kul drushyata 400mi.(437 gaj) hai, jo sadak ke doosare chhor se bahut pehle hai.
sain Francisco ke golden gate setu par sadak ek chinh bhi dikhne mushkil hain

edavekshan faug tab banta hai jab garm hava ka ek vishesh hissa kisi nam pradesh ke oopar pahunchata hai. kai baar kohara kaafi ghana bhi hota hai jisse door dekhne mein pareshaani mahasoos hoti hai. samudra kinaare rahane vaale log edavekshan faug se parichit hote hain.

rediyeshan faug tab banta hai jab dharati ki oopari parat thandi hoti hai. aisa praay: shaam ke samay hota hai. dharati ki oopari parat thandi hone ke saath hi hava bhi thandi ho jaati hai, jis kaaran kohara upajata hai.

kohara kai pahaadi ghaatiyon mein bhi chhaata hai. vahaan oopari garm hava thandi hava ko jameen ke nikat rakhati hai. aisa kohara praay: subah ke samay hota hai. sooraj nikalne ke baad thandi hava garm hoti hai aur oopar uthati hai. iske baad se kohara chhantana shuroo ho jaata hai.
