11月6日沙田道風山的山火出現了不少小型幼長的熱氣旋, 但因攝影地點距離火場較遠, 800mm焦距再crop圖能看得較清楚和結構明顯些.
算不算是 fire twister, 或是fire whirl?

"twister" should refer to a primary tornado which come into contact with a burning source and the gusty wind carried the burning fuel/substance with the burning fire.

"whirl" maybe more appropriate as the twisting is caused by the high heat generated by the fire itself (instead of an independent tornado) that somehow influenced the prevailing wind and causing twisting look by uprising burning debris.
