A unique phenomenon in the sky 天空異象

It's a rare occasion to see such an azure sky above Kaohsiung City.
It was caused by daylong strong winds blowing from the ocean rapidly blowing away the suspending air-pollutants in the air.
A should-be normal condition has become a unique phenomenon, thus worthy of taking a picture for remembering.
But, be aware of the strong ultraviolet!

罕見高雄市有這麼湛藍的天空.
鎮日的強烈海風迅速吹走空氣中的懸浮污染物,使天空變得如此清澈.
本應是尋常的狀況,如今已成異象,所以值得拍照留念.
不過,慎防強烈的紫外線!
