 on the sea surface,first it takes on red bend,then it turns to purple and then it changes frequently which is hard to tell the truth and falsehood.
 The coming of mirage is because of the temperature difference between the sea surface air and the higher place air.There are two kinds:One is uprising scene.When the upper air temperature is higher than the surface temperature,the scene is like castles in the air;another is downhill scene.When the sea surface air temperature is higher then the upper air temperature,the scene is like inverted image.This year on August 29th the uprising scene appeared at the same time which was not seen once in a hundred years.
