“Above the foggy strip, this white arch was shining, covering one third of the visible sky in the direction of the ship's bow,” he explains. “It was a so-called white, or fog rainbow, which appears on the fog droplets, which are much smaller then rain droplets and cause different optic effects, which is a reason of its white colour.”

The red-yellow areas in the image represent regions with high aerosol concentration that have been swept upwards in convective clouds and the blue areas are clean regions. The aerosols enter Irene along rain bands, before being wrapped into the centre ...[Read More]
