Solar Halo

A Solar Halo at Half Moon Island in Antarctica.
One of the joys of returning to Antarctica for the 13th time is more deeply explore phenomena that have intrigued me in the past. Of course I love the ice and can’t ever get enough but there are so many unique things about Antarctica that beg for further visually exploration. There are so many unique weather events on Antarctica. From Orographic Precipitation and Katabatic winds, this continent offers visuals like no other. On one trip we actually witnessed Katabatic winds blowing so hard that water from a waterfall not only never hit the ground but it reversed direction and the waterfall defied gravity.

The air in Antarctica is frequently very dry. The low temperatures mean that little or no water vapour is held in the air, instead it freezes and falls out, or builds up on surfaces as frost. Sometimes however depending on the particular atmospheric conditions, the frozen water vapour remains in the air as suspended ice crystals. In these conditions the crystals can reflect sunlight in a variety of ways forming atmospheric phenomena of different types. One weather condition I hope to have the privilege to experience again is that of a Solar Halo.

In this  case, ice crystals reflect a circle or halo around the sun and sometimes there appears to be parts of other circles touching the main circle at the 12, 3, 6 and 9 o’clock positions, these cause brighter spots which are known as sun dogs.
If you haven’t been to Antarctica consider the learning experience of a true photographic workshop and not a photo tour. For more info
