actually form a circle that you can see in a plane with the right conditions．

Calhoun says．And another key is to face the rain and have your back to the sun．
5．________“Small showers and storms often form in late afternoon in this area，”Calhoun says．“These
types of showers often produce heavy rain, but remain isolated(孤立的) over the center of the island．”
