The recent heatwave has helped make Typhoon Soulik even more powerful as it heads towards the Korean mainland,... and the typhoon also has an unusual shape.<br />Our Kim Da-mi reports. <br /> <br />Typhoon Soulik, as well as being powerful, has a rare 'donut' shape.<br /> <br /> Typhoons generally have a spiral structure, but occasionally, a large eye forms in the middle of the typhoon, giving it the shape of a donut. <br /><br />Clouds surround the typhoon’s large, circular eye, making this donut shape visible. <br /> These so-called 'Donut Typhoons' are extremely rare, making up just one or two percent of all typhoons.<br /><br />As well as it's larger-than-normal eye, Typhoon Soulik is also more powerful than normal due to the extreme heat this summer.<br /> The sea temperature right now is around 28 degrees Celsius, two to three degrees warmer than when Typhoon Gonpas hit in 2010. <br />The high sea temperature helps the typhoon maintain its power as it moves up the peninsula.<br /> On top of that, Typhoon Cimaron, which is heading for Japan, is just as strong as the current typhoon, and is on its way to catch Typhoon Soulik. <br /> When the two storms meet, they further develop by rotating against each other in a counterclockwise direction… in a phenomenon known as the Fujiwhara Effect. <br />Fortunately weather experts say, the Korean peninsula won't be directly affected by Typhoon Cimaron, nor the Fujiwhara effect.<br />Kim Da-mi, Arirang News. <br />
