REGARDING the visitor from the southeast who blew in yesterday - was Koryn a he or a she? Time was when this sort of atmospheric calamity always carried a female moniker - Peggy, Laura, Bertha, Nancy and the like. Possibly, my old English teacher, one of nature's bachelors, had the best explanation: ''They are named quite correctly after women because one is never sure what to expect until they strike, they always cause chaos when they do and they leave a trail ofdestruction in their wake''. But then the politically-correct brigade got in on the act and campaigned for typhoons to be named after men as well. So yesterday we had Typhoon Koryn - but what gender did it represent? To get clarification, we even called the International Weather Bureau in Hawaii, which has the task of giving a name to each successive typhoon, but the office appeared to be closed (perhaps, whenever a Signal No 8 is hoisted anywhere in the world they take a holiday, too). Maybe, Koryn is the first unisex typhoon!
