When drafted for military service, they were all sent to work as weather forecasters at the meteorological center of the armed forces. Jen Li-yu gained admission to the navy's meteorological center, and every day he predicted the weather as well as the velocity of the prevailing winds and the strength of the waves for the benefit of all military vessels.
因此他們一畢業，就成了台灣社會上有史以來人數最多的「氣象人才」，當兵時都一起到軍方的氣象中心去做預報工作。當時的任立渝進入海軍氣象中心，每天預報海面風浪，提供軍艦參考。
