暖舌是指暖空气前冷区方向明显伸展的狭长形区域。暖舌通常为暖湿空气的侵袭通道，因而在降水预报中有重要参考意义。
因此，在一些天气图上，它的位置会单独标识，加拿大气象学家称之为高空暖舌。
Hence its position is indicated separately on some weather maps and it is referred to by Canadian meteorologists as a trowal.
数值实验结果表明：西暖舌是由黄海暖流形成的，而黄海暖流由于冬季季风海流的补偿作用而得到加强。
Numerical experiments based on POM are carried out to study the forming mechanism of this thermal structure and its relation to the Yellow Sea Warm Current (YSWC).
