In winter the isotherms extend westward and northward to the Bohai Sea from the warm core of the Bohai Straits and the cold water tongue off the Qinhuangdao spreads southeastward out, so the saddle-like isotherm pattern is formed in the middle Bohai Sea. 冬季等温线以渤海海峡暖中心向西和向北两个方向伸入渤海,而从秦皇岛外海有一冷水舌向东南方向伸展,在渤海中部海域形成“马鞍状”等温线结构。
The whole variational process can be divided into four period : the period of leaving coast of the cold water tongue; the period of semi-closing of the Northern Cold Water; the period of diminishing northwards and the period of regenerating. 大体上可分为四个阶段:冷水舌离岸期,北部冷水半封闭期,北缩消亡期和更新期。
Cold - wet tongue was appeared from 09:00 to 18:00, its height is about from 0 to 600 m. 白天从09时至18时都有冷湿舌出现,高度一般维持在0~600m之间;
⑵ Spleen-Yang Deficiency Syndrome : loose stool, aversion to cold, pale tongue, edema, abdominal distension. ⑵脾阳虚证:大便稀、畏寒、淡白舌、浮肿、腹胀。
The characteristic analysis of temperature field indicated that the distributions of central fishing ground were closely in relation to the variety of cold water front, shearing front of cold and warm water and tongue front of warm water. 温度场特征分析显示,柔鱼中心渔场分布与冷水锋面、冷暖水切变锋面和暖水舌锋的变动密切相关。
