| 摘 要： | 根据Ｋｕｌｌｅｎｂｅｒｇ的半理论半经验公式，利用渤海中部８号平台的观测资料，选择强风期的２月和弱风期的７月分别代表冬季和夏季，推算了渤海中部海域冬、夏两季的铅直扩散系数。计算结果表明：Ｋｚ值在强风期的２月最大可达５．５ｃｍ２／ｓ；在弱风期的７月跃层中可达０．０２～０．０４ｃｍ２／ｓ。

| Abstract: | On the basis of Kullenberg's semiemperical formula, the values of the in situ vertical diffusion coefficent Kz under strong winds and weak winds are calculated in this paper by using the observed data from the platform "Bozhong 8" located in the central part of the Bobal Sea. February and July were chosen to be the typical months for winter and summer respectively. The esults show that the maximun Kz during strong winds in February is up to 5. 5cm2/s and reaches its minimum where thermoclines occur in July in the range of 0. 02-0. 04cm2/s due to stratification. |
