| 摘 要： | 用Niiler—Kraus类型的混合层积分模式,对TOGA—COARE强化观测期间由《实验3号》科学考察船观测资料得到的混合层深度和SST在季节内时间尺度的变化进行了模式研究。指出:1.混合层耗散参数与较长时间尺度过程风应力的变化存在着比较好的对应关系;2.模式可以较好的对风场和热通量场在季节内时间尺度的变化作出响应,模拟出季节内时间尺度SST的变化;3.Niiler,-Kraus模式在考虑耗散作用后,可用于海洋季节内时间尺度变化的模式研究。

| Abstract: | In this paper,based on the data of SST and mixed layer depth measured by the Shiyan 3 during the TOGA-COARE IOP , we study the intraseasonal time scale variations of SST and mixed layer depth through a Niiler - Kraus type integrated mixed layer model. Our studies show that 1. there is a better correlation between the dissipation parameter and the wind speed; 2. the model is good in responding the variations of wind and heat fluxes and can simulate, to some extent, the intraseasonal time scale oscillations of SST ; 3. after adding the dissipation term, the Nuler- Kraus type model can be used to study the modelling of intraseasonal time scale variations in the upper ocean. |
