【摘要】：大氣和海洋界面存在復雜的相互作用,尤其在熱帶氣旋過程中,相互作用表現(xiàn)更為顯著,大氣和海洋、波浪的狀態(tài)時刻受到彼此間相互作用而發(fā)生變化,在數(shù)值模擬中需要合理反映三者之間的耦合作用。本文采用MCT(Model Coupling Toolkit)耦合器,基于大尺度大氣模型WRF、三維非結構化網(wǎng)格海洋模型FVCOM和第三代海浪模型SWAN,建立了大氣—海洋—波浪實時耦合模式,并將模式應用于理想臺風狀況下的模擬。論文的主要內容及結論為:1.利用MCT耦合器,基于WRF、FVCOM和SWAN模型建立了大氣—海洋—波浪實時耦合模式,實現(xiàn)了不同類型網(wǎng)格之間的數(shù)據(jù)插值和傳遞。三個模型間通過交換所需物理量實現(xiàn)實時耦合,WRF提供海表面風要素,FVCOM提供海表面溫度、水位和流速,SWAN提供有效波高、波長和譜峰周期等。2.將大氣—海洋—波浪實時耦合模式應用于理想熱帶氣旋情況下的模擬。對非耦合、大氣—海洋耦合、大氣—波浪耦合、以及大氣—海洋—波浪耦合等不同情況進行了模擬分析,認為海表面溫度受到熱帶氣旋作用降低,并反饋作用于臺風,使臺風強度減小。增大的海表面粗糙度也會降低熱帶氣旋的風速。
[Abstract]:There are complex interactions between atmosphere and ocean, especially in tropical cyclones. The interaction between atmosphere and ocean, the state of waves is changed by interaction with each other at all times. In the numerical simulation, it is necessary to reasonably reflect the coupling between the three. Based on the large scale atmospheric model WRF, 3D unstructured grid ocean model FVCOM and the third generation ocean wave model SWAN, a real time coupled atmospheric ocean wave model is established by using MCT (Model Coupling Toolkit) coupler. The model is applied to the simulation of ideal typhoon. The main contents and conclusions are as follows: 1. Based on the WRF,FVCOM and SWAN models, a real-time Atmospheric ocean-wave coupling model is established by using MCT coupler, and the data interpolation and transmission between different types of meshes are realized. The three models are coupled in real time by exchanging the required physical quantities. WRF provides sea surface wind elements, FVCOM provides sea surface temperature, water level and velocity, SWAN provides effective wave height, wavelength and peak period, etc. Atmospheric-oceanic-wave real-time coupling model is applied to the simulation of ideal tropical cyclones. In this paper, the uncoupled, atmospheric and ocean coupling, atmosphere wave coupling and atmosphere ocean wave coupling are simulated and analyzed. The results show that the sea surface temperature is reduced by tropical cyclones, and that the sea surface temperature is affected by typhoon. Reduce the intensity of a typhoon. Increased sea surface roughness also reduces the wind speed of tropical cyclones.
