| 摘 要： | 利用PW1979海冰热力模式，考虑渤海的地理特点和气候特征，假设渤海为薄层海洋，引入二分法求解海冰表面温度。用该地区气候平均的云量、湿度、海平面气压和风速以及附近4站的月平均气温资料作为强迫场，模拟了渤海海冰的气候变化。模拟结果与逐年的海冰级数资料具有一致的变率，表明气温对海冰年际变化有重要影响。 |
| 关 键 词： | 渤海海冰 热力模式 年际变化 数值模拟 |

| Abstract: | Based on Parkinson and Washington (1979) thermodynamic sea ice model,China Bohai Sea geography and climatology,introducing a slab ocean assumption and the bisection method for calculating the ice surface temperature,using the monthly data including total cloud cover,relative humidity,sea level pressure and wind speed,together with monthly averaged surface air temperature at 4 surrounding coastal weather stations as the forcing field,the Bohai Sea ice climatic variation are simulated.Simulated results and observed annual sea ice grades have a similar variation trend,thus proving that air temperature is a decisive factor for the inter-annual variation of Bohai Sea ice. |
| Keywords: | Bohai Sea ice thermodynamic model inter-annual variation numerical simulation |
