摘要
中国于2012年在北欧海的罗弗敦海盆布放了一套海气耦合浮标,断断续续地工作了三年。本文对数据质量进行了全面评估,并以2014年6月—2015年1月的数据为例,给出了该海域各参数的变化特点。经与ERA5数据对比,气压、气温、湿度、风速、水温、辐射、热通量、波浪的参数可靠,与ERA5差别较大的是风向,本文的分析认为,浮标的风向是可靠的。由此得出,除了数据明显异常的时段之外,浮标的数据质量可靠,可以直接用于研究使用。有些参数未见明显异常,但仍可存在数据漂移和数据偏差等问题,需要在使用时精心分析和判断。罗弗敦海盆夏季海表面气压高,风速小,气温高,湿度大,感热和潜热都很小;冬季气压降低,气旋数目增多,强度变大,风速增大,降温过程频繁,降温幅度和持续时间都更大,感热和潜热增大,高热通量事件出现的次数增多,持续时间更长,对大气过程产生不可低估的影响。
In 2012,China conducted an air-sea coupled buoy measurements in the Lofton Basin in Nordic Seas,the buoy worked on and off for three years.Given that this was the only buoy observation in the area so far,and the data obtained from the buoy is extremely valuable,a comprehensive evaluation of the data is provided in this paper.The comparison with ERA5 data shows that the parameter of sea surface pressure,air temperature,relative humidity,wind speed,sea surface temperature,heat flux and wave data are very reliable.The main difference with ERA5 is wind direction,the analysis suggest that the wind direction of the buoy is reasonable,and it can be used for research.Undoubtedly,there may exist data drift and deviation in some parameters even though they had no obvious abnormality,careful analysis and judgment are required in use.Take the data in the time period June 2014 to January 2015,this paper presents the variation characteristics of the parameters in Lofton Basin:in summer,wind speed is low,sea surface pressure,air temperature and relative humidity are high,sensible and latent heat flux are very small;in winter,the pressure decreases,wind speed,the number and intensity of cyclones increase,and the cooling process becomes frequent and lasts longer,sensible and latent heat flux are increased,the number of high heat flux events increase and last longer,their impact on atmospheric processes cannot be underestimated.
