摘要(Abstract):
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。
