本文介绍了一种新的鄂霍次克海水文气候学。该气候学是根据远东地区水文气象研究所（FERHRI）数据库构建的。FERHRI数据库的数据量比以前研究中使用的数据量大三到五倍，因为未发表的俄罗斯观测数据已被纳入FERHRI数据库。通过相应的质量控制方法去除数据库中的错误数据后，应用客观分析程序生成1/4°× 1/4°栅格的气候学数据。在鄂霍次克海的中间层中可以看到与以前研究相似的特征，而我们的气候学提供的值填补了以前气候学的空白。从月度气候学中可以明显看出，温度和盐度分布的演变与东库页海流和北太平洋流入的季节变化一致。我们还利用从这两层残余的最低温度水域获得的数据重建了冬季混合层和密集大陆架水的气候学。可通过网站免费获取本研究中构建的所有1°× 1°气候学版本。
This paper introduces a new hydrographic climatology of the Okhotsk Sea; this climatology was constructed from the Far Eastern Regional Hydrometeorological Research Institute (FERHRI) database. The FERHRI database has a volume of data three to five times larger than the data used in previous studies because unpublished Russian observation data have been included in the FERHRI database. After removing erroneous data from the database by pertinent quality control methods, the climatology for 1/4° × 1/4° grids is produced by applying objective analysis procedures. Features similar to those in previous studies are seen in the intermediate layers in the Okhotsk Sea, whereas our climatology provides values that fill in gaps in previous climatologies. It is obvious from the monthly climatologies that temperature and salinity distributions evolve in accordance with seasonal variations in the Eastern Sakhalin Current and inflow from the North Pacific. We also reconstructed climatologies for the winter mixed layer and dense shelf water from data obtained from the temperature minimum waters identified as the remnants of these two layers. Free access to the 1° × 1° versions of all climatologies constructed in this study is available through the website.
