Temperature and salinity outputs from ECCO (years 93-09) and GLORYS (years 03-09) models have been used to compute the thermohaline and steric sea level trends in the surface (0-150 m), intermediate (150 m-600 m), and deep (600 m-bottom) layers of the Mediterranean Sea. Some changes with respect to the second half of the 20th century have been observed: the cooling of the upper waters of the entire eastern basin since 1950 seems to have vanished; the warming of WMDW historically reported for the second half of the last century could have reversed, although there is no agreement between both models at this point (trends of different sign are predicted); the salinification of WMDW reported for the previous decades is not observed in the south-westernmost area in the period 93-09, and a clear change from positive to negative in the steric sea level trend with respect to the period 93-05 is detected due to the sharp decreasing steric sea level of years 02-06.
欧洲海洋生物地球化学与生态系统动力学实验(ECCO,93 - 09年)和全球海洋多尺度观测集合(GLORYS,03 - 09年)模型的温度和盐度输出数据,已被用于计算地中海表层(0 - 150米)、中层(150米 - 600米)和深层(600米 - 海底)的热比容盐度和比容海平面变化趋势。已观测到一些相对于20世纪后半叶的变化:自1950年以来整个东盆地上层水体的降温似乎已经消失;历史上报道的上世纪后半叶西地中海深层水(WMDW)的升温可能已经逆转,尽管此时两个模型之间尚无定论(预测出不同符号的趋势);在93 - 09年期间,最西南区域未观测到前几十年报道的WMDW盐化现象,并且由于02 - 06年比容海平面急剧下降,检测到相对于93 - 05年期间比容海平面趋势从正到负的明显变化。
