Lagrangian flow in the California Undercurrent, an observation and model comparison

During the period 1992–1998, 38 isobaric RAFOS floats were deployed to sample the subsurface flow of the California Undercurrent. The deployments, released over the California continental slope west of San Francisco, have sampled robust year-round poleward subsurface flow associated with the Undercurrent most seasons and the combined inshore current and Undercurrent in winter. Two other types of flow have been seen: a region of weak flow with little net displacement just west of the California Undercurrent, and an active westward propagating eddy field. This eddy field appears to be the primary mechanism for moving floats from the Undercurrent into the ocean interior. The observations and statistics from the RAFOS floats are compared with Lagrangian estimates of particles tracked in a global high resolution ocean simulation in order to evaluate the fidelity of the model along an eastern boundary. The results show that the model reproduces the general character of the flow reasonably well, but underestimates both the mean and eddy energies by a substantial amount.     

贵为天敌的天敌

HONDA CR-V在这个市场所向披靡很久了,NISSAN奇骏环伺在侧也无法撼动它的地位。当TOYOTA终于祭出第三代RAV4,我们立该有了一场不必买入场券的决斗厮杀可看。     

BEAUTIFUL WINNER

慢跑回来整理这篇专访,恰是适宜的身心状态,因为我所访问的这位美丽女士也爱慢跑。我将《关于跑步,我想说的其实是……放在手边,村上春树和John Irving分别是我喜爱和挚爱的作家,他们也都是常年的跑者。我忽然间决定,把其他在看的书丢开优先完成这一本,然后送给她。
