9806390LynchThese investigators propose to develop, use, and evaluate a real-time nowcast /forecast system for the Georges Bank region. The scope of the system will include physical and biological variables relevant to the circulation and target species within the USGLOBEC Northwest Atlantic program. The intent is to provide networked capability for assimilating in-situ observations (from ship, moored and drifting instruments, as well as remotely sensed observations) into simulation models to provide the best estimate of the physical and ecological state of the ocean; to utilize networkavailable atmospheric forecasts to produce a circulation forecast; to examine the implications of the forecast on the ecology; and to guide the adjustment of the experimental protocol to maximize its relevance for cruise-specific goals. The system will be built from established and emerging GLOBEC tools for simulating and hindcasting Georges Bank. Our central hypothesis is that real-time forecasts are possible for detailed coupled physical/biological phenomena, with sufficient skill to allow adjustment of the observational protocol. This will be tested in an energetic and complex multi-frontal system, in the operational context of contemporary experiments about the coupled biophysical system itself.

9806390林奇这些调查人员建议开发，使用和评估实时临近预报/预测系统的乔治银行地区。该系统的范围将包括与USGLOBEC西北大西洋方案内的环流和目标物种有关的物理和生物变量。其目的是为吸收现场观测提供联网能力（从船舶、系泊和漂流仪器以及遥感观测）转化为模拟模型，以提供海洋物理和生态状况的最佳估计;利用网络现有的大气预报来制作环流预报;审查预报对生态的影响;并指导对实验方案的调整，使其最大限度地切合具体的巡航目标。该系统将建立在现有的和新兴的GLOBEC工具，用于模拟和后报乔治银行。我们的中心假设是，实时预测是可能的详细耦合物理/生物现象，有足够的技能，允许调整的观测协议。这将在一个充满活力的和复杂的多锋系统中进行测试，在关于耦合生物物理系统本身的当代实验的操作背景下。
