摘要

数值天气模型中的输运通常被解析风场限制为平流,而其他流过程的表示依赖于对其他模型的强迫或耦合。讨论了数值天气模型中的非平流传输,并用两个例子进行了说明。这些是海风和地表水流。通过修改英国气象局统一模型中现有的冷池方案,这些现象的简单模型在英国气象局的统一模型(UM)中得到了表示。这种将不同的传输过程纳入一个框架的方法可以通过增加气象、地表和地下过程之间的相互作用,促进更好地表示地球系统。

Column crossing and lateral transport in numerical weather models

Column crossing and lateral transport in numerical weather models

Transport in numerical weather models is typically restricted to advection by the resolved wind field, and representation of other flow processes relies on forcing or coupling to other models. A discussion of non-advective transport in numerical weather models is presented and illustrated using two examples. These are the sea breeze and surface water flow. Simple models of these phenomena are represented in an adapted version of the Met Office Unified Model (UM) by means of modifying the existing cold-pool scheme in the UM. This approach of incorporating different transport processes in one framework could facilitate a better representation of the Earth system, by increasing interaction between meteorological, surface and subsurface processes.

期刊介绍: Atmospheric Science Letters (ASL) is a wholly Open Access electronic journal. Its aim is to provide a fully peer reviewed publication route for new shorter contributions in the field of atmospheric and closely related sciences. Through its ability to publish shorter contributions more rapidly than conventional journals, ASL offers a framework that promotes new understanding and creates scientific debate - providing a platform for discussing scientific issues and techniques. We encourage the presentation of multi-disciplinary work and contributions that utilise ideas and techniques from parallel areas. We particularly welcome contributions that maximise the visualisation capabilities offered by a purely on-line journal. ASL welcomes papers in the fields of: Dynamical meteorology; Ocean-atmosphere systems; Climate change, variability and impacts; New or improved observations from instrumentation; Hydrometeorology; Numerical weather prediction; Data assimilation and ensemble forecasting; Physical processes of the atmosphere; Land surface-atmosphere systems.
