Chapter 1: Overview

Introduction

The Advanced Research WRF (ARW) modeling system has been in development for the past few years. The current release is Version 3, available since April 2008. The ARW is designed to be a flexible, state-of-the-art atmospheric simulation system that is portable and efficient on available parallel computing platforms. The ARW is suitable for use in a broad range of applications across scales ranging from meters to thousands of kilometers, including:

∙Idealized simulations (e.g. LES, convection, baroclinic waves)

∙Parameterization research

∙Data assimilation research

∙Forecast research

∙Real-time NWP

∙Coupled-model applications

∙Teaching

简介

Advanced Research WRF (ARW)模式系统在过去的数年中得到了发展。最近公布了第三版，从2008年4月开始可供使用。ARW是灵活的，最先进的大气模拟系统，它易移植，并且有效的应用于各种操作系统。ARW适用于从米到成千上万公里尺度的各种天气系统的模拟，它的功能包括：

∙理想化模拟（如，LES，对流，斜压波）

∙参数化研究

∙数据同化研究

∙预报研究

∙实时数值天气预报

∙耦合模式应用

∙教学

The Mesoscale and Microscale Meteorology Division of NCAR is currently maintaining and supporting a subset of the overall WRF code (Version 3) that includes:

∙WRF Software Framework (WSF)

∙Advanced Research WRF (ARW) dynamic solver, including one-way, two-way nesting and moving nest.

∙The WRF Preprocessing System (WPS)

∙WRF Variational Data Assimilation (WRF-Var) system which currently supports 3DVAR capability

∙Numerous physics packages contributed by WRF partners and the research community

∙Several graphics programs and conversion programs for other graphics tools

And these are the subjects of this document.

The WRF modeling system software is in the public domain and is freely available for community use.

NCAR的中尺度以及微尺度气象部门最近维护以及支持整个WRF（第三版）的代码的子集，其中包括：

∙WRF软件框架

∙Advanced Research WRF (ARW)动力求解方法，包括单向，双向嵌套以及移动嵌套

∙预处理系统

∙WRF多种数据同化系统（WRF-Var），该系统还支持3维同化能力

∙为WRF合作伙伴以及研究论坛提供的数值物理包.

∙一些画图程序和转换适合其他画图工具的程序

这也是本文档的主题。

This program is used primarily for real-data simulations. Its functions include 1) defining simulation domains; 2) interpolating terrestrial data (such as terrain, landuse, and soil types) to the simulation domain; and 3) degribbing and interpolating meteorological data from another model to this simulation domain. Its main features include:
