课程名称：全球变暖 II：在 Python 中创建您自己的模型 课程概述：本课程提供一系列 Python 编程练习，旨在探索数值建模在地球系统和气候科学中的应用。与之相关的科学背景将在另一门课程“全球变暖 I：气候变化的科学与建模”中介绍。该课程假设您是 Python 编程的新手（这也是学习 Python 的好方法！），但您应该能够通过其他课程或在线教程掌握 Python 语法的基础知识。 课程大纲： 1. **时间依赖的能量平衡模型**： 本部分旨在补充 Coursera 课程“全球变暖 I：气候变化的科学与建模”，该课程介绍了许多相关背景。在这一部分，您将使用电子表格（可能）和 Python（肯定）进行一些关于地球系统科学主题的简单数值计算。本周的模型基于该课程的第三单元“首个气候模型”。 2. **迭代型失控冰-反照反馈模型**： 本模型的思想在本课程第一部分的第七单元“反馈”中进行了说明。首先，我们将生成关于行星反照率和冰形成纬度（更冷 = 更低纬度的冰）的简单线性“参数化”函数。其次，对于给定的太阳常数 L，我们将使用迭代方法找到一致的反照率和值 T，以展示冰反照反馈对地球温度的影响，导致其进入可怕的“雪球地球”。 3. **冰盖动态**： 冰块像超厚的糖浆一样向下流动。冰盖的形状（高度与横向距离的关系）由冰的表面坡度与冰流速之间的关系决定。 4. **压力、旋转与流体流动**： 行星的旋转和流体流动在本课程的第一部分第六单元“天气与气候”中进行了说明。 5. **当今气候变化模型**： 本模型的背景信息在本课程第一部分的第九单元“扰动碳循环”中进行了介绍。 通过本课程，学员们将有机会深入了解气候模型的构建，掌握相关的 Python 编程技能，并提高对全球变暖科学的认识。
Part: 1
Title:Time-Dependent Energy Balance Model
Description:This class is intended to complement a Coursera class called Global Warming I: The Science and Modeling of Climate Change, which presents much of the background to the material here. In this class you'll be using spreadsheets (maybe) and Python (definitely) to do some simple numerical calculations on topics in Earth System Science. The model you'll be working on this week is based on material from Unit 3 of that class, called First Climate Model.
Part: 2
Title:Iterative Runaway Ice-Albedo Feedback Model
Description:The ideas behind this model were explained in Unit 7, Feedbacks, in Part I of this class. First we get to generate simple linear "parameterization" functions of planetary albedo and the latitude to which ice forms (colder = lower latitude ice). Second, for any given value of the solar constant, L, we'll use iteration to find consistent values of albedo and T, to show the effect of the ice albedo feedback on Earth's temperature, running away to fall into the dreaded "snowball Earth".
Part: 3
Title:Ice Sheet Dynamics
Description:Ice flows like extra-thick molasses, downhill. The shape of the ice sheet (altitude versus distance across) is determined by the relationship between ice surface slope and the flow rate of the ice.
Part: 4
Title:Pressure, Rotation, and Fluid Flow
Description:Planetary rotation and fluid flow were explained in Part I of this class, Unit 6, on Weather and Climate.
Part: 5
Title:A Model of Climate Changes Today
Description:Background for this model was presented in Part I of this class, Unit 9, The Perturbed Carbon Cycle.
This class provides a series of Python programming exercises intended to explore the use of numerical modeling in the Earth system and climate sciences. The scientific background for these models is presented in a companion class, Global Warming I: The Science and Modeling of Climate Change. This class assumes that you are new to Python programming (and this is indeed a great way to learn Python!), but that you will be able to pick up an elementary knowledge of Python syntax from another class or from on-line tutorials.
