Required Textbook: Physics and Chemistry of Clouds by D. Lamb and J. Verlinde. Get it online here or at the University Book Store. Be sure to check out the errata here!

Optional/Supplementary Texts: 

  • Microphysics of Clouds and Precipitation by H. R. Pruppacher and J. D. Klett
  • A Short Course in CloudPhysics by R. R. Rogers and M. K. Yau

Note: any required readings from these optional texts will be provided. These books are available at the EMS Library. You can also download the entire PDF of Pruppacher and Klett through the university library here

Pre-requisites: METEO 431/531 (Atmospheric Thermodynamics/Thermal Physics)

Grading: Your final grade will be based on the following:

  • Midterm Exam #1 (25%)
  • Midterm Exam #2 (25%)
  • Midterm Exam #3 (25%)

Exam Policy:

I will administer the midterm exams during a special evening session, unless students are opposed to this. The idea is to give you more time than is available during the normal class period. We will determine the dates of the midterm exams within the first couple of weeks of class.

Except for illness or emergencies, make-up exams will be conducted only for students who make arrangements with me prior to the scheduled exam time. 

Problem Sets

I will be assigning problem sets ("homework") on an approximately weekly basis. These problems are for you to work through with your peers. It is up to you individually to make sure you understand the concepts! I will not collect or grade these problems. You may come to see me if you have difficulties. The exams will comprise problems similar to those on the problem sets, so it behooves you to work through and understand them! 

Final Paper

During the course, you will need to complete a final paper that delves more deeply into a topic of your choosing in cloud physics. The topic can be anything, but it must be related to clouds in the atmosphere. Topics could include: (1) Stratocumulus cloud impacts on climate; (2) Arctic clouds and climate change; (3) Turbulence influences on the growth of water drops; (4) Why ice crystals have dendritic forms; (5) The molecular nature of liquid water; (6) How ice impacts thunderstorm evolution; (7) Lake-effect snow storms; (8) Remote sensing observations of clouds, etc. Literally any topic that relates to clouds can be used. Once a topic is defined, it is up to the student to do an in-depth literature review (books or articles from journals) on the topic. This should be done during the semester. A final paper is then turned in that is 10 pages or less, not including references or figures. The paper must be either 11- or 12-point font, with double or at minimum 1.5 line spacing. Single-spaced papers will be returned ungraded. I will turn out a separate document describing the details of the project. The paper is due on the last day of class but there will be some portions due along the way to motivate progress. 

Course Objectives and Intents:

This course is designed to provide graduate students with diverse backgrounds a foundation in, and an overview of, the physics of clouds as typically found in the atmosphere. Our understanding of clouds will develop naturally through examinations of the fundamental physical processes operating across a wide variety of scales. We will place primary emphasis on microphysical properties of clouds because these ultimately determine the evolution of clouds. 

Course Topics Include:

Introduction and overview of clouds (Ch. 1); properties of water (Ch. 2); phase thermodynamics and equilibrium (Ch. 3); nucleation (Ch. 7); growth by diffusion (Ch. 8); collisional interactions and growth (Ch. 9); cloud formation and evolution (Ch. 6, 10); population effects in warm clouds (Ch. 11) and cold clouds (Ch. 12); cloud electrification and lightning (Ch 14.); microphysical modeling. These are subject to change due to time constraints and class interest. 

Prerequisites:

Students who do not meet the prerequisites after being informed in writing by the in- structor may be dis-enrolled during the first 10-day free add-drop period (Error! Hyperlink reference not valid.). If you have not completed the listed prerequisites, then promptly consult with the instructor if you have not done so already. Students who re-enroll after being dis-enrolled according to this policy are in violation of item 15 on the Student Code of Conduct (http://studentaffairs.psu.edu/conduct/codeofconduct/). 

Academic Integrity:

Academic integrity is the pursuit of scholarly activity in an open, honest, and responsible manner, and is a basic guiding principle for all academic activity in the College. As such, all are expected to act with personal integrity, respect for other students’ dignity, rights, and property, and to help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation, or deception. Such acts of dishonesty violate the fundamental ethical principles of the EMS community and compromise the worth of work completed by others. The full college policy on academic integrity can be found here.

Simply put, don’t cheat. This includes but is not limited to copying, plagiarism, self- plagiarism, etc., all of which can result in a 0 on the assignment and/or an F or XF grade in the course. Ultimately, it negatively affects you: imagine the future disappointment of employers, family, and friends when you turn out to have severe inadequacies as a cloud physicist.
