Chapter 8: 1, 2, 5.

There are a number of errors and typos in the text book. Errata can be downloaded here

On Monday 23 March the regular lecture will be replaced by questions (by you) and answers in advance of the mid-term exam on Wednesday 25 March

There will be no lecture on Monday 16 March because of the Ph.D. defence by Camilla W. Stjern, which you are invited to attend (see separate announcement)!

There will be no classes on 2 or 6 March due to the HPC FORTRAN course by Anne Fouilloux which runs from 9 to 12 every morning that week.

The final (oral) exam this semester is tentatively scheduled for Thursday 28 May. 

Let me know immediately if this is a problem for you.

Clouds consist of moist air and particles of condensed water, either in the liquid or solid state. Here, consider an idealized, but nevertheless "typical" cloud that contains only liquid water droplets of uniform radius r_d=15 micrometers. The droplet number concentration is n_d=100 cm^-3, the temperature T=0C, and the pressure p=600 hPa. Calculate the following cloud properties:

a) The approximate distance between the centers of the droplets. How many droplet radii does this spacing represent? (It is sufficient to assume that the drops are uniformly spaced for this problem.)

b) What is the "volume fraction" of liquid water in the cloudy air? (i.e., What fraction of any given volume of the cloudy air, say 1 m³, is occupied by the liquid drops?). What is the dominant phase of the cloud (by volume)?

c) The "liquid water concentration" w_L of the cloud, in units of g m^-3.

The first lecture this semester will be given on Monday 19 January at 10:15-12:00 in Glasshallen 2.

We will use selected parts of the textbook "Physics and Chemistry of Clouds" by Dennis Lamb and Johannes Verlinde, Cambridge University Press, 2011, ISBN 978-0-521-89910-9.

Monday 19 January: Chapter 1 (repetition, introduction) + sub-chapter 2.1.4 (aerosols).

Friday 23 January: Problem 1.2 + sub-chapters 3.2-3.3 (moist thermodynamics)

More details to follow.

Lectures will be held in Glasshallen 2, Ciens

Attendance at the first lecture is compulsory. Students who fail to meet, are considered to have withdrawn from the course unless they have previously given notice to the Studies administration, E-mail address: studieinfo@geo.uio.no.
