Laboratory course in numerical meteorology (5 op)

General information on NumLab courses

For remote students: see section Remote participation

Laboratory courses in numerical meteorology (NumLab) aim to familiarize students with some actual topic associated with numerical meteorology or its applications. The courses also function as an introduction to scientific working methods, and they give practice in writing of research reports and in team work.

NumLab courses have no final exam. The acceptance of the students is based on active participation (as documented in a time use diary) and on the final report written from the course projects.

Traditionally, only students who have got the course Numerical Meteorology I accepted have been allowed to enter NumLab courses. However, this rule has turned out to be too inflexible in some cases (e.g., for students from geophysics). Thus, if you don't have Numerical Meteorology I done, you may still be allowed to attend the course depending on other experience from numerics and data processing (e.g., Scientific computing I-II). This will be addressed on a case-by-case basis.

Students at University of Helsinki may include up to three NumLab courses in their MSc degree in meteorology. However, if the number of qualified local participants is too large (more than about 20), priority will be given to those attending their first NumLab.


The topic of Numlab2013 was MUSC, a comprehensive single-column atmospheric model. See the section for
Model documentation for more information.
