Master’s Programme in Atmospheric Sciences is responsible for the course.

Module where the course belongs to:

  • ATM300 Advanced Studies in Atmospheric Sciences
    Compulsory for:
    1. Study Track in Meteorology

The course is available to students from other degree programmes.

Thermodynamics: Suitable courses at the University of Helsinki are Atmospheric Thermodynamics (53604)

If you are interested in learning how cloud and precipitation processes are studied you can attend ATM323 Advanced Course in Radar Meteorology

  • You will learn how clouds work and how cloud droplets and ice crystals form and grow
  • You will understand how ice crystals evolve into diverse shapes and what a snowflake can tell about clouds above
  • You will also learn how precipitation develops in warm and colds clouds
  • Modern cloud and precipitation observation methods will also be introduced

Can be taken in the early or later stages of studies.

The course is given every year in the spring term.

  • Brief overview of thermodynamics and cloud macrophysics (cooling mechanisms, mixing and stability)
  • Cloud microphysics, formation of the liquid and solid phase, vapor-growth of liquid drops and ice crystals, growth by collection
  • Warm Clouds, evolution of supersaturation and precipitation formation
  • Cold Clouds, ice initiation, glaciation, secondary ice production, snow and cold rain
  • Weather modification and cloud seeding, a brief introduction to aerosol-cloud interactions
  • Representation of clouds in numerical weather prediction models
  • Observations of clouds and precipitation
