Objectives of the course and intended learning outcomes (competences)Acquainting with physical processes in atmosphere: thermodynamic processes, radiation, basics of cycles of some gasses and aerosols in the atmosphere, microphysics of cloud particles and cloud physics, optical and electrical phenomena in the atmosphere.
To obtain understanding and competent knowledge to analyze and to study these processes.
Contents (Syllabus outline)Atmospheric thermodynamics: Thermodynamics of non-saturated and of saturated air, of air with droplets, phase changes. Adiabatic compression and expansion, hydrostatics and stability, method of air parcel vertical displacement, changes of stability by layer vertical displacement.
Radiation: Monochromatic emissivity and absorptivity, scattering, transfer of radiation through a medium. Solar radiation by clear sky, solar constant, extinction through the atmosphere. Long-wave infrared radiation, absorptivity of the atmosphere, greenhouse gasses, “flux emissivity”, divergence of radiation energy flow and warming/cooling of air layers and of ground.
Gasses, aerosols, cloud particles, and cloud physics: cycles of some gasses and aerosols in the atmosphere and basics of photochemistry, homogeneous and heterogeneous condensation, super cooled droplets and small ice crystals, growth with condensation and deposition, growth of drops and crystals into hydrometeors. Spectra of cloud particles and their change, precipitation intensity and radar reflectivity, showers, thunderstorms, numerical cloud models.
Optical and electrical phenomena: visibility, refraction, sky colour, refraction and diffraction on droplets and crystals, rainbow, halo, corona, gloria. Electric field by fine weather, charge separation in thunderstorms, lightning.

PrerequisitesCompleted 1 level of Meteorology with Geophysics.
Assesment methodsThe assessment consists of two parts, a theoretical exam and a practical exercises exam. The practical exercises exam (50 % of final grade) can be completed with 2 half-term exams. The theoretical exam is 50 % of final grade. The candidate successfully completes the assessment by obtaining a grade 6 (pass) to 10 (excellent) in both parts.
Methods of quality assessmentSelf-evaluation, anonymous student questionnaire.
