Description:
COURSE OBJECTIVES:
To enable students that, on the basis of familiarizing with the physical processes and, in particular, measurements of the bottom (surface) layer of the atmospheric boundary layer (ABL), they can define, calculate and explain the motion of the air and exchange of energy/matter in the ABL surface layer.
COURSE CONTENT:
On weekly basis:
(1) Introduction to micrometeorology.
(2) Vertical structure and diurnal cycles of the ABL. Characteristics of statically unstable, neutral and stable ABLs.
(3) Exchange of energy and matter in the surface layer of the ABL.
(4) Statistical description of turbulence.
(5) Equations for the turbulent motion.
(6) Forms of prognostic equations for turbulent kinetic energy, turbulent fluxes and concentration of the substance.
(7) Applications of Taylor's hypothesis on "frozen turbulence" and the similarity theory in the ABL surface layer.
(8) Prognostic equations and closure techniques.
(9) Basis of micrometeorological measurements: sampling rate, record length and data quality control.
(10) In situ measurement systems for turbulent flows: meteorological flux-tower and aircraft measurements.
(11) "Eddy covariance" method for measurement of turbulent fluxes.
(12) Measurements of turbulent flow over flat homogeneous terrain.
(13) Analysis of turbulence over flat homogeneous terrain.
(14) Measurements of turbulent flow over complex terrain.
(15) Analysis of turbulence over complex terrain.
LEARNING OUTCOMES:
It is expected that students will be able to:
(1) define physical processes relevant to the movement of air and/or exchange of energy/matter in the ABL surface layer,
(2) mathematically formulate the above mentioned physical processes,
(3) measure relevant variables/parameters that describe the current state and changes of physical processes,
(4) calculate (quantify) physical processes and their changes based on measurements and mathematical formulations,
(5) analyze spatial and temporal distributions of obtained values that describe the current state and changes of physical processes, and
(6) explain what calculated and analyzed values mean for current and/or future physical state of the observed part of the ABL surface layer.
LEARNING MODE:
Attending teaching of the theory and exercises, studying of the literature and notes, deriving equations and analysis of the examples, independently solving problems.
TEACHING METHODS:
Theory, exercises, encouraging students to explore the literature by themselves, solving
the problems independently.
METHODS OF MONITORING AND VERIFICATION:
The progress of students is monitored and evaluated during the course (homework, oral presentations and other assignments) and on the final oral exam.
TERMS FOR RECEIVING THE SIGNATURE:
Homework reports; attending the classes at least for 50 %.
EXAMINATION METHODS:
The final grade will be formed based on the following contributions: homework (30 %), written preparation of the final exam (30 %) and oral presentation/discussion of the final exam (40 %).
