The master course on mesoscale dynamics is adjust for students to upgrade their knowledge and understanding mesoscale dynamics. It explains the basic physical concept on dynamics of mesoscale atmospheric processes divided into five different topics:
• Definition of Mesoscale Dynamics and Mesoscale Processes;
• Basic equations and methods;
• Mesoscale instabilities
• Deep convection;
• Orographic Mesoscale Phenomena and Orographic precipitation
1) The master course starts with the main definition of Mesoscale Dynamics and mesoscale atmospheric processes. Using two commonly used methods for defining the scale (dynamical and scale analysis) for definition of the scale processes. Course follows with energy consideration, energy cascade, scale analysis of different mesoscale phenomena, scalability and interactions among them.
2)Then the fundamental principles of modeling mesoscale processes and construction of mesoscale atmospheric model, the basic equations and linearization are explained in detail in addition to transformation into spherical coordinates, inclusion of the orography. In the second part of this topic we turn to numerical techniques, total difference method, initial and boundary conditions, treatment of the surface processes, sub-scale parameterization, moisture, radiation and numerical integration.
3) The mesoscale instabilities topic is based on physical and dynamical consideration of the different types of instability resulting from the imbalance between the basic atmospheric forces. This topic is primarily focused on:
• Static (buoyancy) instability;
• Centrifugal-inertial;
• Symmetric;
• Shear (horizontal and Kelvin-Helmholtz).
4) The next important topic is a deep convection, definition of convection, shallow vs deep convection, the main physical processes, convective cloud parameters, storm classification, convective cloud model description and numerical simulations.
5) Orographic phenomena induced by air flow over mountain and orographic precipitation are also part of this master course. Here we intend to study the influence of the orography on mesoscale circulation-flow (mountain waves, lee waves, rotor clouds, downslope winds, derivation of Scorer number, Froud number, air flow blocking) and moisture processes or orographic precipitation.Goals (competences):
o To achieve advanced knowledge and understanding of the basic theoretical and practical concept of Mesoscale Dynamics.
o Develop capability to apply this upgraded knowledge in solving a different analytical and practical numerical solutions.
o Strengthen the capability and motivation for moving forward.
o Capacity building for further development and improvement with own idea and innovative solutions;
o Better preparedness for scientific presentation, talks, review and discussions
o Improve the scientific and research potential, as good initial input for the further PhD career.
Teaching methods:
Lectures supported by slide presentation, interactive lectures, trainings (using laboratory equipment and software packages), team work, case studies simulations, discussion, individual practical presentation (homework) , seminar paper, e-learning.
