Master’s Programme in Atmospheric Sciences is responsible for the course.
Module where the course belongs to:
- ATM300 Advanced Studies in Atmospheric Sciences
- Study Track in Meteorology
The course is available to students from other degree programmes.
Atmospheric thermodynamics and Introduction to atmospheric flow dynamics
Synoptics I and II
Convective weather systems and climate is recommended if the student wants to learn more about atmospheric deep convection and hazards caused by it.
- Understanding instability mechanisms and applying them to mesometeorological phenomena
- Understanding when and why a phenomenon is hydrostatic
- Understanding the reasons and consequences of dynamic and buoyancy related nonhydrostatic pressure gradients in mesoscale phenomena
- Understanding the physical formation mechanisms and dependence on different factors of boundary layer phenomena, frontal rain, mesoscale cyclones, deep moist convection and associated phenomena, hazards associated with deep convection (e.g. tornadoes), hurricanes and orographic phenomena.
1. or 2. year in MSc studies.
The course will be lectured every year in the III period.
- Scale analysis
- Nonhydrostatic vs hydrostatic phenomena
- Dynamic and buoyancy related nonhydrostatic pressure anomalies and their consequences
- Static, inertial, symmetric and shear instabilities
- Boundary layer: convection in boundary layer, orographic precipitation, sea-land breeze, low level jet, Blackadar mechanism, coastal convergence, coastal snow storms, lake effect
- Frontal rain, mesolows
- Deep convection and associated phenomena including initiation of convection, elevated convection, convective parameters, single cell, multicell and supercell convection, propagation of convection and effect of shear on it, mesocyclone formation in a supercell, propagation of supercells as a result of nonhydrostatic pressure gradient associated with "spin" and shear, MCSs, MCCs, bow echo, squall lines, tornadoes and their formation mechanism, downdrafts, hail, tropical cyclones
- Orographic phenomena
