Target group

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.

Prerequisites

Atmospheric thermodynamics and Introduction to atmospheric flow dynamics

Learning outcomes

  • 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.

Timing

1. or 2. year in MSc studies.

The course will be lectured every year in the III period.

Contents

  • 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

Activities and teaching methods in support of learning

Weekly lectures, a couple of short guest lectures by FMI researchers/meteorologists

Study materials

Lecture notes, handouts, and figures from Markowski and Richardson: Mesoscale meteorology in midlatitudes

Supplementary material: Markowski and Richardson: Mesoscale meteorology in midlatitudes and two research papers by Hannu Savijärvi

Assessment practices and criteria

Grade is based on final exam

Recommended optional studies

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.
