Unit 8

Air Mass Formation and  Modification

So far we discussed the thermo-dynamical characteristics and the processes that an individual air parcel experiences and how they affect the characteristics of the air parcels. This unit will scale these to the concept of air masses and the movement of air masses under the aspect of the origins of synoptic weather forecasts.

Learning goal

Synopsis of the material learned so far

After completion of this unit students will be able to

  • Apply material learned in previous units to a new problem
  • Classify air masses and discuss the properties and formation
  • Interpret air mass modification, and their meteorological consequences for weather, climate and air quality
