Mid-Latitude Weather Systems - 2023 entry

In this module you will develop a mathematical and physical understanding of the dynamics of synoptic scale weather systems in the mid latitudes, including extratropical cyclones and fronts. You will explore conceptual models for the development of these weather systems and compare these with analytical models and observations. You will develop quantitative skills in the analysis of these weather systems, which are relevant to understanding what we see outside, and to making sense of surface and upper-level synoptic charts and weather forecasts. Through quasi-geostrophic theory, concepts of potential vorticity (PV) thinking will be used to understand where we might expect to see vertical motion and rainfall within these systems, and what impact moisture has on the development of systems. You will explore and discuss recent research in the field of midlatitude weather systems, enabling you to develop your critical thinking skills. The module will include a mix of instruction methods, including traditional lectures, videos, discussion classes, giving you varied opportunities to develop learning and organisational skills. You will, with other students, explore some of the research literature related to the mid latitude weather systems and discuss how the theory informs this research.  

 

Pre-requisite module: MTH3001 or MTH051 or equivalent. 

 

By the end of this module you will have an understanding of the origins of synoptic scale motions in the midlatitudes. The skills in being able to link mathematical descriptions of phenomena with observations of the atmosphere will be valuable for anyone with an interest in the weather we experience day-to-day. By examining topical research, you will understand the relevance of the mathematical and conceptual models for generating new knowledge of how the weather and climate system works. Knowledge of the systems discussed in this module will be ideal for careers involving meteorology (including forecasting), climate and environmental science and modelling. By engaging with research literature, you will develop critical analysis skills that will be essential for any scientific career.
