Objectives

This module brings together a range of topics from across the atmospheric sciences which are of importance for Environmental Scientists. These will cover the broad theme of meteorology and weather forecasting, climate change processes and air quality and atmospheric chemistry.

Meteorology and Weather Forecasting

- to understand and appreciate the dynamical, physical processes which occur in the earth's atmosphere;
- use basic standard methods to analyse the atmosphere and make weather forecasts;
- to gain an understanding of the numerical approximations and limitations of Numerical Weather Prediction Models;
- to gain expertise in the critical analysis and appreciation of data provided from the computer simulations;
- to enable students to run a state of the art NWP model;
- present complex meteorological data and forecasts to users, in written and televised formats.
- understand the value of forecasts to diverse users;
- to provide transferable skills in area of scientific interpretation.

Climate change processes

- The coupling and feedback systems between the atmosphere and ocean that is driving energy transfer and climate change.
- Concepts of surface exchange of heat fluxes and greenhouse gas transfer between atmosphere/land/ocean/biosphere.
- The role of clouds in the climate system, including their effect on radiation and energy transfer.
- How clouds are parametrised in climate models and the very large uncertainties in their effect on climate change.
- The response of the upper oceans mixed layer and water mass formation to air-sea fluxes in a changing atmospheric/ocean system and its effect on the thermohaline circulation.
- The scientific aspects, predictions and consequences of the recession of sea ice on global sea levels.
- How all these climate processes can be simplified and parametrised in climate models, and appreciate what limitations these introduce in the models.


Air Quality and Atmospheric Chemistry

By the end of this module students will have an understanding of the sources and processing of air pollution in the troposphere and stratosphere, its impacts on human health and ecosystems, and its interactions with the climate system. This will include a knowledge of the sources and sinks of air pollutants on a range of scales (such as UK national air quality strategy pollutants, greenhouse gases, ozone-depleting gases, transboundary pollutants, hazardous air pollutants); impact upon human and environmental health; measurement and monitoring; improvement technologies, emissions control strategies and the economic implications of these. On completion of the module students should be able to understand and use a simple computer box model to predict response of air pollution to different emission changes and climatic changes, perform analysis of computer model output and present scientific results suitable for use by politicians or consultants.

Skills outcomes
- the ability to use and run a variety of computer models including state of the art atmospheric numerical weather prediction models and a range of simpler models for weather, climate and air quality applications;
- to critically evaluate and analyse complex data produced by models and to work to the tight time-pressure required for producing a forecast.
- to be able to use model output data to generate a forecast suitable for the general public, and to provide critical evaluation of quality of the results;
- to improve scientific appreciation of the limitations of advanced numerical codes and the methods of obtaining a numerical solution of the equations;
- to understand the physical processes being represented in the numerical computer model, in terms of the equations being solved for the dynamics, and the parameterisations for unresolved processes.
