Description

The urbanization in the Pearl River Delta region of China, including Hong Kong, has been unprecedented in the past few decades. Some of the environmental consequences associated with the rapid urbanization are obvious, such as the severe air pollution, while others are poorly understood. At present, the most effect way of assessing the impact of urbanization is through advanced numerical modelling. It is however a major scientific challenge to quantify the exchanges of energy, mass and momentum between the atmosphere and urban surfaces, because the physical processes involved are extremely complex. The objective of this project is to develop a new urban surface parameterization scheme for regional atmospheric modelling. The scheme will be tested against observations and then coupled with a regional atmospheric model, resulting in a better understanding of the impact of urbanization on the behaviour of the atmosphere in the Pearl River Delta region. It will also better predict major environmental events, such as severe air pollution.
