| Zusammenfassung |
| The urban heat island (UHI) effect is one prominent form of localized
anthropogenic climate modification. It represents a significant urban climate
problem since it occurs in the layer of the atmosphere where almost all
daily human activities take place. This paper presents the development of a
high-resolution modeling system that could be used for simulating the UHI
effect in the context of operational weather forecasting activities. The
modeling system is built around a state-of-the-art numerical weather
prediction model, properly modified to allow for the better representation of
the urban climate. The model performance in terms of simulating the
near-surface air temperature and thermal comfort conditions over the complex
urban area of Athens, Greece, is evaluated during a 1.5-month operational
implementation in the summer of 2010. Results from this case study reveal an
overall satisfactory performance of the modeling system. The discussion of
the results highlights the important role that, given the necessary
modifications, a meteorological model can play as a supporting tool for
developing successful heat island mitigation strategies. This is further
underlined through the operational character of the presented modeling
system. |
