discussed climate models at regional level; simulated the evaluation of urban warming in the different cities involved in the project, providing locally proper measuring
and analysis in connection with the specific urban forms.

1.1 General Introduction
The working package WP 3 collects technical and scientific definitions and state of
the art about the urban heat island phenomenon and further presents strategies to
simulate future scenarios by using modelling systems. The knowledge review is a
core output of action WP 3.1, giving a complete overview over the problem. It discusses methods to mitigate and adapt to the intensification of the UHI in Central
Europe (CE) and beyond and further provides background information for local
authorities related to urban planning, building and land use regulations in compliances
with EU rules. The review is developed with the contribution of all PPs, scientific
and institutional, in order to have main examples of excellences, best practices,
innovative regulations and intervention put in act to face the UHI phenomenon.
Working Package WP 3.2 discusses regional climate model simulations and tries to
give an estimation of future climate conditions (temperature, humidity, precipitation,
wind speed, cloud cover, etc.) which may serve as outer conditions for the assessment
of the UHI phenomenon in the cities of CE. The suitable simulations can be made e.g.
with WRF or RegCM, especially when urban land use parameterizations involved,
and statistical output on means and standard deviations of the meteorological variables can be supplied. The regional climate model uses available boundary conditions
provided by existing global climate models. Statistical downscaling techniques can be
used as well. Within the city structures, other microscale models are necessary to
provide estimates of the local conditions, e.g. in street canyons.
The project partners being involved in this action try to show possibilities to
simulate the effect of the Urban Heat Island and analyse its characteristic features
for their city of interest. They try to set up models with different backgrounds also
to account for simulation of mitigation scenarios counteracting this urban climate
